virgl 3d acceleration support?

[paulmorabi]

Hi,

I'm trying to set up a Linux VM to use the virgl 3d accelerated graphics driver. My VM config is:

agent: 1
bootdisk: scsi0
cores: 8
cpu: host,flags=+pcid
efidisk0: shared:vm-103-disk-1,size=128K
ide2: local:iso/linuxmint-19.1-cinnamon-64bit.iso,media=cdrom,size=1927648K
machine: q35
memory: 8192
name: Linux
net0: virtio=A2:54:6F:DC:1C:0F,bridge=vmbr0,firewall=1
numa: 1
ostype: l26
scsi0: shared:vm-103-disk-0,size=256G
scsihw: virtio-scsi-single
smbios1: uuid=744d2587-30f2-45b4-b9d4-c12bd4354771
sockets: 1
vga: virtio,memory=512
vmgenid: 806c794f-04b5-4767-bbe9-d7505c63fe74

When I boot into Linux Mint it gives a message about using software graphics drivers and in dmesg there is the following line "Virgl 3d acceleration not supported by host". I've tried also Manajro Linux and it just hangs.

I'm using the latest Proxmox 5.4-6.

Any ideas would be very appreciated!

No solution yet?

our qemu is not compiled with virgl support, so without recompiling qemu this will not work
also afaik virgl does only work with a local gtk/spice screen not over the network with vnc...

Can you add to your roadmap compiling qemu with virgl?
I would like to use spice with it, yes.
Thanks.

I would like to use spice with it, yes.

maybe i did not express myself clearly... afaik even with spice it does not work over the network only on the local machine
so for a server os like Proxmox VE this is not very useful, but you can open an enhancement request[0] for it, maybe someday it will
be possible to use over the network i guess then it would make sense for us.
