Hi,
the hot add features starts working out of the box from centos 7.2 guest.
On previous el7.x, two ways to do that:
5.2. How to online memory
------------
Even if the memory is hot-added, it is not at ready-to-use state.
For using newly added memory, you have to "online" the memory block.
For onlining, you have to write "online" to the memory block's state
file as:
% echo online > /sys/devices/system/memory/memoryXXX/state
or to be active at boot, add this udev rule in
/lib/udev/rules.d/55-ovirt-guest-agent.rules :
SUBSYSTEM=="memory", ACTION=="add", TEST=="state",
ATTR{state}=="offline", ATTR{state}="online"
I can't tell you if this works on el6 guest, but why not testing for us ;)

Hi,
I am using oVirt 3.6.2 on FC22 box, all-in-one installation, my
purpose is to test it.
I am using a simple Desktop :
- one cpu core i5 3550 with 4 cores
- 2x4 Go of RAM
I installed a Centos 6x64 VM with all updates + ovirt guest agent.
I tried to augment the memory from 1024 to 1536 (+512Mo) it didn't
work I had to shutdown the VM for the change to take effect.
Hot plug memory does it have something to do with the underneath hardware?
or does it depend on the guest OS?
or something else?
Regards.
