Windows 10 guest results in black screen after trying to boot

Post by cdangerdouglas »

I have windows 10 64bit guest that has been working fin on my windows 10 host 64bit 32 gb ram. I enabled hyper-v to experiment with docker but ultimately had to disable in an effort to get my VM working again. even after disabling, I am unable to get my VM to boot properly. The VM just restarts a bunch of times, sometimes shows the windows logo and ultimately ends in a black screen.

00:00:01.317628 Guest OS type: 'Windows10_64'
00:00:01.332871 NumCPUs <integer> = 0x0000000000000001 (1)
Paravirtualization:
00:00:01.357993 GIM: Using provider 'KVM' (Implementation version: 0)
Windows 10 likes 2 processors and does not speak KVM.

Set to two processors, and set System > Acceleration > Paravirtualization to Hyper-V. (this paravirtualization is a comm channel between the hypervisor and modern Virtualization-aware OS's. Setting it to Hyper-V is not the Virtualbox-killing Hyper-V.)
