<div>Hi,</div>
<div><br>
</div>
<div>Did you ever figured out how to “move” VM in case when VM host goes down? </div>
<div>I ran into the same issue last night. </div>
<div>RHEL6 cluster, same OS/KVM version. One of them VM hosts went down (error) and VMs running on that host were recreated on available hosts.</div>
<div>Recreated VMs lost work progress.</div>
<div><br>
</div>
<div>RHEL6 cluster is using shared NFS storage for system and “data” datastores.</div>
<div>Once host died, ONE attempts to connect to the dead host to access system datastore, which is already mounted on ONE controller under the same path (log below).</div>
<div>This is how system datastore configured:</div>
<div><br>
</div>
<div>TYPE: SYSTEM_DS</div>
<div>DISK_TYPE: file</div>
<div>TM_MAD: shared.</div>
<div><br>
</div>
<div>It’s mounted on all cluster nodes and ONED controller under the same path (/var/lib/one).</div>
<div>I’m probably missing something in system datastore configuration, which would tell ONED to access it locally, not via dead VM host…</div>
<div><br>
</div>
<div>Shouldn’t ONED start VMs on available host using existing config/disk files in system datastore?</div>
<div>And not delete/recreated it?</div>
<div><br>
</div>
<div>Thank you.</div>
<div><br>

<div dir="ltr">Hi,
<div><br>
</div>
<div>What do you exactly mean by "move"? If you are referring to migration, that's not possible, once a host goes down, the VM state is lost.</div>
