qemu 1.5.x / 1.6.x source deb

[achristiansen]

Hello Support Forum.

i was wondering if it would be possible to profide proxmox working qemu source packges for version 1.5 or 1.6 of qemu.

The reason for this inquiry is having proxmox to be able to passthrough VGA hardware to VM's. For backgroud info see this page: https://bbs.archlinux.org/viewtopic.php?id=162768.

Thank you. Axel

We need to redo our backup patches for new qemu, because parts of our patches are now merged (but only parts). This is already on our TODO list, but will take some time (maybe qemu 1.7).

running the 3.9 kernel.org was pretty straight forward. KVM and GUI do work but many other things like vz are broken. This is eperimental anyway. I was able to build qemu 1.5.2 in the pve-qemu-kvm source deb (qemu 1.4.2) while had to disbale most of the patches.

kvm early exited: "-id: invalid option". Seems caused because of missing fairsched.diff patch.

also, proxmox code don't have vfio support, so not sure it'll work out of the box, even with a 3.9 kernel.

What i have understand so fare is, that proxmox do not really need to know about vfio. It will turn out what eventually needs to be modified in proxmox.

I am in the progess of reapplying patches to qemu 1.5.2 until proxmox will start it hopefully. Momentarily i got stock with the vnc x509 cert stuff.

archlinux blog say that we need to manage this kind of device

"-device vfio-pci,host=07:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on"

but you can use "args: -device vfio-pci,host=07:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on" in vm config file if you want.
