agent/exec with pvesh in PVE8

[ara-stgu]

I am running a script on a PVE cluster that executes commands in various VMs on different nodes. The script is making use the pvesh command and the API-Endpoint https://pve.proxmox.com/pve-docs/api-viewer/#/nodes/{node}/qemu/{vmid}/agent/exec.
Since the upgrade to PVE 8, pvesh fails to execute commands in VMs that are are running on nodes different from that node were pvesh is executed, as shown below:

root@node1:~# pvesh create /nodes/node1/qemu/1001/agent/exec --command 'whoami'
┌─────┬───────┐
│ key │ value │
╞═════╪═══════╡
│ pid │ 6224  │
└─────┴───────┘
root@node1:~# pvesh create /nodes/node2/qemu/1000/agent/exec --command 'whoami'
proxy handler failed: Agent error: Guest agent command failed, error was 'Failed to execute child process (No such file or directory)'

I assume this occurs because of the change in this specific API endpoint with the upgrade to PVE 8. Am I using the command incorrectly or is this a bug in the pvesh utility?

Hi,
thank you for the report! I can reproduce the issue here and will investigate further.

EDIT: sent an initial patch for discussion: https://lists.proxmox.com/pipermail/pve-devel/2023-November/060465.html

Should be fixed in pve-manager >= 8.0.8: https://git.proxmox.com/?p=pve-manager.git;a=commit;h=96aee647a8d216e0e0a43597ba820cc5490f200c
