[PVE-User] qm cli

[Alejandro Bonilla]

Hello,

Whenever I run commands from within one of the nodes, they appear to be targeted to the local system only.

root@r620-1:~# for i in {123..128}; do qm snapshot $i ready ; done
2020-11-10 09:15:21.882 7f81d2ffd700 -1 set_mon_vals failed to set cluster_network = 10.0.0.0/24: Configuration option 'cluster_network' may not be modified at runtime
...
Configuration file 'nodes/r620-1/qemu-server/124.conf' does not exist
Configuration file 'nodes/r620-1/qemu-server/125.conf' does not exist
…
...
Configuration file 'nodes/r620-1/qemu-server/127.conf' does not exist
Configuration file 'nodes/r620-1/qemu-server/128.conf' does not exist

Is there a way to “centrally” run commands?

Thanks

Yes, this is how it works.

I for one would really love to use qm on a cluster base, instead of
nodes. I currently first need to find out which node a VM runs on, then
log on to that node, and then run the qm commands.

Is it usefull to create a feature-request for this in Bugzilla?

For qm, yes. For pvesh, no.

Instead of the initially mentioned command
> for i in {123..128}; do qm snapshot $i ready ; done

just do something like
> for i in 100 101; do pvesh create nodes/dev/qemu/$i/snapshot --snapname ready; done
where you replace dev with a node name of your choice. This API path is documented in [0].

qm snapshot is actually one of those commands that is mapped pretty directly to the API [1].
