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

<div>Hi,<br>
<br>
</div>
<div>I am using oVirt 3.6.2 on FC22 box, all-in-one
installation, my purpose is to test it.<br>
<br>
</div>
<div>I am using a simple Desktop : <br>
- one cpu core i5 3550 with 4 cores <br>
</div>
<div>- 2x4 Go of RAM<br>
<br>
</div>
<div>I installed a Centos 6x64 VM with all updates + ovirt guest
agent.<br>
<br>
</div>
<div>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.<br>
<br>
</div>
<div>Hot plug memory does it have something to do with the
underneath hardware?<br>
</div>
<div>or does it depend on the guest OS?<br>
</div>
<div>or something else?<br>
</div>
<div><br>
</div>
<div><br>
