Migration and priority

[Sarlis Dimitris]

I would like to get some extra info regarding the migration on HA system with 3 nodes.
My question will start with a sample of setup,

I have node1 with 3 VMs (100, 101, 102)
Node2 with (103 & 104)
& node3 which is not identical with node1 & node2 but yet a simple PC just to traffic the HA.

So lets say that node2 get's damage and I have 103 VM in HA. Can i set the priority, to guide it migrate to node1?

I made a demo fail and the VMs gone to node3.

Is the priority fixed?

Also, should I go with dedicated cluster network address to all 3 for faster results in migration and failover?
If yes, can i do so with virtual network adapters?
All 3 nodes have 2 lans physically..

Thanks for reading me

you can use a 'restricted' HA group for this, where only node 1 and 2 are members. a separate cluster network is recommended for stability reasons, especially when using HA (loss of connectivity means fenced nodes!). it does not make failover go any faster.
