NARATIVE
after reading several posts on several forums and blogs related to pci passthrough, unraid and proxmox
from my understanding
1. passing through an onboard graphic card is a pain in the hax
2. passing through an the main and only graphic card is a pain in the hax
3. passing through an intel graphic card is a pain in the hax
The questions
1. someone succeed to passthrough an onboard intel graphic card ?
2. could someone confirm than I could easily resolve this by buying an graphic card ?
2.1 which one is the most recommended ? (my goal is to play movies with KODI)
For others who would like to help me to do deeper, here is my story...
On a gigabyte z170 with a Intel Skylake Processor
I'm able to use the on-board Intel HD Audio into a VM but struggle to pass the on-board graphic card.
IOMMU is configured and works with the sound, if I boot up a live Linux MX and play a youtube I could ear it.
When I try to pass-through the graphic card, I see a glitch, the monitor receive a signal but, after a while it fall a sleep because of no activity.
I still able to stop and restart the VM and access the host via ssh.
#00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics 530 [8086:1912] (rev 06)
Here my configurations
cat /etc/kernel/cmdline
but I also tried without the
and obviouly reload UEFI config with
cat /etc/modules
the last part was used while I was using KVM on with Ubuntu
as usual I also tried with
and run
the configuration of my VM
cat /etc/pve/qemu-server/100.conf
as you can probably deduce
I tried for
- the hostpci0
- the SeaBIOS and UEFI BIOS
- several display from default to none and by adding more memory
- with a machine q35 and i440fx
So as you could tell any idea I'll be happy to try it
thank for you reading and your help
