Hi,
On a Windows Server 2012 R2 I'm using the GUI to convert my disks from VHD to VHDX.
All goes well but my 8 GB dynamic VHD file gets about 60 GB after conversion to VHDX!!
I've also tried PowerShell with or without the -Dynamic parameter.
I have a couple of VHD files that do get a couple of GB larger then the original VHD file.
I've read articles on the net where you get around 145 MB extra on the VHDX but mine is getting huge in difference.
Any ideas why this is?
Kind regards,
Bhavesh
Hi Guys,
I've done a validation on one of our clusters here, and some of the updates are missing on a host. Which is no big deal, until I try and download them, and get told they're invalid!
I've double checked I've not done anything stupid, and have downloaded the correct ones for the OS (Server 2008 R2 Hyper-V SP1) and they all fail saying this update is not applicable, when they actually are! Any ideas on a valid download location for the following that I can use...?

Hi all, I've got a strange issue that i've been trying to resolve. Quick overview: I have a four node hv2012 cluster with four nics in each node set up with two nic teams. One team has two interfaces, one for management and one for the cluster heartbeat
network. Team two has three interfaces; one for all the vms, and the other two for interfaces on networks connecting to our SAN. Here's the problem: I create either a Win2012 or Win2008R2 virtual machine and then start the vm and change the vm nic so that
it has a static ip address instead of a DHCP address. Sometimes, when the virtual machine reboots, you can see in Hyper-v manager on the networking tab at the bottom of the screen that it gets the static ip address that its been set to, then after about 60
seconds, it gets a second ip address of 169.254.x.y, which is the DHCP Automatic Private IP Address. How can that possibly happen when you set the ip address of a nic to a static ip address? It doesn't happen after every reboot but it will happen again
after several reboots. When the 169.254.x.y address gets assigned, the machine can't ping anything until you either disable/enable the nic or reboot again. I've been up and down through the logs and network settings and i just can't figure out why this is
happening. Does anyone have any ideas about what might be causing this or what to look for? Any feedback greatly appreciated.
I have FTP installed on my Hyper-V server. In my Web page I have the following:
<a href ftp://207.28.29.231>FTP to your Files</a>
Where 207.28.29.231 is the public IP address of my router. I have port forwarding turned on to point to my Server2008r2. However, my web server is actually in Hyper-V. Does that mean I have to port forward to my HyperV server instead of Server2008r2?

Hi,
I have had a problem for several days and cannot seem to solve this.
I cannot get SharedNothing Live Migration to work at all, not even with a brand new 4mb empty virtual machine. I am running Server 2012 Datacenter R2 Preview on a host and Hyper-V 2012 Server core on another. The datacenter is acting as an ADDS,DNS, DHCP server & Hyper-V manager.
I have setup the usual requirements for SharedNothing, Constrained delegation (for both machines) DHCP with dynamic DNS updates to the Active Directory Store. configured Forward and Reverse zones, the Roothint resolution, DHCP Server options (DNS Name, Router, etc). Currently the setup is Static IPv4 Datacenter with DHCP IPv4 for the Hyper-V Server OS. Matching virtual switches and all the other common guidelines provided by microsoft and other hyper-v users.
There is no clustering or fail-over settings defined. The AD DS groups for Administrator and the Computers are all correct. Name resolution and PING works to and from the Machines, so does Server Pool management.
I've tried different switches (physical), ensured all the hardware (storage etc) on the machines are healthy and have reloaded the server OS's several times while trying varying configurations to make the Live migration feature work. but whether the VM is 15gb or 5mb, the Migration just fails to successfully complete.
I always receive the same error message, with CredSPP, Kerebos, with any of the transfer options at all.
I spent the past few days looking over google to see if anybody has posted the same kind of error message to no avail.
I snapped a picture (will post it when the forum allows me to) of it and also will note I am getting an eventlog message (intermittently) which may also be related to my primary issue.
Error 21026 Microsoft-Windows-Hyper-V-VMMS
Virtual machine migration operation for 'LSERVERVM' failed at migration destination 'CONTROLLER'. (Virtual machine ID typical id string)
This above error message is directly related and I cant find any advice on how to troubleshoot it.
The below error message may also be related, however only seems to crop up in the event viewer under certain network configuration.(whether ipv6 is on or off)
Error 20406 Microsoft-Windows-Hyper-V-VMMS
The Virtual Machine Management Service failed to setup the listen socket for Virtual Machine migration connections for address '192.168.2.2':The requested address is not valid in its context. (0x80072741)
[x.x.2.2 is my destination IP]
I'm really struggling here guys, any advice is greatly appreciated, if you have any questions about my setup I will gladly answer them as soon as possible.
So, i had Server 2008 R2 running this no problem using the HVRemote tool, so i did a similar process again and i can connect to the Hyper V Manger but i cant see my VMs, i did the /show command and got this odd error:
3: - Connect to root\cimv2 WMI namespaceAny one got any ideas?
I am experiencing several errors on my san switches on ports that my hyper-v cluster servers are plugged into.
2 SANbox 5802 FC Switch
1 XIO ISE2
2 Dell R710
The two dell servers are part of a hyper-v cluster. I have two vm's running in the hyper-v cluster that is a guest cluster.
Each server has a dual port qlogic QLE2562 hba. One port goes to one san switch and one goes to the other.
Each hyper-v server has two VSAN's setup on each and each one is mapped to a different port on the QLE2562.
2 Server 2008 R2 Vm's running guest SQL cluster
Each Guest VM has two Fibre Channel adapters which means that each VM has 4 WWPN's for a total of 8. By default hyper-v sets the WWNN all to the same address for every fibre channel adapter I add. Does this matter? I feel like I should change the WWNN so each of the virtual Fibre Channel adapters should have a unigue WWNN so I should have 2 WWNN for each VM and 4 total of both VM's. Is this not the case? Should I leave them the same?? I can't find any documentation about whether the WWNN should be changed. It seems like I should.
On SAN switchs, specific to the ports the hyper-v servers are connected to I see several of these messages that happen every so often.:
"
][Eport][Port: 3][Received 1 frame(s) from address not in hard zone (current frame src address = 0x10000, dest address = 0x10301)]"
Anyone have any thoughts to why I am seeing this message and about how the WWNN should be configured?
Thank you for your time.
I have recently taken over for a system administrator and we are having tons of issues with or domain and Hyper-V servers. Oh the joys of taking over someone elses mess. In the event viewer for Virtual1 (Hyper-V Windows 2008 r2, we are receiving an NetBT Error message. I have posted below the nvtstat -n. I have read through many posts that this is how to diagnosis the problem but don't understand what to do from here. Any suggestions for the forum would be much appreciated.
** Edited to add that we are not running WINS
Thanks

Hi All,
I'm trying to connect to my core from my win7 machine Hyper-v manager, I'm using a simple workgroup-subnet in my office.
I'm always getting "You do not have required permissions..."
I tried adding via the core command line to add my workgroup local user but still same issue.
How do I resolve this kind of issue.
Thanks
I am looking at some suggestions for best practice for setting up a hyper V 2008 r2 at a remote location with 5 nics, one for managment vlan and other 4 on the data vlan. This server will host 2 virtual machines, one is a DC and the other is a member local DHCP server. The server is setup now with one nic on the management Vlan and the other nic's set to get there ip from the local dhcp server on on the host. We have the virtual networks setup in Hyper V to point to each of the nics using the "external connection". The virtual servers 'DHCP and AD" have there own ip set within them. Issues we are seeing, when the site looses external connections for a while they cannot get ip addresses from the local dhcp server anymore.
1. NIC on management Vlan -- IP Static -- Physical host
2. NIC on the Data network Vlan -- DHCP linked as a connection "external" in Hyper V -- virtual server DHCP
3. NIC on the Data network Vlan -- DHCP linked as a connection "external" in Hyper V -- Virtual server domain controller
4. NIC on the Data network Vlan -- DHCP linked as a connection "external" in Hyper V -- extra
5. NIC on the Data network Vlan -- DHCP linked as a connection "external" in Hyper V -- extra
Thanks in advance
Hi,
I setup the Hyper-V 2012 r2 core and setup a VM with win 8 and VMM trying to manage the Hyper-V remotely. I can connect to the Hyper-V from the VMM but getting error when trying to create a virtual HDD. Attached the photo.
Any idea??
Hi
When i do install a new virtual machine on hyper- v where is it stored?
so can I copy this virtual machine file and use it in another hyper-v machine?
thanks?
Dear community,
it is not clear to me, if it is possible or not to dedup a CSV attached to a Hyper-V Cluster.
We have three Hyper-V 2012R2 nodes and a CSV hosted by a SAN, not a SMB-Share.
This CSV is mounted at c:\ClusterStorage\Volume1.
Server Manager Shows "Configure Data Deduplication" (File and Storage Services - Volumes" and I wonder what to configure:
"General purpose file Server"
"VDI Server"
We are using Hyper-V only to host Windows Servers, no VDI by now.
Stored on that CSV are the VHDX and configuration of that virtual machines.
What should/could I configure to take Advantage of deduplication?
Regards
Davorin
Hello All,
I'm trying to solve a particular problem, and part of that solution is the Shared Virtual Disk feature of Hyper-V 2012 R2. What I have is a script that creates VMs at "run time" utilizing differencing disks off a primary parent VM. All of these new VMs need to share a disk of known files (build tools, drivers) across the board for the VMs. The script I have creates New VMs and adds a SCSI controller to each VM, then attaches the VHDX to the SCSI controller, however there is no setting that I can find in Powershell to enable this to be a SHARED DISK.
Instructions for enabling Shared disk are found here:
http://technet.microsoft.com/en-us/library/dn282283.aspx
Instructions for Add-VMHardDiskDrive are here:
http://technet.microsoft.com/en-us/library/hh848470.aspx
None of them specify the ability to set the disk to Shared in Powershell...
Any tips?
Thanks

Hi,
I'm getting this message on my node 1:
This is my quorum disk. I tried this:
rd /s E:\$RECYCLE.BIN (Elevated Command Prompt)
Source:
And it doesn't work:
How can I fix that?
If I open the Recycle Bin, Windows becomes kinda unstable. My node 2 doesn't have this issue.
Thanks in advanced.
Hi,
When I convert a dynamic VHD to Fixed size I get an error message. The disk is on a SAN volume (200GB). The VHD is a 21GB file. There are no snapshots involved.
If I choose to convert the file and select the same file to convert I get: The file exists. SO..
If I choose to convert the file and select the a different file name I get: There is not enough space on the disk.
There is plenty of SAN storage, so do I need to expand or compact the disk prior to conversion?
Any advice would be great, thanks Matt.
But you cannot have both Hyper-V and SoFS on the same hosts.
Please clarify the above statement from the Post
My reason for asking. Been studying Hyper-V Windows 2012 for a year. Proposed Cluster;
1. Hardware 3 identical servers. OS's are 2 drives mirrored. 4 JBOD pass through 1 tb drives per server using 1 onboard SAS controller per box. (Intel S2600GZ MB)
All 3 in a Cluster with Host Storage Spaces, SMB. SOFS for Virtual VHD Disks and VHD Files. Classic File Services for Metadata access.
2 Virtual Machines per host. These virtual machines are 2 AD DC'S, 1 Exchange Server, 1 Remote Desktop Services Applications Server, 1 SQL Server (Contact Business Manager and Access Dbases) and 1 PSQL Server (Enterpise Product Management.) The workload
traffic is small - 50 users. Staff also uses Office Suite.
It is my thought to combine the Cluster HA and the SOFS/CFS Roles. This post mentioned is the first I have come across stating the Hyper-V and SOFS must be on different hosts. Please explain the rationale and data to support this statement, as I may need to go back to the drawing board.

Hi, I have an issue currently where I am trying to Migrate guests VM's from one 2012 10 node cluster to a new 2012 R2 10 Node Cluster. The setup is as follows :-
The Strange thing is this issue seems random, I have has some machines Live Migrate fine, and some fail, the ones that fail always fail. for example I have a SQL Server SV-SQL09 with one IDE VHDX and one SCSI disk, this always fails to migrate.
Migration works fine when the guests are off.
The migration Starts fine, the folder is created on the Share, and it copies over both VHDX files ok. its at the next steps it always fails. So I am a bit Stuck, not sure what's going on if some work and some fail. !!
My initial thought's is some Network Timing issue as the process is being controlled via SCVMM. I have recently upgraded to SCVMM 2012 R2, and have some other issues with hosts randomly going into needs attention when all the status shows fine winrm is fine too. any help or pointers would be greatly appreciated.
ERROR on SCVMM 2012 R2 :-
Error (12700)

I'm trying to get an idea on general best practice with this situation that most are using.. isolation, updating etc..
We have a new offsite hyper-v box that will host vm's for IIS and SQL..
Example boxes:
VSIISDedi02 is the iis box and currently has two virtual nics.. one with a public ip for external access and an internal nic for local (192.168.0.4)..
VSSQLdedi02 has sql on it.. has the same two virtual nics, but currently i have the external nic disabled.. i only enable if i need to do a windows update (not ideal)..
All of this sits behind a firewall which we have no direct access to make changes on.. must contact the hosting company and open ports etc..
What is more typical with this situation.. just to leave the public and private nics enabled and windows updates and external access open? Or to configure a 3rd box that is a firewall server of some kind and or dns? And finally.. what about joining these two to another box that is a domain controller.. (i think a DC isnt needed)..
Any thoughts on this
I'm guessing a 3rd box thats a firewall externally accessible box, that would allow the sql box for instance, to connect and do windows updates?
Thanks in advance

We're about to put our first virtualized Windows 2012 Hyper-V server on a small business site. Everything went fine with the installation, but I've noticed that when loading up the virtual machines, the process takes hours... For example, I created a new virtual machine with 4GBs of RAM, and installed Windows 7 64-bit edition from an ISO file... It took about two hours. I deleted this virtual machine and tried to create another Windows 7 64-bit virtual machine, this time using the actual DVD and it was just as slow.. EVEN with all other VMs shut down... I have another test copy of Hyper-V for Windows 8 at home that I use for learning, so I tried installing the same Windows 7 64-bit ISO on this workstation and it installed in twenty minutes. And this is just a workstation.
The server is a HP Proliant ML350 server with 24GBs RAM. If anything I would have expected the server to install the Windows 64-bit VM in twenty minutes, NOT the workstation !! On the face of it the only differences between the two systems is:
a) The server has two 500GB SAS drives, which are mirrored. There is no mirroring on the Windows 8 workstation.
b) The server had drive is partitioned in to a C: drive (for the host O/S) and a D: drive (for the virtual machines). There is only one partition on the Windows 8 workstation, which holds the operating system and the virtual machines.
Below is a graphic I drew up which I hope helps you visualise the hard drive setup.
This is a small site, so they wont pay for additional hard drives. Is there something about the way I have the disks set up that could cause the virtual machines to load slowly? Would it be better NOT to have two partitions on the host?
Thanks in advance for any advice offered.
