Hi everyone!

For my LXC instances I get the free disk space in the Summary.

How do I get the same for my Ubunbu VM where I do not see the usage of the bootdisk? :)

QEMU Agent is installed an running (I do get the IP adresses in the Summary)

Thanks!
 
You cannot. This information is heavily guest OS dependend and there is not one way to do it for every possible guest os. Therefore it is not implemented. Please use proper monitoring software to do what you want.

Thank you for the info, I though the QEMU Agent would be able to provide this info. :)

It can, but this depends on the guest and that's why there is no general availability.

It's also not defined what a boot device is. In a default UEFI Linux install, you will have at least UEFI, /boot and / ... so 3 mountpoints (could be partition, disk, volume ... you name it). Which one should be displayed? For a container, there is no need for UEFI or /boot, because the kernel from the host is used and therefore it is just one mountpoint that is needed.
