xm process running with high cpu

[Noegdip]

We see the process xm running on our server with very high cpu usage and it is causing problems. We have looked it up and think it is this

> The xm program is the main interface for managing Xen guest domains. The program can be used to create, pause, and shutdown domains. It can also be used to list current domains, enable or pin VCPUs, and attach or detach virtual block devices.

When we kill the process another one appears immediately. We were able to rename the application which stops it running but if we rename it back it gets executed and the cpu usage is at 100% again.

Our suspicion, which could be wrong is that it is being regenerated by cpanel. Possibly there is some cronjob ,that does not contain xm in the name, but when it runs if the file does not exist , it downloads it and then it executes it. When we stop it we see the pigz process running which is the backups so is it some part of that?

We're really stuck here so wonder if anyone can help with a possible explanation and hopefully a solution.

Hello,

I don't believe cPanel would spawn the process you mentioned, at least by default. For example, this process is not running on my cPanel servers. However, it is possible that a user created a cron that would spawn the process, or it could be operating system related. Although my experience with this process is limited, it appears to interact with the server's Hypervisor. If the process consumes abnormal amounts of CPU, there could be a problem with the server's Hypervisor. I'd recommend contacting your system administrator or hosting provider so they can investigate the process more closely and check for any potential hardware issues.
