VM uses EFI boot and SVGA with defaults as display adapter, I attached the vmx file too. Thanks! I see. I have a patch out that fixes it, but in general I think those vm's with 16mb for graphics are very risky and I'd suggest bumping them to at least 32mb. The vram portion can stay at 16mb, but the graphicsMemoryKB can be safely set to fourth or even half of memsize (in your config 256mb or even 512mb), which will make the vm's a lot safer and allow actual ui usage because with console being pinned we just don't have a lot of wiggle room otherwise and we just can't migrate pinned framebuffers. The patch that "regressed" this makes dumb buffers surface that actually respect pinning, but as long as you don't have gpu host side things will be ok. Otherwise we can't make a config with 16mb of available graphics memory and graphics acceleration work. z
