    Hello,

    I'm running PVE 4 and PVE 5. I noticed 'Windows server 2012 R2' VM on PVE 5 are slower to start than on PVE 4. Anyone experiencing this problem?

    I'm using templates VM migrated from PVE 4 to PVE 5. It's fast to boot on PVE 4 but really slow to boot on PVE 5.

    Now I suspect default memory ballooning checkbox that was introduced in v4.4 that may the cause of this issue.

    i cannot imagine how, since the default settings stayed the same (only an additional settings got exposed)

    but there was another thread with similar symptoms, afair the solution was to install the ballooning service and driver

    Hi Dominik,

    Would unchecking ballooning in v5 the same as pre-v4.4 "use fixed sized memory" option?

    I think I may have resolved the slow boot up issue by 'unchecking' the default balloon option in memory setting.
    It seemed the boot up is much faster without ballooning.

    hi, no the default (checked balloon and min memory equals max memory) is the same as in v4, we simply changed how we presented it

    great that you found a solution, but did you also try to install the balloon service as well as the driver like i mentioned?

    Yes, I've installed balloon service and memory usage is very much lower and accurately reported on host that matches memory usage on Windows OS performance monitor. VM startup is also much faster due to more memory available to the host now.
