Hi.

Yes I did mean deleting volumes from storage pools.

Just to confirm when I remove the volume - the virt-manger (GUI) crashes -
however it does actually delete the volume  (its more of an annoyance)

When it crashes (it crashes on KDE4 and gnome3) it brings down my KDE4
desktop also...

The actually KVM/libvirt server doesn't crash though (thankfully..)

Shall I submit a bug report for the virtual-machine manager?


Regards
