[SOLVED] qemu-ga - it's possible to reboot via pve from VM?

[czechsys]

For example, when i change VM name, without reboot on PVE side it's still using old name in qm process on PVE. Or use some swap on PVE.

Can i use qemu-ga to send reboot (itself) command from VM to PVE and if yes, what's correct syntax?

Hi,

no, it is not directly possible to send a command from the VM to the PVE via the qemu-ga.

But you could use SSH on the VM to trigger a custom script on the PVE which shuts the VM down and boots it again.

Thanks for reply. Exposing PVE infra to all VMs is no go for me. It will be nice feature for qemu-agent to "reset" process on PVE.

Using the PVE API should work too. You could create a user that is only allowed to start/stop/reset VMs (only give the "VM.PowerMgmt" privilege). And you could give that user a token to authentificate with the API. So in worst case a VM might shutdown another VM and you revoke the token.
