<p dir="ltr">Hi Andreas,<br>
I know the migration only transfers RAM from one node to the other.<br>
But this still takes over a minute at 100Mbps.<br>
My setup's purpose is research, redundancy is not the goal here.<br>
I'm running the NFS storage and the management on one of the nodes, if it's relevant.</p>

Hi Yuval<br>
<br>
i think migrate was only the RAM not die virtual hard disk.<br>
For so an scenario you need one separate Ovirt Engine (Management) one separate Storage and two Ovirt Nodes.<br>
An then you can build a HA Solution to reduce a Node failure. the single point of failure there will still give<br>
Eg. Storage, Ovirt Engine and Network. But i think you can cluster the application and storage from the nodes. Using drbd, ucarp, etc.<br>

Betreff: [Users] Choosing which network to run VM migration on ovirt 3.1<br>
<br>
<br>
Hi,<br>
I'm running the following setup:<br>
2 hosts,<br>
each has 2 physical NICs,<br>
the first NIC (which is bridged to ovirtmgmt) is a 100Mbps ethernet card connected to a switch (and to the internet)<br>
the 2nd NIC is a fast Infiniband card which is connected back-to-back to the other host.<br>
<br>
<br>
both links are running fine, and I managed to have the 2nd host mount the storage via the fast link.<br>
The problem is that VM migration takes place over the slow link.<br>
<br>
<br>
How do I configure the cluster so that the migration uses the fast link?<br>
I've already created a network using the web interface. the migration still uses the slow link.<br>
<br>
<br>
<br>
<br>
Thanks,<br>
<br>
<br>
Yuval<br>
