Hello
I thought it would be cool if virsh list behaves a bit more like
virt-manager or xm list because as a system-administrator i want to know
with one look what VMs are active, how much memory they commit and what
their runtime is.
I implemented this with the following patch which give such an sample
output.
What is your opinion and/or have i missed something?
[root@rr016 ~]# virsh list --all
