HA vm restart


VMware, HA, Virtual Machines, VMware ESX, ESX Server, VMware HA

Hi blog!!

I have ESX 3 server with HA (high availability).

If the server ESX crashes my vm's are moved to another ESX server, when all my vm's moved to the new ESX server do they keep their status (power on) or their status change for example they restart. Thanks

The machines which are moved over to the new host will need to be restarted as the memory which they were using is no longer available as their old host is offline.

the actual behaviour of Vmware HA is the following:
whan a physical machine dies all the VMs that are registered on it are not moved but restarted on the others physical machine that are part of HA cluster.
one of the biggest mistake that a lot of people do is to think that vMotion is implied in A mechanism: HA do not relies on vMotion and most important do not relies on Virtual Center.
If you have and HA cluster go on a physical machine via putty and issue an ‘ 

esxupdate -l query

‘ command: at the end of the list of patches you’ll see the list of agent running on the host: two are for HA.
