[Xen-devel] Bug Xen-4.4.0-RC6 with Hyper-V on Server 2012 R2.

[Valentin Meriel <valentin.meriel@xxxxxxxxx>]

Hello,

I have a probleme with Xen-4.4.0-rc6.

I try to use Hyper-V on Xen 4.4.0, because of none sucess with KVM and Qemu.
I want to because i want to passthrough one (or more) VGA card to Hyper-V to test remoteFX (just for test if it work).

So on KVM-Qemu i can not install Hyper-V on Windows Server 2012 R2 because of an allready runnig Hypervisor.
On Xen i have the same "error" but if i add :
    hap = 1
    nestedhvm = 1
    cpuid = ['0x1:ecx=0xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx']
to my config file, i can install Hyper-V role, but when the VM restart it does not work, the Vm stuck on the first screen with the Windows logo.

To make the VM start again i have to comment out cpuid = ['0x1:ecx=0xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'] and after the VM can start, but when i whant
to start the L2 VM (the Hyper-V's VM) Hyper-V cant because one of this service is not started (or something like that).

Have you an idea ? Because in the wiki it's say it's work.

Thanks, and sorry for the my bad english, i'm french ^^.
