It may not necessarily be unreal. Do you use memory ballooning? Bug tickets must have version flags set prior to targeting them to a release. Please ask maintainer to set the correct version flags and only then set the target milestone. Ballooning? Altogether yes. we would need at least one example where it doesn't correspond to what you see in the guest. High overcommit and a lot of dynamic changes going on these might be the reason...and those would be correct values try to reproduce without a balloon device in VM (then the guest "sees" the same amount of available RAM all the time, there is no backpressure when host runs out of RAM) Moving from 4.0 alpha to 4.0 beta since 4.0 alpha has been already released and bug is not ON_QA.

Thanks. Actual vesion oVirt Engine Version: 3.6.5.3 looks OK. Thank you Karel for the feedback! Closing as fixed in current release. |
