When the XCPNG host restart, it restarts running directly, instead of being in maintenance mode
-
@Pilow @olivierlambert I have the same issue with suspended VMs restarting without my request. It happens during some host upgrades/reboots or NFS storage reconnects.
-
@olivierlambert XCP-ng will include an option to keep hosts disabled after reboot. This will be part of the next update for xapi. (25.33.1) This was contributed upstream by Andriy and is used by adding an extra parameter to disable:
xe host-disable uuid=$HOST auto-enable=false. -
Ah nice!
-
Hi,
@olivierlambert, @psafont @pilow Perfect, thank you a lot !!
-
@psafont do you know if it's already available since then in XCP-ng 8.3? If yes, worth checking XO team to also making this option visible in the UI

Yes, we're shipping xapi 26.1.3, which includes this enhancement.

Thanks! I will make sure the Maintenance mode button in XO extends with this new parameter.

@olivierlambert having done a RPU yesterday on 3 hosts, I still have the "bug" where some VMs with "auto start" switched ON, but halted on purpose, reboot when a host is rebooted.
we do stop some VMs during RPU to lessen the migrate times, but at every host reboot, they DO START UP
annoying. not critical, but annoying.

@Pilow Are these VMs HA-protected? If yes, maybe when HA is re-enabled after the RPU it believes that the VM is down and must be started.
There's a pool-wide setting tell HA not to restart a VM that was manually stopped:
xe pool-param-set uuid=<your pool uuid> ha-reboot-vm-on-internal-shutdown=false -
@stormi no, we do not use HA, it's disabled on the POOL and on the VMs
-
I did verify and yes
ha-reboot-vm-on-internal-shutdown ( RW): trueit is enabled on our Pool. but no HA
ha-enabled ( RO): false
