[Qemu-devel] ballooning not working on hotplugged pc-dimm

[Alexandre DERUMIER]

Hello,

I was playing with pc-dimm hotplug, and I notice that balloning is not working 
on
memory space of pc-dimm devices.

example:

qemu -m size=1024,slots=255,maxmem=15000M 

#free -m : 1024M
-> qmp balloon 512M
#free -m : 512M

-> hotplug pc-dimm 1G:

#free -m : 1512M


(This is the same behavior if qemu is started with pc-dimm devices)


qemu 2.1
Guest kernel : 3.12. 



Does it need a guest balloon module update ?

Regards,

Alexandre Derumier
