How to improve integration in OVH environment

[bago]

Hi all,

i know you don't support OVH version of proxmox, but I think some of I ask can be used in every regional cluster (when your master and node are not on the same switch/lan).

You probably know OVH has a way to route the IP "failover" from one server to another and you can either do this manually from their manager or programmatically via SOAP API.

I succesfully tested live migration between 2 proxmox 1.5 KVM hosts. Sometimes the DRBD cluster seems to break just after the migration, and I don't understand why, but this is for another topic.

Live migration takes few seconds and when I run live migration I also run a script to update the IP routing on OVH and wait some minute to become rerouted.

Now, I'd like to improve on this:
1) Is there some "hook point" I can hack in order to automatically call my ip failover rerouting script whenever the VM is moved (live or not live) ?
2) I thought about adding a temporary IP/ethernet tunnel between nodes while I wait the IP to be rerouted for real: again, do you have any suggestion on the better place to start integrating this things?

Thank you for the great product!

you should take a look here, quite new on OVH
http://www.ovh.co.uk/items/virtual_rack.xml

interesting for you?

Unfortunately Virtual Rack is not applicable to my configuration, so I'm still on the "software" solution.

Any hint about what code should I "hook" to?

FYI, the whole cluster communication is subject to change in 2.x. Feel free to take a look the source code but we will not invest too much time to change the current setup.
