Do you mean that you want to monitor the host system from the guest? Can yo= u not
just SSH into the host from the guest?=C2=A0 You can also infer CPU=C2=A0 u= sage=C2=A0 from=C2=A0 the
/proc/stat file on the host system, if you can share=C2=A0 files=C2=A0 over= =C2=A0 NFS=C2=A0 or=C2=A0 some
other file-sharing means.

I have ssh ac= cess (including root) to the guest but no access to the host.
