Dear Friends
I have SQL database in one of a VM, It was working fine, Since yesterday it keeps on restarting itself
I had excluded this machine from the domain, as it was having the trust relationship issue, so I thought I should remove from domain and add to domain again (normal Practice).
But after that, it is restarting every 34 seconds and I am unable to do anything
CAN ANY ONE HELP - IT IS EXTREMELY URGENT
While the firewall is opened , i can't expand the VHD size , it takes long time for requesting information ,
When i set the firewall off , i can expand the disk so quickly
My question , what is the firewall port to be opened instead of disable the firewall?

Hyper-V 2012 R2. We have a SE3016 JBOD devices that hooked up to the physical server via SAS 6mbps HBA. On the physical server (2012 r2 core), diskpart lists the disk as offline. In hyper-v manager in the settings of the VM, i have added the hard drive via scsi:
As you can see, the physical drive shows up in the settings. However, when i go into computer management of the VM, the drive is not listed there. The lights for the drive in the JBOD device is light-up and does not show any erros. I have rebooted the server and JBOD device. Still no drive in computer management of the VM.
Am i doing this process right to get the VM to see the drive?
Hi all
I have been researching to see if it's at all possible to convert a Gen2 VM in Hyper-V to a Gen1.
I recently created a 2012R2 RDS server in Hyper-V and introduced to production environment, but now I want to introduce RemoteFX which I cant do for Gen2 VM's.
I have seen forums indicating this cant be done, but what if I was to recreate a VM as Gen1 but re-use the existing VHDX file I used in the original Gen2 VM? Would this work? Why/Why not? Is there anything else I could do to convert back to Gen1?
Any suggestions would be appreciated.
Hi,
I had just downloaded a version of Windows Server 2012 Hyper V and successfully ran it in a VMWare 10, created a admin profile too. Post installation when i login to the box i just see a blue screen as a landing page with no taskbars or a MMC. I plan to set it up as a clustered node , creating another VM (starting with 2). Any suggestions would be appreciated. Thanks.
Hey all,
I'm running server 2012 R2, and i'm trying to run server2k as VM, so far the disk image and all looks good, first bootup works fine and i can login into the 2k server and do my changes, but if i reboot just once i will be faced with BSOD inaccessible_boot_device, now mounting the vhd shows drive as RAW and not NTFS :/ i have checkpoints and backups so i have being trying all over again and again with different settings etc, but no dice, does anyone have any ideas ?
I work for an IT company that just recently signed a client that uses a clustered Hyper-V environment running on Windows Server 2008r2, and uses Shared Cluster Storage or Shared Volume. The setup seems very strange to me. They are configured in a fail over cluster, and both Hosts have their own servers running on them. They both store their VMs at C:\ClusterStorage\Volume1, which is really an iSCSI connection to a SAN.
On Host1 you can see the 7TB drive in Disk Management and it shows as online, but there are no drive letters or folder path assigned to it. In Failover Cluster Manager, you can see that Host1 is the owner. Host1 also holds the Quorum drive (I
do believe it was on Host2 before)
On Host2 you can see the 7TB drive in Disk Management but it shows as offline, and of course no drive letter or path assigned to it.
Both hosts use this volume, and somehow it is mapped to C:\ClusterStorage\Volume1. Is this how a normal Hyper-V storage cluster looks and works? We are able to move servers from one host to the other no problem, and creating a file or folder on one C drive shows up on the other. Both Hosts have been up for over 390 days, and im wondering if something was changed and removed and when we reboot the hosts if they are going to lose their mapping to the shared volume, or is this is really configured somewhere else like in either Hyper-V manager or Failover cluster manager that I am just not seeing
Thanks
Hi - I have this relatively old 2008R2 file server (8GB memory and 25TB disk) I'd like to use as file storage for a SQL Server VM. The network is a 1GB switched configuration. The VM resides on relatively new hardware (Server 2012, SAS) but doesn't have a lot of disk. I'd like to make a bunch of the file server space available for SQL Server Data (2008R2) - its a small network (10 users) that we want to load a bunch of glob data indexed by a few keywords as reference. Kind of like a GIS database. My first thought is to create fixed vhdx file on the file server via Hyper-V manager, but this takes days to initialize for the size I'm thinking of (10TB). I created an expanding disk and it was pretty quick to create. I copied a 4GB file over the net to the mounted (from the Hyper-V Host) vhdx file and it went pretty fast. I thought about using the iSCSI trick to attach it to the SQL VM (turning the file server into a SAN sort of?), but I'm wondering if this is overkill. I'm just looking for a few suggestions. There is a lot of stuff out there, some of it conflicting, about storage configuration.
Thanks
Hi there,
Would anyone be able to please advise as to how I can change the subnet mask for a Windows Server 2012R2 Cluster.
There are two windows server 2012R2 hosts with failove clustering and the hyper-v role installed.
Each host has teams of 2X1GB nics for Management (cluster comms allowed), Live Migration, Cluster (Dedicated), VM Network.
Host1: Management: 192.168.1.1/24, Cluster : 192.168.4.1, Live Migration: 192.168.5.1.
Host2: Management: 192.168.1.2/24, Cluster : 192.168.4.2, Live Migration: 192.168.5.2.
The subnet mask only needs to be changed on the Management Nic team. It needs to have a subnet mask of 255.255.254.0 as the network has changed to 192.168.0.0/23 to allow for more IPs. The DNS (192.168.1.11) and default gateway(192.168.1.254) remain the same. The new host IP on host 1 would therefore be 192.168.1.1/ 255.255.254.0 and on host 2 it would be 192.168.1.2/ 255.255.254.0.
Thanks,

Hope someone has an easy answer to this...!
I have a Windows 2008 SP2 server (physical) that houses a critical SQL database and Apache Server. What I want to do is have another server at a DR site with Server 2012 r2 preferably and have a Virtual machine setup that will replicate the Windows 2008 server. I want to do this without changing anything on the physical server now.
I have looked at Double Take availability but the target DR server has to be 2008 sp2 as well. I just want the simplest way to do this where if the 2008 source goes down they can continue working at the DR site if need be. What do you suggest?
Hi
how can i migrate 70 virtual machines that are running on Vmware hosts to 2012 R2 Hyper-v hosts
Hello everyone!
I have two hardware servers, one is 2008R2 Hyper-V host and another one is 2012R2 Hyper-V host.
I need to move virtualized DC (2008R2 Server, FSMO roles) from 2008R2 host to 2012R2 Hyper-V host. As far as i know export/import is not correct way to do such move of DC between Hyper-V hosts.
There are couple of other different opinions on forums about it, like shutdown the VM, copy .vhd file and recreate VM, etc, etc...
Which way to do it is valid?
Thanks in advance and sorry from my ugly english (not my native language).
Hi,
I configured hyper-V in windows server-2012. I have configured Xampp server in that Hyper-V machine. The IP address of the Hyper-V machine is 192.168.50.68.
Iam unable to access that Xampp server from other system with the IP address. And iam unable to ping to that Hyper-V server from other machines in the network. When i try to ping to that IP, it it saying as destination host unreachable.

Hello,
I'm trying to find out if I can use a single SMB share with multiple Hyper-V Clusters. Looking at:
How to Assign SMB 3.0 File Shares to Hyper-V Hosts and Clusters in VMM
I think it's possible. Since the File Server is going to handle the file locking it shouldn't be a problem.
Has anyone tried that?
Thank you in advance!
Hi.
I am currently investigating the possibility to run a remote desktop gateway on an virtual machine, and connecting to it (udp) threw the wmbus instead of a network adapter. It such a thing possible? Basically what I am asking is if I get use the VMBUS to connect to machine as i would a network adapter (on a specific upd port).
I ran across a post enabling debugging threw the VMBUS (I think): http://withinrafael.com/how-to-set-up-synthetic-kernel-debugging-for-hyper-v-virtual-machines/ if this is any way related to my question.
Cheers
Hi all,
we are currently implementing a backup solution to back up our HyperV2012R2 Failover Cluster VM's. The VM's have their disks on a 2012 R2 StorageSpaces Server shared via SMB3. The 'file server vss agent' service is installed on the storage system.
The HyperV host has several nics.
-One 1Gbit nic for management. The Host is registered in AD with this nic and the DNS entry points to his DNS name 'server.domain.local'
- One 10Gbit nic for the SMB Storage traffic in another subnet. The storage machine has a second Name who points to the ip of the 10G nic 'storage.domain.local'
- Other nics for cluster communication and VM traffic
The VMs are configured with the 10G name of the storage server and everything works well with hyperv.
Everytime i try to back up a machine (via the Software or with the Shell on an Hyper-V Host via DISKSHADOW) there is the following error message:
--------
DISKSHADOW> add volume \\storage.domain.local\vms01\server01
The provider does not support volume shadow copies for this volume in this context.
You must either change the context or add a different volume.
Note that changing the context might cause existing volumes in the shadow copy set to become unsupported.
--------
When i use his AD DNS name it works:
--------
DISKSHADOW> add volume \\server.domain.local\vms01\server01
DISKSHADOW> create
....
--------
Am i missing something? Has anybody an idea what the problem could be? Do I have to register the second name or nic in the storage server system or in the VSS providers?
Thank you for any help!
