Hello Olivier,<div><br></div><div>Very good question!</div><div><br></div><div>You could do two things:</div><div>1) Write a hook [1] on the event of running vm to do "virsh autostart one-<VM_ID>" [2]</div>
<div>2) Add a line in the deployment script [3] to execute "virsh autostart one-<VM_ID>" ( after line 29 of the script for example)</div><div><br></div><div>[1] <a href="http://libvirt.org/sources/virshcmdref/html/sect-autostart.html">http://libvirt.org/sources/virshcmdref/html/sect-autostart.html</a></div>

<br>
I'd like to make sure that (kvm) VMs running on hosts get restarted whenever<br>
hosts are rebooted.<br>
<br>
Is there such a setting somewhere ?<br>
<br>
If I understand correctly, VMs with "persistent" images (on a shared<br>
file system) won't suffer too much of a host restart in principle : the<br>
disk image is kept intact, normally (although I'm not sure how too fast<br>
the shutting down of kvm VMs is performed for running services inside<br>
the VMs : no proper close of files, cache dumps, etc.)<br>
<br>
But when the host is restarted, the VMs stay in unknown state and I have<br>
to restart them manually.<br>
<br>
Would there be a chance this can be done automatically, or better, they<br>
are suspended upon shutdown of the host and resumed when it restarts ?<br>
<br>
Sorry if this is a FAQ, but I couldn't spot the response, and I plee<br>
guilty in advance of not having all read the (very prolific and) very<br>
good documentation.<br>
<br>
Many thanks in advance.<br>
<br>
P.S. I'm running 3.2.1 from Debian wheezy<br>
