[pve-devel] [PVE-User] Memory and CPU Hotplug

[Alexandre DERUMIER]

I have test memory and cpu hotplug in a CentOS 7 VM. 
>>Memory works fine, but I only can increase the total among of memory but not decrease. 
Yes, hotplug only for now. unplug is coming in next qemu release 

>>CPU, although I had enable NUMA, I was unable to change the number of cores. 
>>Perhaps I misunderstood the behavior of hotplug features... 
>>If this the case, please can someone help to understand this better?? 

cpu hotplug is not yet implemented in gui. 

I have updated the wiki about how to do it:

Objet: [PVE-User] Memory and CPU Hotplug 

Hi guys 
I have test memory and cpu hotplug in a CentOS 7 VM. 
Memory works fine, but I only can increase the total among of memory but not decrease. 
CPU, although I had enable NUMA, I was unable to change the number of cores. 
Perhaps I misunderstood the behavior of hotplug features... 
If this the case, please can someone help to understand this better?? 
I also set Broadwell as a CPU type, which I do not know if this correct or not... 
Thanks for any help
