XCP-ng 8.3 updates announcements and testing
-
@Pilow I've been wondering lately if I should do a Rolling Pool Reboot before any Rolling Pool Update. This might allow me to identify problems in advance and I would also be installing the patches on freshly-rebooted hosts.

@robertblissitt yup, afterward this seems to be a good best practice...
my hosts were up for 4 month, and because of DNS resolution problem had 77 patches to catch up (80 for one with advanced telemetry enabled)a rolling reboot would have probably put in front the initial migration/evacuation problem (and subsequent zombies VMs)
and no patches applied, and no pool in a semi upgraded state
note to my future self, try a rolling reboot first.
