The VM rows of the instance lists used instance.proxy.instance.info in
every state check, the vCPU column and the action buttons. A template
calls the method on each lookup, so every row made 7 virDomainGetInfo
RPCs (8 on a compute's instances page), and the memory column read the
domain XML once more.
- Instance.info reads virDomainGetInfo once per request; the lists and
instance_actions.html use it.
- The memory column of both index views comes from the same info
(current memory) instead of the domain XML. The value is the same:
checked against currentMemory for every running and shut-off VM of
the test hosts.
A row now makes one info call and one XML read (the title). The new
test counts the calls in the grouped and non-grouped index and on the
compute instances page; it fails on the previous code with 7 and 8
calls.
