Hi
I’m trying to build a working machine based on the “QubesOS” operating system my goal is to work in 3D and Render
My Hardware:
- CPU AMD1800x
- MB crosshair VI hero
- GPU GTX980 and 780TI
My question:
it is possible to pass 2 GPUs to the same VM?
I have to buy another GPU for the QubesOS system, some recommendation?
(low cost 2GB or 3GB for an HDMI monitor 1920x1080)
VM Creation Method and Problems: (passGTX780ti for test)
qvm-create --class StandaloneVM --label red --property virt_mode=hvm win7test
qvm-prefs win7test memory 4096
qvm-prefs win7test maxmem 4096
qvm-prefs win7test kernel ‘’
qvm-volume extend win7test:root 50g
qvm-prefs win7test debug true
qvm-features win7test video-model cirrus
qvm-start --cdrom=vmDownloads:/home/user/isos/w7.iso win7test
->restart
qvm-start win7test
->Windows is installed and working
qvm-prefs win7test memory 2048
qvm-prefs win7test maxmem 2048
qvm-features --unset win7test video-model
qvm-prefs win7test qrexec_timeout 300
qvm-prefs win7test debug false
in dom0:
lspci
0b:00.0 (gtx780tivga)
0b:00.1 (gtx780ti audio)
in /etc/default/grub
add:
GRUB_CMDLINE_LINUX="… rd.qubes.hide_pci=0b:00.0,0b:00.1 modprobe=xen-pciback.passthrough=1 xen-pciback.permissive"
GRUB_CMDLINE_XEN_DEFAULT="… dom0_mem=min:1024M dom0_mem=max:4096M"
update grub:
grub2-mkconfig -o /boot/grub2/grub.cfg
reboot
Add in GUI
VM-win7test -> gtx780ti vga and audio
-> qvm-start win7test
Problems:
windows detect GPU
I install software rendering no gpu detect and no CUDA
i Install new Nvidia driver i have erro43
this was my experience for now,
Thanks in advance
