Re: HA-enabled SSVM and CPVM?

[Ahmad Emneina <ae...@gmail.com>]

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...

Ahmad

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.

Brian,

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