How can I provide more information? strace? virt-manager is notoriously a hog, because it polls tons of libvirt info. But if there was a noticeable change we might be doing something wrong, occasionally we regress somewhere and end up fetching domain XML on every tick period when we should be lazily updating it. Jens, are you still seeing this with latest F17 virt-manager? It's been bumped a few times since this was filed. Yes, I am afraid so - I noticed it again this morning... Trying now I see virt-manager is using about 8% and libvirtd 5.5% - no guests are running. Probably no regression - it has been happening for long anyway I believe. *** Bug 980393 has been marked as a duplicate of this bug. *** Upstream uses domain events now, and has been audited to cut down as much polling as possible. It can be reduced even further than the default by disabling CPU polling in edit->preferences. |
