Can Hyper-V Span Across Different Chipsets RE: Replica DR/BCP?
Hey Forum Users:
If I plan on moving my entire architecture from VMware/Win2008-2003 to Hyper-V/2012-2008 is it possible to have different chipsets? In the best of all worlds the answer is yes but think it's no.
One datacenter has AMD servers while the other has Intel. The goal is to flatten out the network, move to a single domain and use each datacenter as a DR site for the other (and vice versa).
Whether I spend another $20K hinges on the efficacy of cross-processor use.
Thanks, IMSIT

Windows Server 2012 Failover Cluster Virtual Fibre Channel Adapter Live Migration Error
Hello,
I've got a 3 node cluster running Windows Server 2012 on HS22 IBM Blades with 8GbFC HBA's connecting to a XIV SAN. I am trying to get the virtual HBA's working in Hyper-V Guest running Windows 2008 R2.
I first created 2 virtual SAN Switches one connected to each port on my physical HBA (each physical port connects to a separate fabric).
I add two Virtual HBA's in my Guest, one to each VSAN Switch.
When I go to Zone the HBA's I only see side A of the virtual HBA's not both A and B. On each fabric I should see two (A and B) WWPN but I only see one.
I can add disk and everything works, however when I go to Live migrate I get the following error due to side B not being zoned.
Live migration of 'Virtual Machine Win2012_01' failed.Virtual machine migration operation for 'Win2012_01' failed at migration destination 'hv-cl07-c2'. (Virtual machine ID 2CE90D02-083C-4012-ACA1-BE8D35EFCA33)

Has anyone see this issue yet?

Where to Keep HA VHDs?
I am currently running Hyper-V on 2 identical hosts. I would like to set them up so that if a VM or Host fails then it would automatically start on the other available host. I had a question on where to store the VHDs for the VMs and how to access them.
They are currently on a LUN which I have mapped via iSCSI to "D" on Host1. Would I be better off converting it to a CSV and storing/sharing the VHD files from there?

VDI infrastructure
I have been asked to come up with some solutions for Desktop visualization within a school environment. I though this would be a pretty straight forward task and it would be between Vmware, Citrix or Microsoft.. But I cant seem to find the information
I am looking for.
The current setup is 2 servers running VMware ESXI & San for all their current servers.
My though thought was looking down the Microsoft and Hyper-V route as they already have the licenses in place for the Microsoft products.
They have about a 1000 computers and 200 probably being used at any one time.
They will need two groups; Students which use a shared VDI (Wiped every log off) and a Teachers which do not get wiped.
So I guess my question is does anyone have any experience with a similar setup?, Can I do all of this with Server 2008 & Hyper-v? and whats the best way to work out server / storage requirements?

Losing pings only within a Hyper-V cluster.
Good day.
We are experiencing an issue on our VMM based private cloud where pings are failing only for VMs running within the private cloud. We can ping servers on the rest of our network with no apparent issues. We can even ping the cluster nodes that host the private cloud VMs without issues. When we try to ping the VMs though we note between 1%-3% in missed pings.
We've tried a couple of tests to try and isolate this to see if it could be related to our older, non-IPv6 aware, hardware switches but have not seen any significant change in the behavior. One test we attempted was to take the NIC connections for one of the nodes that are connected to the vSwitch that the VMs are running on and place those two connections on a different physical switch to see if this was some kind of address space issue from the switch perspective. This test resulted in no change to the behavior and the ping loss of 1-3% continued.
At this point we suspect that this is a configuration issue on our part, but we're not having much luck figuring out how to best troubleshoot this issue. Are there any statistics we should be looking at from the VM, vSwitch, or Hyper-V level that might help us better identify the root cause of this issue?
We are running an 8 node Windows 2008 R2 SP1 cluster with several post SP1 patches loaded on it. We are also running SCVMM 2012 Update 2. The VM networks are running off of a pair of teamed Broadcom NICs on each host with a separate set of teamed NICs for all of our iSCSI and Cluster network.
Any input or thoughts would be appreciated.

Hyper-V Server 2008 R2 + WMF 3.0?
Can Windows Management Framework 3.0 (with Powershell 3.0) run on Hyper-V Server 2008 R2 SP1?
In case there is any confusion, I am asking about the free "core" version called Hyper-v Server, not Server 2008 with the Hyper-V role installed.

Hyper-V MMC Crashes on right-clik
This just started happening today and I have no idea why. When I go into the Hyper-V MMC snap-in and right-click any of the virtual machines, the MMC crashes (VM's still run fine but I have to restart the MMC). If I left click to select a machine and then use the options on the right side everything is fine. This is the only snap-in that crashes for me. Has anyone experienced this? I've looked at the event log and is entirely useless.
This is Windows Server 2008 R2 running as a bootable VHD (I've been doing this for over a year with no problems). This also happened to a co-worker today (and it's constant - it never works anymore). But we are using different Win2k8R2 builds so I don't see any commonalities (different vm's, different machine configs, different hardware, etc.).
Any thoughts would be appreciated. It's annoying.
Thanks!

Physical disk option grayed out after adding SAS HBA and Tape drive---Hyper-V on 2008 R2 Standard
We have recently setup a new Windows 2008 R2 Standard server with the Hyper-V role. We have a 8 drives connected to the onboard SAS all of which are offline in disk management. They are assigned as physical disks to one VM running Ubuntu. Everything has
been running fine until we added a SAS HBA to the system. This is needed for our tape drive to attach to this machine. When Windows boots, the card and tape drive is seen no problem. The disks are still listed in disk management in their offline state. The
problem is, we cannot start the VM anymore because the option to use the physical disk is grayed out. On the virtual SCSI controller that is attached to the VM, it shows the disks, but it says "in use". If you remove the virtual SCSI controller and add a new
one, the physical disk option is grayed out. Anyone have any ideas on this? Thanks in advance.

Using Hyper-V replica between two primary sites as a DR to each other
Hi there, this is a Hyper-V planning question. I recently learned about Replicas and am excited about using it for clients looking for solid DR. Here is my scenario:
Site1:
Hyper-V Cluster for local users
Running: DC, SQL, FS, etc.
Site2:
Hyper-V Cluster for local users
Running: DC, SQL, FS, etc.
Is it possible for us to have each site serve as a DR site for each other so that if Site A failed, site B would handle DC, SQL, FS from Site A and DC, SQL, FS from Site B? I understand that I could use AD replication for the DC and DFS for the FS, but leaving that out, would this scenario work, or do I need a dedicated replica host?

Hyper-V 2012 NIC Driver
Hello,
I have installed Hyper-V 2012 and get the message "No Active Network Adapters Found". The system has a common Intel Pro1000 card. I've tried installing the driver using pnputil -i -a driver_file.inf, but after a reboot I get the same message. I've also tried installing the driver with devcon. devcon find shows my Ethernet adapter and the hardware ID matches what is in the inf file, but fails to install the driver. ESXi and XenServer both "just worked" on this hardware, though I'd like to test Hyper-V as I hear it has a better feature set. Thanks in advance!

Will Microsoft support us if we install Windows 2012 on a non "Certified" hardware platform?
I have 12 IBM HS21 blades and I have considered installing Windows 2012 Hyper-v standalone on them. I notice they are not under the hardware compatibility list as certified, but if I were able to install Windows 2012 successfully on them will they be supported
if I ever had an issue?

RAID performance issues, reconfig suggestions wanted
Hello all,
We have built a total of 6 boxes as our private cloud infrastructure, all of them running Server 2008 R2 and Hyper-V. 3 of these boxes are located at our primary office and use a combination of local storage and iSCSI LUNs utilizing Microsoft iSCSI Target software from our NAS. Those 3 boxes have no performance issues whatsoever and house the great majority of the ~250 VMs currently provisioned in our VMM private cloud.
Recently I built another box for a remote office, similar hardware specs with the only difference being all of the data/VHDs would be stored on local storage. Due to the onboard RAID controller not supporting a suitable stripe size for Hyper-V, I resorted to using Windows software RAID5 for our 5x2TB disks. I know RAID5 is far from hyper-v best practices, and I have passed that information along to my boss but he believes it is the best bang for the buck. I had trouble copying our existing VHDs to the array the first night I was there working on it, it seems as soon as I started the data transfer the disk I/O went through the roof and the whole machine would lock up, explorer.exe would crash. After wrestling with that for awhile, I discovered if I just left it going it would eventually finish the data transfer so that is what I did. The same problem seems to be occurring once we cross the 10 running VMs threshold. Trying to create another VM can cause the whole machine to lock up.
The disk configuration is as follows:
1x 1TB 7200RPM WD RE4 non-raid for OS
5x 2TB 7200RPM WD RE4 - Software RAID5, 128k stripe size I believe.
We are having the same problem with another box we recently built with the exact same specs. With 10 or more VMs running simultaneously, the box becomes unusable and all of the running VMs become very slow.
I'm trying to find hard data to show my boss that we would gain substantially better performance by going to a different RAID configuration. What do you guys think? RAID 10? JBOD? What's the best way to remedy this problem.

Hyper-V Server 2012 BSODs when teamed NIC is used VM networking
I have Hyper-V Server 2012 installed on a Sun Blade X6250 Server that has 2 NICs 1Gbps each.
Using Powershell, I configured the 2 NICs to do NIC teaming.
- Load Balancing algorithm : IPAddresses
- Teaming Mode: Switch Independent
Hyper-V server now shows only 1 NIC so I set a static IP to it.
Then I go to my Windows 8 machine with Hyper-V Manager and go to Virtual Switch Manager. When Creating a New Virtual Switch, I select External Network and the Microsoft Network Adapter Multiplexor Driver.
When I click apply the Hyper-V server BSODs and reboots.
Does anyone have an idea how to use a teamed NIC as the network for Hyper-V 2012 VMs? Does Hyper-V Server 2012 allow this?
Thanks.

Having problems with Hyper-V 3.0 + VMM sandbox
Hello,
I'm a long-time user of ESXi + vCenter and I'm looking to migrate to Hyper-V 3.0 + VMM to replace it. At least I think I am. I've spent the last several days trying to set up a sandbox to validate how things will work, and it's been slow going. I'm hoping to hear from others that have made this migration that can point out any gotchas or surprises that they ran into. I'll start things off with a few that I've already hit:
- While VMM 2012 runs perfectly fine on Server 2008 R2 SP1, VMM 2012 SP1 Beta will not. It requires Server 2012 Standard or Datacenter. This is a huge surprise and blow for my budgeting purposes: we had a spare license of Server 2008 R2, but now I'll have to buy another copy of Server 2012. (Who in the world changes OS requirements when they introduce a freakin' service pack??)
- In vCenter, there are some simple, but very useful performance analytics available at the host level. So far I haven't found anything like that. Can anyone point me in the right direction here?
- While Microsoft uses the term System Center a lot, there isn't really a System Center product. There's a pile of products that don't seem to be integrated in any way, that they collectively refer to as System Center. Whatever you do, DO NOT try to install them together. Just go install the ones you need, like VMM.
- I still haven't been able to get my first VM deployed using VMM. I think it might be due to how I've set up my sandbox: I've basically built a bunch of VMs using a Windows 8 box running Hyper-V Manager (a DC, a VMM server, and 2 Hyper-V hosts) and then I'm trying to deploy a VM from inside this, and it doesn't seem to like it. Does anyone have a guide on how to create a lab environment with a single box? Or, better yet, an online lab that is already set up?
Thanks in advance for any help. I realize this stuff is very, very new, so hopefully we can all learn together on how it works. Given that Hyper-V is feature-parity with ESXi plus, with Datacenter Edition, you can have unlimited Server 2012 VMs running on it, the value proposition is huge!

Mapping Physical Networks on Hyper V
I have Hyper V 2008 7.6.10, and I have just created 5 virtual machines which I would like to provide 3 different networks to them. WAN, LAN and DMZ.
The Hyper V original was installed with one NIC "LAN" but now I would like it to show the 3 of these NICs which are physically connected to the HYPER-V already.
I have tried to browse to the Hyper V Virtual Network management console and click "Add External" then choose the Physical LAN but that would give me error setup installation all the time.
I haven't done this before and I would appreciate how to do this!
Thanks

Reduce Memory of Pooled Virtual Machines from 2048 MB to 1024 MB
I setup 15 Virtual Machines in a VDI setup on Windows Server 2012 Data Center and the Setup changed the memory of the virtual machines to 2048 MB for each Virtual Machine. I don't need this memory and was wondering why it set the memory and does not use
Dynamic Memory. These machines barely need 1024 MB each. Can I safely change this or not?

VM won't start because SCSI Physical drive Not found
I added a SATA hard drive to the host system, set it offline, and attached it to the VM SCSI Controller as a Physical hard disk. After starting the VM, I assigned a drive letter and copied files from the hard drive, then shut down the VM and the host, then removed the hard drive from the host. Now the VM will not start with error: Synthetic SCSI Controller (....): Failed to restore with Error 'The system cannot find the file specified'.
In the VM Settings, the missing Hard Drive is listed as Physical drive Not found. I cannot find any way to delete this missing hard drive from the SCSI controller - the Remove button is grayed out.

Speed up he hyper-v replication initial transfer
I have started the vm replication for a week but it is still at 80% replicating. The vhdx file is 69g and the gfgfg.hrl file is 39g. I know it is replicating because I can see the hrl.tmp file is getting bigger. My question is if it is ok just copy the
gfgfg.hrl file to an external hd and dhl to my replica site; paste over to the existing hrl.tmp file. This way is faster and save my bandwidth. Thanks
