When I was using libvirt directly, I did see that, but could never make it work. This is some of the additional memory/performance information we would be interested in. In the event I stick with using virsh, it is available it as well as I have yet to see it?? -----Original Message----- From: Daniel P.

It depends what libvirt APi you are referring to when you talk about memory utilization. virDomainGetInfo returns data about the memory allocated to the guest by the hypervisor. This says nothing about what the guest OS is doing with the memory. eg, the guest has been given 500 MB, but its OS may have only used 200 MB so far. We have a fairly new API virDomainGetMemoryStats that can give info about how much of its allocated memory a guest has actually used, along with stats on swap in/out and major/minor fails. This is only implemented for KVM + virtio though and requires a guest with a pretty new balloon driver to report the data Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://deltacloud.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :| -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
