Hi, Too lazy to explain again so I'll just c&p conversation I had about the issue with Eric on IRC:
<zeenix> is timeouts on session libvirt (or in general) something new? <zeenix> libvirtd startup seems to now take a few seconds so Boxes UI is all empty for that amount of time <eblake> it's been around for a while; qemu.conf has settings to control how long it should take <zeenix> unless Boxes is launched before libvirtd timesout <eblake> but there is a relatively new patch that makes the libvirtd -t actually be useful for qemu:///session <zeenix> don't think i ever changed that, at least not recently <zeenix> that could be it <zeenix> i only saw it happening after i update libvirtd (after a month) <eblake> if you're seeing some delays in starting libvirtd, those are probably worth fixing <zeenix> s/update/recently updated/ <zeenix> yeah <zeenix> i'll try to write a test app <zeenix> no need, i can reproduce with virsh :)

You can try turning debug logs on and hopefully it will let more light in. To turn them on:
$ cat ~/.config/libvirt/libvirtd.conf log_level=1 log_outputs="1:file:/tmp/libvirtd.log"
Moreover, if you could upload them somewhere then so we all can take a look.
Here you go :)
Yeah, Daniel was right; It's because we are querying capabilities:
You have too much qemus there :) Libvirt spent ~7 seconds there.
Yeah, capabilities query has always been slow on my machine at least. I think I've even a bug against libvirt for that. I'll see qemu packages allow me to remove the qemus i don't need as workaround in the meantime.. Should i file a bug about this btw or whining on list is enough? :) -- Regards, Zeeshan Ali (Khattak) FSF member#5124
