Subject RE: HA-enabled SSVM and CPVM?

You are correct, whilst the SSVM and CPVM System Offerings are not flagged as HA, they are
treated as such, and if either should fail they will be automatically restarted on another
Host, in addition, if you destroy them, they are also automatically re-generated from the
System VM Template.


There is no need to create new SSVM / CPVM System Offering flagged as HA, in fact doing so
may cause so unexpected behaviour.

CloudStack treats the system vm's as highly available but monitors and recreates the vm's
in a different way. Say a few failed starts of a ssvm, would get cloudstack to destroy and
recreate the vm on another host. Thats my observation at least...
