From: Tianyu Lan <Tianyu.Lan@xxxxxxxxxxxxx> Sent: Monday, January 20, 2020 7:49 PMCurrent code has assumption that balloon request memory size aligns with 2MB. But actually Hyper-V doesn't guarantee such alignment. When balloon driver receives non-aligned balloon request, it produces warning and balloon up more memory than requested in order to keep 2MB alignment. Remove the warning and balloon up memory according to actual requested memory size.
