Include checking for root volume status when checking vm's

[JVC-MSF]

When checking a container with the mode equal to "vm", please include also checking the used space in the root volume.

Having free space in the root volume is condition to be able to consider that the container is properly running.

Right now there's no event when the root volume becomes full.

Root volume = rootfs of the container?

[JVC-MSF]

Yes.

Sorry for the delay, I missed the notification.

I need to check if this can be done with the pve api
