[pve-devel] qemu numaX with cpu list not working anymore

[Alexandre DERUMIER]

Looking at libvirt:

    <numa>
      <cell id='0' cpus='0-3,8-11' memory='109550' unit='KiB'/>
      <cell id='1' cpus='4-7,12-15' memory='109550' unit='KiB'/>
    </numa>


-numa node,nodeid=0,cpus=0-3,cpus=8-11,mem=107 \
-numa node,nodeid=1,cpus=4-7,cpus=12-15,mem=107 \


So, it seem that we simply need to define cpus multiple times

I'll do some tests

Objet: [pve-devel] qemu numaX with cpu list not working anymore

Hi, 

user report a bug with numaX: cpus=0;1;2 list. 

https://forum.proxmox.com/threads/how-to-specify-numa-cpus-in-vm-conf.29694/ 

conf 
---- 
numa0: cpus=0;2;4;6,hostnodes=0,memory=4096,policy=bind 

qemu error 
----------- 
kvm: -numa node,nodeid=0,cpus=0,2,4,6,memdev=ram-node0: Invalid parameter '2' 


The qemu 2.1 changelog said: 

http://wiki.qemu.org/ChangeLog/2.1 

"Non-contiguous host CPUs can be assigned to a single NUMA node. Commas in the CPU list have to be escaped, as in "-numa node,cpus=0-3,,4-7" 


So I have tried, with double comma 

but I still have errors: 

kvm: -numa node,nodeid=0,cpus=0,,2,,4,,6,memdev=ram-node0: Parameter 'cpus' expects a uint64 value or range 


I have also try with ";" as seperator, and I have same error. 


Any idea ?
