[SOLVED] Memory Hotplug in Linux does not work

[fireon]

Hello,

we would like to use memory hotpluging vor linux guest. But i can get this working now. I've testet with Ubuntu 12.04 (currently needed), 14.04 with CentoOS7 and Debian8. But it will not work for me.
I know: https://pve.proxmox.com/wiki/Hotplug_(qemu_disk,nic,cpu,memory)#Linux_Guests_notes
And modules are loaded. So what I'am doing wrong?
BTW: In windows guest it is working fine.

Thanks and best Regards

Are you sure that your have the udev rule ?

It's running fine on debian8 here. (don't known about ubuntu 12.04, but you really need a kernel >= 3.10)

Oh, sorry, my fault. I completely overlooked the kernelversion. It is working fine now!

Thanks
