Hello Community
When use Hyper-V, do you install Hyper-V and then
install VMWare and create the virtual machines using the VMWare software
or does Hyper-V itself create the virtual machines without any 3rd party software?
Thank you

Creating checkpoint causes VM to restart
Just wondering if anyones experienced this?
I have a customer with a 4 Node 2012R2 Hyper-V Cluster.
Sometimes performing a checkpoint will cause a VM to reboot. It's happened to both VM's running windows 2008R2 and 2012R2 with latest versions of integration tools installed.
Anyone ever seen this behaviour?
Thanks

2012 R2 VMs crashing with BSOD "Critical_Structure_Corruption"
I've used the search within that Forum, but I did not find any suitable hints or Solutions.
Host is Windows Server 2012 R2 Datacenter with Hyper-V Role enabled. On that Host several Generation 2 VMs are running with Windows Server 2012 R2. Those VMs regularily chrash with "Critical_Structure_Corruption" BSOD.
I found a hint that Intel's HAXM Driver could be responsible for this, but afaik it is not used in my case. For ESX there is a workaround to select CPUID mask.
Hardware of the affected host:
- Intel XEON X3470
- Ìntel SATA RAID Controller
- 16 GB RAM
The Dumpfiles are located here:
https://onedrive.live.com/redir?resid=D23F5B3DC2B36670%21158
Doing the analysis by myself, I could not find any hints within there.
Two more advises:
- Generation 2 VMs with Windows Server 2012 RTM (non R2) on the same host do not crash!
- Gereration 2 VMs with Windows Server 2012 R2 on another host do not crash, too!
Any ideas?
Thanks in Advance,
Thomas

problems after doing P2V of Windows Web Server
We recently performed a P2v of our Windows 2003 Web Server. This server is our SolarWinds Network Performance Monitor (NPM) server. After the conversion, all the servers connecting to the SolarWinds NPM server lost connection monitoring. We had to manually restart SNMP on all of them. However, shortly thereafter, all our Web Servers started to alert because they could not maintain an SNMP service connection. A reboot of the server fixed it for awhile. But, the alerts keep coming. And, we can regain connection by rebooting the server or restarting the SNMP service.
has anyone seen this condition before? If so, how did you resolve it? I have checked each time this occurs at there are 2 processes that stop: w3wp and inetinfo.

Windows Hyper-V Server 2012 R2 - VM over network share on FreeNAS
Good day IT folks,
Hyper-V Server 2012 R2 has a feature on creating VMs over the network share (SMB 3.0).
I tried this on a network share on FreeNAS, my SMB version is 3.0, but I get some error creating VHD/VHDX on the network share. Is the error something to do with my FreeNAS?

Join differnet subnet PC to domain
i have one DC in my LAN environment and IP scheme is 192.168.0.1/24, yesterday i got another server and installed vm via hyper v on it. the ip allocated to this vm is 172.16.10.10, my simple task is to join the vm to my DC. my physical resources are limited. so i have installed RRAS 2012 on hyper v server which has 2 two nics. one nic ip is 192.168.0.118 and the other is 172.16.10.1, both are connected to switch.
i have configure the RRAS via selecting the option "secure connection b/w two networks". then i assign GW to my vm 172.16.10.10 and can ping both nics ip but unable to ping my DC ip, and cant join this vm into DC. can some one guide me towards the right direction if there is something missing ? tnx

Hyper v replica for multiple sites
Hi
I support 3 sites and would like two of them running hyper v to replicate back to the same replica site and server. Is this possible to have two hyper v sites replicate back to the same server based at another location or do they require their own individual replica server?
Thanks in advance

Deploy ASP.Net/SQL Server Solution to Windows Server
Hello,
Please advise if my understanding is correct:
We plan to develop an ASP.Net web application/OLAP DB with Visual Studio 2012, SQL Server 2012 Enterprise and SSDT.
Our DEV machine has all required software (above).
Our TEST machine has Windows Server 2008 R2 but no SQL Server instance.
Our PROD server has Windows Server 2012 but no SQL Server instance.
Can you please advise what is required for a deployment to both TEST and PROD?
Will we require a new SQL Server installation on both machines?
Can we use a Virtual Machine on both TEST and PROD environment to replicate our DEV environment?
With our current situation, what would be our best method?
Appreciate in advance.

Slow storage migration on converged 3-node network cluster
I've created a 3-node Hyper-V cluster (2012 R2) out of 3 former standalone Hyper-V host servers, using a converged networking model andfollowing this setup almost exactly. I've added an iSCSI NAS (QNAP) set up as a CSV, and thefirst VM that I live migrated to cluster storage took 11+hours for about 1.5 GB of VHD files(!). There shouldn't have been any existing cluster-related traffic to even load-balance, and a straight copy of a file that size to the NAS should take < 20 sec. Briefly, here's my config:
- NAS has (4) teamed 1Gb NICs (in testing, I'm getting ~112 MB/s to a hosted file share).
- NAS is on our main internal network (10.10.10.x) because it will also be used for minor file sharing duties.
- Each cluster server has (4) 1Gb NICs. I've added 3 of them to an LBFO team without management OS access, and reserved the 4th for remote host access.
Question: Is this necessary? Unfortunately, when I enabled management OS access on the LBFO team adapter, each NIC on each server grabbed an IP via DHCP, and I want to avoid that. - Misc. acronyms: MPIO is set up and working per QNAP's docs, the servers/NICs support VMQ and RSS, but not RDMA or SR-IOV. I turned on Jumbo Frames across the fabric, but I ran into issues and the cluster seemed to break - turning it back off
seemed to fix things (I think it may be because QNAP supports a frame size of 9000 and the Broadcom NICs show 9014).
Question: I assume server restarts aren't needed - it's just a matter of turning on Jumbo Frames on the NAS, switches, and host NICs, correct?
TechEd webcasts and the dark depths of the Interwebz make me think my converged configuration is supported. With that said, my key questions are:
- Most importantly: It looks like MPIO & iSCSI is supported with LBFO-teamed NICs if you use the MS solution and not a vendor's. However, should I be trying to do afully converged solution that uses all 4 NICs, and for which there's a virtual Storage VLAN on the virtual switch for my NAS (like the MS best practices example, but with iSCSI instead of SMB, if that's possible)?Or should I dedicate 2 of the physical NICs to the NAS, and have the other 2 NICs in a team that handles the rest of the roles?
- Should I only have 1 MPIO session per 1 NIC in the team, or does that matter?
- I did add the "Management" virtual network in the sample configuration, but I just realized that's probably redundant with the dedicated "Host Access" NICs that I reserved. Should I remove that network, or leave it and add the extra NIC to the LBFO team?
- Are there additional QoS settings that I should check/tweak? Should I shift minimum bandwidth weightings just for the period that I'll be migrating VMs?
- Is there any way to get all of my clustered virtual networks imported into SCVMM 2012 R2 for management? The lowest level of entity that I can manage in a UI seems to be a virtual switch. That's fine, but if MS is encouraging adoption of converged networking, I would expect their tooling and UIs to have better support for it.
It seems as if the cluster is running fine in general, but the slow storage migration is killing me, and I assume it can only get slower as I add new VMs to cluster storage. My best guess is that the virtual networks aren't set up properly somehow...thoughts?

Network Connectivity works in only 1 VM on Windows 2012 Server
I have an issue with a Windows 2012 Standard server running Hyper-V in a Cluster that will only allow one VM use networking. The server is a Dell R710 with 4 x Broadcom network ports and 4 x Intel network ports. I have the 4 Intel ports used for SAN storage, and the Broadcom’s for Hyper-V. I have tried with Windows 2012 NIC teaming, Broadcom teaming, and also without teaming on a single network interface. I currently have two VM’s, both are attached to the same External Switch, and both see the virtual nic, but only one gets network/internet connectivity.
I have verified the Bios and all firmware is up to date, and all 2012 updates are in place. I’ve deleted the virtial switch and re-created, removed connectivity to System Center 2012… aside from rebuilding this server, I do not know what to try next.
As far as I can see I am not receiving any errors. Any assistance would be greatly appreciated. I’ve built a few 2012 Hyper-V server, clustered and connected to System Center, and have not seen this issues before.

DMZ in Hyper-V?
I'm not certain if this is possible but here's what I'm hoping to do.
I have 3 windows servers - a DC, a remote/secondary DC, and an Exchange Server. The exchange server is on the most powerful of the machines and I would like to set up a DMZ for all domain devices. My question is this, can I set up Hyper-V on the current Exchange server, install another server 2012 server on a vm, make that vm act as a DMZ/have the exchange edge server setup? i'm uncertain if this would actually help to secure anything or not, since while the exchange server has 2 nics, it would still be connected from our swich which is directly connected to the modem/wan.
Let me know! Thanks!

Consolidating Snapshots in 2008 R2
I've read several blogs about consolidating snapshots, but haven't settled on a satisfying answer. I have a tree of snapshots under a VM. I want to keep the latest one in the tree (at the bottom) while removing older snapshots to remove virtual
disk files and get back some space. I think I understand that snapshots work a "difference" principle. Can I use Hyper-V manager to delete snapshots in the middle of a tree? Would also appreciate your pointing me to a definitive
reference.

Adding a Hyper-V Server 2008 R2 host (no domain) to a Windows 2012 R2 / System Center Standard 2012 Virtual Machine Manager fabric
I want to add a Hyper-V Server 2008 R2 host (no domain) to a Windows 2012 R2 / System Center Standard 2012 Virtual Machine Manager fabric or host manager not sure.
Should I first have the Hyper-V Server 2008 R2 host (my bare-metal compute) added to the new domain on the Windows 2012 Host machine? And then add the Hyper-V Server core host to be managed by Virtual Machine Manager?
There are 2 physical machines; 1. Hyper-V2008 Server R2 (workgroup) (2 nics) AND 2. Windows Server 2012 R2 Update (Data Center) with System Center R2 2012 Virtual Machine Manager...
I will be also adding another compute host running Hyper-V 2012 R2 Update that I want to add the to System Center host domain and be managed.
Thanks in advance!

Regenerate Snapshots from .avhdx files
I'm getting used to Hyper-V and I come into this situation:
I manually did a backup and a restore of a virtual machine with 1 disk and 2 snapshots. My restored machine has a .vhdx file and 2 .avhdx files and it works well.
Sadly, I can't see my 2 snapshot in the Hyper-V Management Console snapshot list. Even if I can't see those 2 snapshot Hyper-V uses all my 3 disk files (the .vhdx and the 2 .avhdx) giving me the latest updated disk state.
Can I regenerate those 2 snapshot into the list? I saw every snapshot has a .xml file, its possible to regenerate those files?

Win 2012 R2 VM on Win 2008 R2 FOC is backed up with Saved State instead of Snapshot by DPM
I've posted this question a couple of months ago in another forum, but haven't resolved the issue yet. I'm hoping this post could help me troubleshoot this problem once again.
My question is as follows (copied from previous thread):
All my Windows 2012 R2 VMs (that run on a 3-node Windows 2008 R2 Fail-over cluster) are backed up by DPM 2012 R2 (also on Windows 2008 R2) using Saved State instead of Child Partition Snapshot. I've checked the list below (twice), but didn't find anything applicable to these VMs.
- Backup (Volume Snapshot) Integration Service is disabled or not installed.
- The virtual machine has one or more dynamic disks.
- The virtual machine has one or more non-NTFS based volumes.
- The virtual machine Cluster Resource Group in a cluster setup is offline.
- The virtual machine is not in a running state.
- A ShadowStorage assignment of a volume inside the virtual machine is explicitly set to a different volume other than itself.
- An App-V drive is installed on the virtual machine that creates a non-NTFS volume.
I've set the registry setting SystemRestore\ScopeSnapshots to 0 for each VM, and checked the current state with the diskshadow tool (to make sure it wasn't just an erronous datasource text in DPM).
Some more information:
- all Windows 2008 R2 servers on this cluster are backed up by DPM using Child Partition Snapshot
- all VMs (VHDs) are located on an HP Lefthand SAN
I'll appreciate any pointers in finding the root cause of this problem!

How to change the default gateway of 2 hyper-v hosts which are part of a failover cluster
Hi guys,
We recently changed our firewall and I have to change the default gateway, and the secondary DNS entry for all the machines that have static addresses on the network.
When I reached the hyper-v nodes (running Windows 2012 which are part of a failover cluster) I asked myself should I do it individually for each host, or on the cluster. It seems like a simple thing to do but I didn't find a way to do these changes so that I do not cause a problem to the cluster and the VMs
Any advise from you hyper-v gurus ? I'm fairly new to the hyper-v world (comming from vmware).
Thanks

Converged or Non-Converged 2012 R2 Hyper-V Cluster
Here's the scenario.
I have 4 Poweredge R710 Servers each with a total of 12 1Gb NICs connected to 2 phyical switches for redundancy. I have 4 of these reserved for ISCSI storage connectivity.
For the remaining 8 NICs previously in a Server 2008 R2 cluster I would have had the following:
Management Team (2 NICS)
Backup Team (2 NICS)
Hyper-V Team (2 NICS)
Live Migration (1 NIC)
Cluster/CSV (1 NIC)
Now I want to upgrade the Hyper-V cluster to Server 2012 R2 using the same hardware and I have read much on converged networks, smb multichannel and new inbuilt NIC teaming.
I understand there are many different ways to design the networking now and therefore for the networking hardware I have available what are other peoples thoughts on the best design.
Should I keep the old style non-converged networking and have underutilized NICS for much of the time or would a converged network design be able to provide better network performance?
Say for example I create a TEAM of 8 x 1gb NICs and split the Management, Backup, Hyper-V, Live-Mig and Cluster/CSV with vNICS and weighted QOS I would see improvements in the networking?
What are your thoughts?
