The guests will hang on to the existing memory until either the guest is rebooted or ballooning takes effect and the host "steals" back some of the RAM (which shows as used on the guest). This is likely because the OS doesn't respond as well to sudden "missing" RAM (similar to hot-add being a thing but removal requiring a reboot).

What takes the VM's offline during a validation is testing the storage system. You can skip that part of the validation. Also, you aren't required to validate a cluster when a host is joined. If you want Microsoft to support you, they will ask you for a validation report. But you don't need long term support from them for your temporary solution.

Set the VLAN on the NIC in the VM settings in Hyper-V manager and set the switch port to mode trunk with at least that VLAN allowed. Remember that you won't be able to route between VLANs with the same subnet on them, so you will need to change IP schemes if they need to communicate at layer 3 but be separated at layer 2.

Looks like you set the share permissions, but not the NTFS permissions. You need to do both.

Adian Finn explains the limitations of guest clusters quite well here: http://www.aidanfinn.com/?p=14936 The answer is no, as of Server 2012R2, you cannot live storage migrate the guest shared VHDX. You can move everything else still, but not the shared one. You also cant expand the shared drive online or use Hyper-V replica. It makes sense really - ...

Yes- you can use RBAC to assign the linux VM to a scope, and then apply the necessary roles to the office staff for that scope.

On the host, you have to create a second virtual network that contains your iSCSI NIC's. Then you can add a NIC to the guest attached to that network. That gives you access to the iSCSI network inside the guest. However, Hyper-V does not support booting guests directly from iSCSI. You have to chainload in to iPXE or something similar. Hopefully you already ...

You should not experience any problems moving between different processor types in a scenario where you stop and start the VM. (Such as an export and import.) If these are cluster nodes and the cluster nodes had different types of processors in them, and you wanted to move (but still not live migrate) the VM from one node to the other, you'd need to ...

Looks like credssp configuration issue. 1st workaround: Put the following in a .reg file and add it to the registry: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\Credssp\PolicyDefaults] [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\Credssp\PolicyDefaults\AllowDefaultCredentials] "Hyper-V"="Microsoft Virtual Console Service/*" ...

First of all you won't be able to access a CSV from the 2008 R2 cluster and the 2012 R2 cluster at the same time. Second, you should consider using SCVMM 2012 R2 (System Center Virtual Machine Manager) to migrate your virtual machines between the clusters. SCVMM will be able to move the VMs from the 2008 R2 cluster CSVs to the 2012 R2 cluster CSVs and ...

1.I know that Hyper-v Would be installed on the primary drive on the server and would be running with Windows server installed on it. What would be a good method to do a backup of the file server that is running virtualization? You really don't want to be running anything else on the physical server but Hyper-V. You would instead be creating a virtual ...

You need to create a new internal network in Hyper-V-settings for virtual switches. A corresponding virtual NIC will show up in your Hyper-V-Hosts network-settings. On your physical connection, you can then share your internet connection with that virtual NIC using normal internet connection sharing. You should be aware that this will enable a second ...

If you want to merge the snapshots and retain the snapshot tree, one way to do it would be to export the virtual machine, delete the snapshot subtree, and then import the exported virtual machine as a new virtual machine. Now the original virtual machine will have all of the snapshots merged into the parent VHD(X) and the exported/imported virtual machine ...

One thing I'll point out: when you turn off NUMA, what you are saying is "only use the RAM that is directly connected to yourself" - so that's why you're only seeing half when you turn that off. Otherwise, you gave a lot of information, but not the information we really need to help you with this. I will say looking at your guest information, you do have ...

The answer depends on what you mean by "use this new template." There are two possible interpretations: Deploy new VMs based on the changes that I made to the template. See the changes to the template in already deployed, older VMs. The answer to the first question is that you need to merge the last .avhdx file from the VM where you applied the changes ...

What would be a good method to do a backup of the file server that is running virtualization? Assuming that you actually mean your file server is a virtual machine, you have two options. Treat the FS VM at if it was physical, and back the contents of the VM using the standard backup tools. Windows Backup, or your favorite 3rd party software. Backup ...

Add the target account credentials to the Windows Credential Manager from the command line and try reconnecting: cmdkey /add:TARGET /user:TARGET\USER /pass Where TARGET is the remote Hyper-V host name and USER is the username added as an Administrator to the Hyper-V server. As an aside, after having struggled with this configuration myself, I highly ...
