<pre class="moz-quote-pre" wrap="">Hello to all,
This is the first time I use HA on Linux. I'm still learning, and I
like?
it a lot.
I was interested to a active/passive system that can support virtual?
machines with live migration. For various reason I prefer VirtualBox
as?
the hypervisor.
I used an existing agent that I found here:?
<a class="moz-txt-link-freetext" href="https://forums.virtualbox.org/viewtopic.php?f=7&t=35372" moz-do-not-send="true">https://forums.virtualbox.org/viewtopic.php?f=7&t=35372</a>, improved it
and?
I would like to share it.
It is now more robust and ocf compliant and supports live migration
(aka?
teleportation in VBox's terminology). I'm testing it one week now on?
Debian Stretch and seems stable enough for production.
The assumptions in order to be used:
1) Both nodes should mount the same filesystem, the same time (ie
iscsi,?
cluster, nfs, and so on). I used glusterfs and works like a charm. I
put?
VM settings and images on it.
2) Both nodes should have reasonable similar hardware - close enough
so?
that teleportation can work - check VirtualBox's documentation
regarding?
teleportation for this.
3) Both VMs should have the same settings- if you put the settings
on?
the common filesystem as I did, then it is easy: create the VM on
one?
node, just add it on the other.
4) SSH keys should be exchanged between nodes. You see, migrate_to?
should be able to handle both nodes in order live migration?
(teleporting) to work.
5) Teleportation works by putting the receiving node listening on a
port?
- by default 6000. Ensure that the port is correct and accessible
from?
the other node.
Any comments are more than welcomed
Cheers
John (aka Ioannis)
