The command dommemstat can give you memory stats for a specific domain and with domstats you can get plenty of stats for all domains or just the specified. You can pass the parameter --cpu-total to see the total in the moment.

First get a virsh interactive console by typing virsh on your command line and then, once inside virsh's console, issue the following command:

virsh # domstats --cpu-total

The previous command will give you the CPU stats for all domains. If you have virt-manager you can see live some graphs and other nice stats, and if you want to collect them for a time you would need some other tool, I would recommend collectd and its 'virt' plugin

  dont forget to always check the shell/program from which the command has been run... meaning that the command as per the answer was run from within virsh interactive interface. From bash, you would need to call virsh domstats --cpu-total <domain> for specific domain or the simpler, without any specifics
