Which VM should be started firstly in the two VM with same priority

In the HA cluster, if the two virtual machines is set to high.

When the host is crashed, which one is booted firstly?

Good question.

Multiple VM's should be able to start simultaneously following a failure.

Although if you had 10 virtual machines all set to high priority then I think it's alphabetical.

That's how the host failure works with HA. A host fails and everything moves to the first available server in the cluster in alphabetical order.

"Although if you had 10 virtual machines all set to high priority then I think it's alphabetical. "

I second that thought. Alphabetical seems to be the fall back in VI.

I think this is what you were referring to...

Order of VM restart:

Restart only powered on VMs that are HA-enabled.VMs with higher priority will get started first.

Which Host?

Host Failover Sequence Algorithm of HA

•In VC2 , goes alphabetically through host list, picks the first host that has enough capacity to accommodate a VM.

•In VC2.1, picks the host with the most unreserved capacity.
