XCP-ng 8.3 updates announcements and testing
-
XO isn't subtle and will ask for reboot regardless of the type of update (because for now there's no way to know if reboot is required)
-
@olivierlambert lol okay got it

-
I got the results. You can access our lab, feel free, nothing is productive. Support ID: 40797
High count of VDI / VMs on single SR make entire Storage slow.

Migration fails because of:

@olivierlambert Seeing some failure/errors on CR jobs. It leaves VDIs attached to Control Domain... Next run it normally works. I have not seen this error until after the current sm update. Running XO (commit 7e144).

Hello @igorglock, Damien is in holiday this week but he identified the issue and a patch should be tested for the next release of SM.

@stormi I'm also getting error on some VMs while trying to export a disk and also trying to even start some VMs from NFS (that were fine before).
