Hi,
There is a quite annoying thing, don`t sure if I can call it a bug.
How to reproduce:
- start a bunch of VMs, - stop libvirt, - start libvirt and immediately issue any call, say, 'virsh version', - delay until call completion may be fitted nearly as quadratic function from number of running VMs, qemu-kvm in my case (see link below). After this delay passed, any calls executed without slowdown, so problem is only a 'dead gap' after restarting service.
When the daemon is restarted it needs to reconnect to all the guests and that operation takes time. I'm not sure why it's not linear, but I think i experienced that a couple of years ago, so that doesn't sounds a recent regression. If you can look at what is going on, that would be useful Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
