All possible values of Get-VM State property
Few questions related to the "State" of the VM:
1) Get-VM has a bunch of properties, one of them being the "State" property which gives the running state of the VM I guess. I have seen various values for State - Off, Running, Saved, OffCritical, RunningCritical. I have a use-case wherein I have to return something based on this state, so I need to know all possible values of the State. I was trying to find it online but didn't find anything. Would be great if someone can let me know all possible values of the "State" property.
2) Also there is a gwmi query which retrieves the VM information - Msvm_ComputerSystem. In the output of that query, there is a EnabledState field, which returns various values related to the state of the VM. I wanted to know how different it is from the"State" returned by Get-VM. Can they be used interchangeable? I have observed that when the "State" from Get-VM is OffCritical, the "EnabledState" from the gwmi query is "Off".
3) Also, what is the difference from the value obtained from Get-VM and gwmi Msvm_ComputerSystem?
Thanks for your help in advance!

Hyper-V Slow performance + GPU?
Hi,
I'm using Hyper-V to install multiple OS and use them, not all at the same time but when I need to. I'm currently using Windows 10 PRO 64 bit as the host.
The problem is that I have successfully installed windows 7 professional but the performance is really slow and I cannot go above 1024x768 resolution despite having a 4K TV, is there any solution to this problem?
I'm also curious if I can get my GPU working on the virtual machine, I know there's RemoteFX but when I configured it, Windows 7 (VM) tried to install a driver on reboot then it failed to install.
Help, please!

Hyper-V VM Generation 2 - How to boot from .ISO
Hi guys,
Server OS: Windows Server 2012 R2
I have a VM Gen2 with following settings:
I can boot fine from the same .iso from a Gen1 VM so the .iso is bootable.
I know that the Gen2 VM uses SCSI instead of IDE, but I have no clue regarding how to boot from the .iso..
Any ideas?
Thanks in advance!
Best regards,

2012 R2 Hyper-V VM Disk 2 has been surprise removed | An error was detected on device \Device\Harddisk2\DR2 during a paging operation
I have been scouring the internet for over a week now, and I cannot figure this one out. Some background... I am retiring an old physical file share server, and I am creating a new 2012 R2 VM on a 2012R2 DataCenter Core Hyper-V host. Creating the VM went without issue. It is configured as follows:
8GB RAM
4 CPU Cores
72GB system drive (C:\)
2TB data drive (D:\)
12GB page file drive (Z:\)
I have about 1.8TB of data to copy over from a physical box, so I am using RoboCopy. I have gotten about 1.5TB of data over, then the new VM's data drive (D:\) disappears and the copy fails. The disk no longer appears in Windows Explorer or diskmgmt.msc. The even log shows many event IDs 153 (The IO operation at logical block address 0x*** for Disk 2 was retried) and event IDs 51 (An error was detected on device \Device\Harddisk2\DR2 during a paging operation, and the last event when the drive disappears is a single Event ID 157 (Disk 2 has been surprise removed).
After racking my head over this for several days, I deleted the VHDX for the 2TB data drive, created a new one, and started the data copy all over... same issue. I completely deleted the VM and all files, reinstalled on new VHDX drives... same issue.
This leads me to think it is an issue with the Hyper-V host, but there are no event IDs pertaining to this, and the other 53VMs are running without issue.
I would SINCERELY appreciate any help with this.
Sorry for huge post, but thank you in advance!

Shared VHDX, Additional Storage, Guest Cluster.
Hey Guys,
I have the following setup:
- 1x VM, created using Failover Cluster Manager
- 1x LUN presented to both hosts as the boot drive
- 1x Additional LUN also presented to both hosts. this is the data drive.
- 2x VM hosts. (Windows 2012 R2), VM can be migrated from one host to another without issue.
The boot drive LUN is currently running via iSCSI and presented to both my VM hosts. I created a machine in FCM and have successfully attached the VM via (Cluster Shared Volumes) 1x Volume per VM.
However I would like to add an additional CSV to the same VM so that I have a total of 2 separate LUNs attached to the one single VM. I am unable to figure out how to add the additional LUN
Also, do shared vhdx files only work when they are connected to a guest cluster? or do they also work when they are directly attached to a VM from the VM Host?
Thanks,
Robert

The process has not been granted access rights to the parent virtual hard disk
While restoring VMs I receive the following error in event logs:
The chain of virtual hard disks is inaccessible. The process has not been granted access rights to the parent virtual hard disk for the differencing disk.
I am the admin. The machines are messed up. Of course they had checkpoints and of course it was a bad idea (from today's perspective). Now when restoring them I feel like catching all Pokemons from the MSDN error codes list. Please advise how to proceed with this particular one.

Changing Path of initial replication snapshot
Hi All,
we've got a huge VM which we want to replicate to another Hyper-V host (at least we are trying to switch to another hardware with minimum downtime).
Problem now is that the snapshot created by initial replication gets too big during the first copy. So we've set up another drive within the hyper-v host which has enough space but I'm not able to change the path of this initial snapshot.
Anyone knows what to do?

Windows 10 Build 10240 Managing Hyper-V on 2012 R2 Datacenter Cannot Connect
So, we have a total of six Hyper-V servers in our environment. All six were installed from the same Server 2012 R2 Datacenter ISO. I have been managing these from my Windows 8.1 machine with no issues. I got ahold of Windows 10 build 10240, and I am running into an issue connecting to the servers now.
The strange thing is that I CAN connect to one of them. I cannot figure out what is different on this one server from the other five. Windows updates maybe? I migrated all the VMs off one of the servers I cannot manage remotely, performed all Windows Updates, and I still cannot connect to it.
I am reading that Windows 10 should be backward-compatible with managing Hyper-V on 2012, but on connection, it appears a WMI namespace is missing that the Windows 10 tools are trying to connect to.
I am not trying to use alternate credentials (I read this will NOT work from 10 to 2012 R2). Any ideas why this is not working? Several Google searches have not told me anything so far. I realize Windows 10 has not officially been released yet, but a few of us are testing the waters for compatibility issues.
I would appreciate any help anybody can offer.

Guest VM cannot ping other VMs on other node of the cluster
Hi,
my Exchange 2016 VM has a strange behavior in network communication. I have two node cluster (2012 r2). From the Exchange VM I can ping (and do other net communication) to any other physical computer on the network and to the VMs on the same host. But I can´t
communicate to the VMs running on the second node of the cluster. When the VM is running on the same host, it is ok, but when the same VM is migrated to the second host, it losts connection with the Exchange VM. I am really banging my head against a wall,
because I can’t find any reason, why this one VM showing this strange behavior. Other VMs are OK, neither of them suffers with this disfunction, even though they are configured in the same way (the same configuration of the NIC, same Windows Firewall config,
etc.)
Can you please give me some hit points what could be the source of this problem? Nothing strange in the logs (Exchange VM or hosts). Thanks.

Not enough memory to start _ Allow Virtual machines to span NUMA nodes is off
Occasionally I am having trouble starting a VM.
Key is one VM I want to allocate 30Gb of ram to (better would be 32GB but I can't get this to work) even though this is the first VM to start.
Server had two physical CPUs (each 12 cores). Server had 64Gb RAM
The other virtual machines are set to dynamic memory and start later without issue.
Any advice would be great.
Note span Numa is deliberately off.

VMs will not start after unrequested update to v1607 on W10.
I had a running VM (W10) on my W10 Pro x64 (v1511) when the Anniversary update to V1607 started without my permission or knowledge. When I returned to my system, I found a saved VM but it would not start, so I deleted it and clicked upgrade the VM
but it still would not start. The error message says "'VMname' failed to start worker process". It also showed error code 0x8007042B.
Finding some hints via searching I tried removing the Virtual Switch and creating a new one, turning the Hyper-V feature off/on, creating new VMs. All to no avail.
I hope someone can get me running again without removing v1607. Thanks and enjoy, John.

Rebuilding Hyper-V
I'm running Hyper-V on a 2012 R2 server.
I need to rebuild this 2012 R2 server fresh and join to a new AD domain but the host name and IP will remain the same.
What would be the best way to restore the Hyper-V configurations and the VMs?
Do I just backup and restore the Virtual_Hard_Disks (has all the VMs) and the Configuration_Files\Virtual Machines folders then in Hyper-V settings, re-point the Virtual Hard Disks and Virtual Machines to the restored location?
And is there a way to backup and restore any other settings hyper-v related settings such as the Virtual Switch settings?
Thanks
