Hi,<br>
<br>
Sounds like libvirt/qemu have a problem restarting the VM. Are the
config files for those daemons under /etc/libvirt set up identically
on all your hosts? Did you make sure that the user that starts the
kvm process is able to read en write to the files? (In my install I
added the user "qemu" to the "oneadmin" group to make that work.)<br>
<br>
You should have a log file for this particular VM in
/var/log/libvirt/qemu/one-[vm-id].log. What does it say?<br>
<br>
You say it happens occasionally, so not always? Does it always fail
when you migrate tot this particular host, or also occasionally? If
occasionally, you have to look for things that change from time to
time. Do you have config files maintained by chef/puppet/cfengine?
Do you have user accounts maintained by ldap/nis? If this host
always fails, it must be bad config of this host; compare it to the
other hosts that do work.<br>
<br>
Where does the "unable to read from monitor" come from. Is it
opennebula? That is kind of normal: it tries to read the status for
the VM but since it is not up, it fails. But actually, that should
not give you a "connection reset"... <br>
<br>
<br>
What you can do to test your setup when it fails:<br>
<br>
Go to the directory with the files and before you change anything,
so a "virsh create deployment.X" where X is the highest number you
can find in that dir. )In your example, it would be 2). (You will
need to be root for this or you will not be able to use the "system"
libvirt space.)<br>
<br>
If that "just works" then you have a real strange problem. If it
gives you errors, try to solve them. :)<br>
(If you do not know "virsh", you should read up a bit on it.)<br>
<br>
Hope this is a bit helpful.<br>
<br>
