Randomly start VM on boot

[obrador]

Hi, I configured a 2-node cluster with proxmox 2.0. What happens is that on one node all of the kvm Virtual Machines some times doesn't start at boot (and they are marked to start at boot), it's quite random, but it seems that if the second node is off-line, none of the VM starts, but if the second node is on, all the VM starts corectly... I need to test more, but I'm annoyed about that. Any ideas? is this normal?

Yes, because you need quorum do start VMs

But it doesn't happen with the other server.

To better explain I'll name both servers as A and B. I tested to reboot both servers at same time and one of them (B) started all VM and the other (A) none of them (surely because node B was not started). It's always the same server (A) that is unable to auto start VM at boot. If the node B is already running, server A is able to auto start all of their VM.

Is there any conf to set the number of required nodes for quorum?

Many thanks in advance.
