3 Windows VM #3

Closed asm76 closed 4 years ago

asm76 commented 10 years ago

Is it possible to run 3 Windows VM with XenGT? If yes, on which hardware?

I only have 256MB available aperture size. dom0 uses half of this. So i can only run 1 Windows VM.

Yes XenGT supports 3 Windows VMs but it then needs BIOS support of configuring 512MB aperture size (each Windows VM needs minimal 128MB aperture).

Thanks Kevin

BIOS on my motherboard support this setting but aperture size is not changed. Can you tell on which motherboard this will work? Have you tested this configuration?

3 windows VM is one of our normal testing configurations. Our machines support aperture setting to 512M in BIOS but they are internal ones not purchased from market.

Can you show output of lspci -vv for VGA controller?

Most mobile Lenovo (HSW-based) systems have a public 512MB aperture sized BIOS. Here is the short list which we know has this BIOS available: T440p

T440

T540p

T540

X240

X1-x
