Hi,
We are using Ubuntu 10.04 eucalyptus 1.6.2 and libvirt 0.7.5. We found
eucalyptus-nc sometimes hangs in virDomainCreateXML, and never gets
response from libvirtd.
After 2 days of investigation, I found there is another libvirt client
connects to libvirtd 'qemu:///system', which is the same URI as
eucalyptus-nc. The bug never shows after I disabled the client.
My question is:
1, can I have multiple clients connect to qemu:///system?
Yes, since 0.6.0 we support concurrent connections, however, there
have been releases where this is buggy. Also one thread may still
block another thread if it holds a lock for a long time.
2, is this an bug in libvirt and has it been fixed?
I can't remember an specific bug in that libvirt release, but it
is quite old now. You might consider trying a newer libvirt.
