Trying to turn off HPET for VM

[smirk]

Hi

I am running OpenVMS in a KVM machine on proxmox (well I was), granted it's not a supported option but I can do it ;-). To get OpenVMS running inside Proxmox you need to turn off HPET otherwise it simply hangs during boot up.


The workaround, had been to add the line:
args: -no-hpet

into the appropriate virtual machine's CFG file. Since a relatively recent update to proxmox, sadly I cannot remember when exactly but I'm currently on 8.2.4, this workaround fails and all I now get when trying to start the virtual machine is the error:

kvm: -no-hpet: invalid option
start failed: QEMU exited with code 1

My google-fu has completed failed me and I cannot find what the alternatively arguments/options for KVM would now be,

I appreciate there will not be many people running OpenVMS but I'm hoping someone else needs to turn off HPET in virtual machines and knows the solution with the latest 8.2 series of Proxmox

Thank you, Fiona, for the quick reply. That did the trick.

Just for ease of future searching (the diff file in the bug report was not the clearest to me ;-) . ....

The solution to turning off hpet was to replace the line:

args: -no-hpet

with:

args: -machine hpet=off

In the virtual machine's CONF file (in /etc/pve/qemu-server)
