[Pacemaker] setup of a cluster - principal questions

i'd like to establish a HA Cluster with two nodes. I will use SLES 11 SP2 + HAE.
I have a shared storage, it's a FC SAN. My services will run in vm's, one vm for one service. The vm's will run using KVM.
First i thought to install the VM's in plain partitions, without any filesystem. I read that this will be faster.
But i tried installing two vm's, each one in a raw file, and this is fast enough for me.
On the shared storage i will create OCFS as filesystem.

Now my questions:
- is live migration possible with this setup ?
- is it possible to run some vm's one node 1 and some others on node 2 ? As a kind of load balancing ?
- what do you think about my setup ?

Thanks for amy answer.
