CPU unit max limit changed in PVE 7

[SagnikS]

I upgraded one of my test nodes to try out PVE 7, and I noticed that one VM was not starting. The error was

TASK ERROR: start failed: org.freedesktop.DBus.Error.InvalidArgs: Value specified in CPUWeight is out of range

It seems that this is due to cgroups v2, where the max limit of this is 10000, unlike what was used before. I think this should be mentioned a bit more clearly and potentially as a breaking change.

Thank you for reporting this. We were able to reproduce this and are looking into how to handle it best. One of the next updates will contain a fix so that the VMs will still be able to start.
