Description Jürn Brodersen

2019-03-07 15:33:43 CET

Port to 4.4

+++ This bug was initially created as a clone of Bug #48098 +++

UVMM should detect CPU/RAM/... over-commitment when a live migration is triggered and issue a warning.
A customer has regular problems with over-commitment because they have quite a lot of KVM servers and always checking resources of both migration partners quickly becomes a tedious task.
