Subject Re: unable to connect to /var/lib/libvirt/qemu/v-1-VM.agent
Date Mon, 21 Apr 2014 05:47:27 GMT
Sorry, actually I see the 'connection refused' is just your own test
after the fact. By that time the vm may be shut down, so connection
refused would make sense.

What happens if you do this:

'virsh dumpxml v-1-VM > /tmp/v-1-VM.xml' while it is running
stop the cloudstack agent
'virsh destroy v-1-VM'
'virsh create /tmp/v-1-VM.xml'
Then try connecting to that VM via VNC to watch it boot up, or running
that command manually, repeatedly? Does it time out?

In the end this may not mean much, because in CentOS 6.x that command
is retried over and over while the system vm is coming up anyway (in
other words, some failures are expected). It could be related, but it
could also be that the system vm is failing to come up for any other
reason, and this is just the thing you noticed.
