High memory usage by kvm process

[special_case]

My proxmox has little free RAM available, so I ran top to see where it was all going. And it turned out that one of the kvm is using 25% of memory. Any suggestions for why this is happening? I could always do a kill -1 from the command line, but I'd like to understand why this happened and what I might do to prevent it.

The kvm processes are running your VMs. You probably have a VM that you gave that much memory (and maybe you are using PCI(e) passthrough?). Kill it and see which VM stops running if it is not clear from the 4 or 5GB of memory which VM that is.

Not sure if it is possible with top, but with htop (apt install htop) you should see to which VM that KVM-task belongs to.

Thanks @leesteken. I was incorrectly thinking the kvm process was the proxmox GUI console. It being the an VM makes a lot more sense and isn't that worrying.
