Getting 'real' guest uptime

[Sam T]

Howdy!

Just a random one. From the host system, is it possible to query a guest's uptime using the qemu guest agent? Specifically, this is for querying a guest's uptime accounting for live migrations - e.g when I live migrate a machine with a day of uptime, proxmox will now start counting uptime from 0 on the new host. Thanks in advance!

You can run qm guest exec for any VM(ID) to run any command inside the VM (from the Proxmox node that runs the VM). It's probable also possible to run this via the Proxmox API remotely.

Oh cool, thanks! That's exactly the kinda badger I was after there

Appreciated! It definitely seems a lot more relevent to show a guest's uptime from *its* pov, but I can also see how that could be a nightmare to set up
