Dear Simone,
it should be 60 min , but I have checked several hours after that and it didn't update it.
[root@engine ~]# engine-config -g OvfUpdateIntervalInMinutes
OvfUpdateIntervalInMinutes: 60 version: general
How can i make a backup of the VM config , as you have noticed the local copy in /var/run/ovirt-hosted-engine-ha/vm.conf won't work ?
I will keep the HostedEngine's xml - so I can redefine if needed.
Best Regards,
Strahil Nikolov
