If you want a virt-manager like display of VMs, 'virt-top' is the tool to use http://et.redhat.com/~rjones/virt-top/ Regards, Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.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@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list

Since it comes from epel one could install it though. I gather extended info in virsh list is not wanted upstream then? I would find it handy when being in virsh to issue a "list" and find the commited memory, cpus of running VMs before firing up an additional VM. This is a little help to prevent overcommiting on a host and no-one could say he wasn't warned.

Seems like the loop in virCgroupAddTask() should just keep track of which hierarchies it has already written to. Just a small temporary hash table or for that matter a small array that you walk linearly... -serge -- Libvir-list mailing list Libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
