@stormi
what about support for 8.2 and new CPUs like 7900/7950 ?

@olivierlambert
with HA enabled, if Windows VM will reboot from windows system scheduler - is this ok? Will this affect somehow on VM?

@olivierlambert
what about when system doesn't know that host if offline, but i know for sure that host is down, and i need manual control over starting/copying vm.
why then in those command exists --force, if it's not helping in anyway?

Try this in every VM's advanced tab in XO

@stormi
what about support for 8.2 and new CPUs like 7900/7950 ?

@Gheppy

I would have done those operation, if i wouldn't loose connection to xcp-ng.
I got only 1 IP address which is dedicated to pfsense, and from there i connect to xcp-ng (LAN side).

@dave-opc

Maybe it's possible to create a delay for autostart VM parameter, like 0 seconds start instantly, 60 seconds - to delay VM autostart.
I guess this will be useful for those who have slow HDDs and lots of VMs starting all at the same time.

@lukasz_s

If your Windows system restarts with no issues, you can try and go to Control Panel - File History - System Image Backup and create a copy of your system. Then create a new VM on 8.2 and Restore it there
