[ovirt-users] Memory ballon question

Hello All, as a KVM user I know how usefull is the memory balloon and how you can both increase - and also decrease memory live (both Linux & Windows). I have noticed that I cannot decrease the memory in oVirt. Does anyone got a clue why the situation is like that ? I was expecting that the guaranteed memory is the minimum to which the balloon driver will not go bellow, but when I put my host under pressure - the host just started to swap instead of reducing some of the VM memory (and my VMs had plenty of free space). It will be great if oVirt can decrease the memory (if the VM has unallocated memory) when the host is under pressure and the VM cannot be relocated. Best Regards, Strahil Nikolov
