What that 'configure from numa' button does is try to find the numa cell who's available memory amount is closest to the memory requested by the VM. it then builds a cpuset str from all the cpus associated with that cell. it is intended to not generate a cpuset str across multiple cells. so what you are seeing is expected. Closing as NOTABUG, please reopen if I've misunderstood |
Description of problem: For host NUMA there are 4 cell id configuration. Launch virt-manager, Click Generate from host NUMA configuration button, found it only display the vcpu in cell id equal 0. Version-Release number of selected component (if applicable): libvirt-0.9.1-1.el6.x86_64 virt-manager-0.8.6-4.el6.noarch How reproducible: Always Steps to Reproduce: 1. # virsh capabilities ... <topology> <cells num='4'> <cell id='0'> <cpus num='16'> <cpu id='0'/> <cpu id='4'/> <cpu id='8'/> <cpu id='12'/> <cpu id='16'/> <cpu id='20'/> <cpu id='24'/> <cpu id='28'/> <cpu id='32'/> <cpu id='36'/> <cpu id='40'/> <cpu id='44'/> <cpu id='48'/> <cpu id='52'/> <cpu id='56'/> <cpu id='60'/> </cpus> </cell> <cell id='1'> <cpus num='16'> <cpu id='1'/> <cpu id='5'/> <cpu id='9'/> <cpu id='13'/> <cpu id='17'/> <cpu id='21'/> <cpu id='25'/> <cpu id='29'/> <cpu id='33'/> <cpu id='37'/> <cpu id='41'/> <cpu id='45'/> <cpu id='49'/> <cpu id='53'/> <cpu id='57'/> <cpu id='61'/> </cpus> </cell> <cell id='2'> <cpus num='16'> <cpu id='2'/> <cpu id='6'/> <cpu id='10'/> <cpu id='14'/> <cpu id='18'/> <cpu id='22'/> <cpu id='26'/> <cpu id='30'/> <cpu id='34'/> <cpu id='38'/> <cpu id='42'/> <cpu id='46'/> <cpu id='50'/> <cpu id='54'/> <cpu id='58'/> <cpu id='62'/> </cpus> </cell> <cell id='3'> <cpus num='16'> <cpu id='3'/> <cpu id='7'/> <cpu id='11'/> <cpu id='15'/> <cpu id='19'/> <cpu id='23'/> <cpu id='27'/> <cpu id='31'/> <cpu id='35'/> <cpu id='39'/> <cpu id='43'/> <cpu id='47'/> <cpu id='51'/> <cpu id='55'/> <cpu id='59'/> <cpu id='63'/> </cpus> </cell> </cells> </topology> ... 2. Select a shutdown guest in virt-manager, Click Generate from host NUMA configuration button, click Apply button 3. Then the values will display in Default pinning textbox. Check these values are right or not Actual results: It display as 0,4,8,12,16,20,24,28,32,36,40,44,48,52,56,60. Which are all in cell id=0 Expected results: Since this button is about host NUMA configuration, and from the host it has 4 cell id. So I think it should support user to select the cell id (1 or more) or display all the cpu id in all cell id if can not select cell. Additional info:
