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=20
file as:
% echo online > /sys/devices/system/memory/memoryXXX/state
or to be active at boot, add this udev rule in=20
/lib/udev/rules.d/55-ovirt-guest-agent.rules :
SUBSYSTEM=3D=3D"memory", ACTION=3D=3D"add",
TEST=3D=3D"state",=20
ATTR{state}=3D=3D"offline", ATTR{state}=3D"online"
I can't tell you if this works on el6 guest, but why not testing for us ;=
