QEMU 9.2 available on pvetest and pve-no-subscription as of now

[t.lamprecht]

Hello
Is there a need to reboot ? PVE or vm or none ?
Thanks

You need to fully restart the VMs (not just a reboot from inside the VM OS) or live-migrate them to another host that eas already updated so that the VM uses the newer QEMU executable that includes the fix.

AFAIK, you need to fully shutdown the VM (not reboot) & restart.
Please note that as of last night, the updated pve-qemu-kvm=9.2.0-3 appears available in the regular pve-no-subscription repo.

Hi guys,

are you sure it's fixed in `pve-qemu-kvm=9.2.0-3` ?

I have home assistant VM, doing mostly nothing, idling. (2 vCPU)

- On my older `pve-qemu-kvm=9.0.2-5` it was idling on `0.6-1.2%`
- After upgrade to `pve-qemu-kvm=9.2.0-2` idle is `2.5-3%`
- With `pve-qemu-kvm=9.2.0-2` and `qm set {id} --args '-machine hpet=off'` idle back to `0.6-1.2%`
- After upgrade to `pve-qemu-kvm=9.2.0-3` idle is again `2.5-3%` (any hpet=off do not work now)

So i went again back to `pve-qemu-kvm=9.0.2-5` and it's stable `0.6-1.2%`.

After every upgrade/downgrade or set hpet i rebooted the VM in proxmox.

Decreased in my case

i rebooted the VM.

I believe you have to fully shutdown the VM, & then start again.

Shutdown the vm
Start the vm
On one node was forced to reboot the host for another issue

Known issues:
Pass-through of integrated graphic card (iGPU) in legacy mode seems to be broken on i440fx (ref this thread).

That note should be added to the changelog for 8.4 under Known Issues & Breaking Changes. One of my systems requires the pass-through of an Intel iGPU and broke with the update to 8.4.
