We’re using Proxmox that has support for HA, they do it per-vm.
We’re doing it manually right now though, because we like it :).
When I looked at it I couldn’t see a way of just allowing a set of hosts
in the HA (i.e. not the storage nodes), but that’s probably easy to
solve.
Ah, Proxmox. I test drove this about a year ago and while it has some nicefeatures the "black box" approach of taking over bare metal hardware andthe ancient kernel doesn't mesh with other needs I have here.
The ancient kernel is not needed if you’re running just KVM. They are working on a 3.10 kernel if I’m correct though. As it’s Debian 7 in the bottom now, just put in a back ported kernel and you’re good to go. 3.14 was bad but 3.15 should be ok. And it has Ceph support now a days :)
Cheers, Josef
Thanks for reminding me, though.
No problemo :) ChristianCheers,
Josef

Hello,
What are people here using to provide HA KVMs (and with that I mean
automatic, fast VM failover in case of host node failure) in with RBD
images?
Openstack and ganeti have decent Ceph/RBD support, but no HA (plans
aplenty though).
I have plenty of experience with Pacemaker (DRBD backed) but there is
only an unofficial RBD resource agent for it, which also only supports
kernel based RBD.
And while Pacemaker works great, it scales like leaden porcupines,
things degrade rapidly after 20 or so instances.
So what are other people here using to keep their KVM based VMs up and
running all the time?
Regards,
Christian
