Running commands on quest with qm guest exec errors

[Kobus]

Hi
I have proxmox 5.4-13 installed.
I have enabled the qemu agent.
When I try to run a command omn the remote host I get:
qm guest exec 60037 ls
Agent error: The command guest-exec has not been found
Do I need to install or enable anything else please?

Do I need to install or enable anything else please?

Have you installed the guest agent inside of your VM? (you have not written it, therefore I ask)

I have proxmox 5.4-13 installed.

Why haven't you updated to PVE 6 already?

Hi
Sorry, I should have said that I have installed it. We run mostly CentOS 6 and 7 VM's and soon to add some 8.

hi,

unfortunately the capabilities of qemu-guest-agent aren't always the same between different distributions, since the versions or implementations don't always match.

"version" : "0.12.1"

it seems like this particular one is pretty old, so maybe that's why it doesn't have guest-exec.

what is your vm distribution?

Hi
Yes it is. The agent that is installed on CentOS7 is 2.8.1 and that does allow me to do stuff. I might try to get a later version installed, but we pretty much stay clear of source installations. So I will need to hunt for a verion and maybe even create a custom rpm for pour CentOS servers.
Thank you for your time.

Just get the src.rpm of a new version and build it with rpmbuild. I do that all the time and it almost as smooth as using Debian packages :-D
