[PVE-User] HA behavior with VMs (PVE 2.2 pre-release)

Hi,

If you enable HA for a VM or CT, make sure that the VM/CT is off. As soon as you enable HA, the resource manager (rgmanager) takes control and starts the VM/CT. you can still live migrate manually. If you click “Stop” the VM/CT will be stopped and not started again by rgmanager.

If you need to reboot  a host, live migrate all VM/CT´s to other node or stop the VM/CT.

If your system does not work like this, it’s a bug or configuration issues. (stopping rgmanager is not a suitable testcase to simulate a failed node)

Best Regards,

Martin Maurer

If you mean disabling HA allows me to regain full control of the VM, I do understand that, and at the moment consider it a workaround.

Or do you mean by design, HA enabled = VM unconditionally runs and can't be powered off, regardless of the autostart parameter setting?
That seems unlikely to me, isn't mentioned in the wiki HA section, and is why I emailed.   If that's not how you intend it to work, I'd be happy to open a bug.

Simply remove the VM from HA if you do not want that behavior.

Note: HA = High Availability

Because of #3, it seems I can't have a powered-off VM sitting there, that will be moved to another host in the event whichever host it's on goes down.   Seems like a bug to me.  Maybe the behavior of #3 and 4 are related.   I want to make all my VMs "protected" by HA whether they're running or not, so they always remain accessible regardless of their powered off/on status.  Also, why can't I have an HA-protected VM stay powered off?  :-)
