[Solved] Cannot run 8.1 or xp VMs on W10 host

[danielsuarez369]

Hello there! Been trying to run VMs but keep getting errors, including the logs

Disable Hyper-v (yes it is). Please search for previous discussions.

I see in your log that windows hypervisor platform is available, so even with hyper-v enabled this should work.

Have you had any luck? I'm in a similar boat with getting VMs to start using WHP support that was added in 6.0.

I'm having issues similar to virtualbox tracker's ticket/18588 which seems to be what you're experiencing.

This should work with WHV and Hyper-V enabled.

I tried to run: Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

But get this error: cdn.discordapp(DOT)com/attachments/421767826030854146/584744509657841704/unknown.png

Sorry for bypassing the rule but I couldn't even post the photo as an attachment because it's too big

Also tried to run: dism.exe /Online /Disable-Feature:Microsoft-Hyper-V-All

But got that error

Have a read of a related topic: viewtopic.php?f=1&t=62339 (second post).

Also, I see you're using a recent "insider edition" of Win10. For all I know that breaks something. I expect this will receive attention if the problem continues into an official release.

Fixed!

For anyone who has this issue, was getting:

Failed to open a session for the virtual machine Windows XP.

Call to WHvSetupPartition failed: ERROR_SUCCESS (Last=0xc000000d/87) (VERR_NEM_VM_CREATE_FAILED).

Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap

Look in the "Control Panel" » "Programs and Features" » "Turn Windows features on or off", and make sure that the none of the following are active:

• Hyper-V
• Virtual Machine Platform
• Windows Hypervisor Platform
• Windows Sandbox

then run bcdedit /set hypervisorlaunchtype off
then reboot

Glad you got it going. Marking as [Solved].

Just for completion and any future reader, here's what my typical answer looks like:

Look in the "Control Panel" » "Programs and Features" » "Turn Windows features on or off", and make sure that the none of the following are active:

• Application Guard
• Credential Guard
• Device Guard
• <any> * Guard
• Containers
• Hyper-V
• Virtual Machine Platform
• Windows Hypervisor Platform
• Windows Sandbox

If VirtualBox is running without Hyper-V enabled, where proper, hardware virtualization is actually available, then the standard virtualization icon () would show.

If that doesn't work, enter the following command:

• 
  bcdedit /set hypervisorlaunchtype off

followed by a cold boot, i.e. shut down the computer, pull the power plug for 10", reboot.
