so I dont think there is a network or disk bottle neck now. in watching instances launch I see that the disk image itself gets copied out to the compute node in < 1 minute, the xml file for libvirt gets created. then a pause of ~ 20 minutes then the kvm process starts up and off the VM goes just fine. aside from messages like: 2013-05-01 19:43:40.363+0000: 2377: warning : virAuditSend:135 : Failed to send audit message virt=kvm vm="instance-0000014c" uuid=d72afa21-844a-4ea0-8b96-0a4e5e4da5eb vm-ctx=? img-ctx=? model=stack: Operation not permitted
and these dont start until the kvm process starts, I see nothing in the logs. but then I dont have debug on which I will do next. what is causing the pause in between is the question. hopefully debug on will help. s On 05/01/2013 11:43 AM, Rick Jones wrote: > On 05/01/2013 10:43 AM, Steve Heistand wrote: >> there may be some network issues going on here, trying to shove some amount >> of data >> bigger then a few Gig seems to start slowing things down. > > If you think there is an actual network problem, you could I suppose try > exploring that with netperf or iperf.
