Tomas Jelinek has submitted this change and it was merged. Change subject: core: Memory hot plug always starts with min. block ...................................................................... core: Memory hot plug always starts with min. block See javadoc of UpdateVmCommand#hotSetMemory for reason. Size of minimal block on x86 is 128MB so validation of size of hot plugged memory was reworked: HotSetAmountOfMemoryCommand checks architecture constraints: x86 ~ 128MB, ppc ~ 256MB, UpdateVmCommand checks against HotPlugMemoryMultiplicationSizeMb config value. This patch intentionally avoids deeper refactoring since it's intended to be backported.
