virt CPU hotplugging doesn't work
Last modified: 2013-11-10 10:46:15 EST
Description of problem:
I was following the instructions of the Virt CPU Hotplug test case for the F20 Virtualization test day.
Changing the number of CPUs to 2 and hitting Apply caused no effect in the guest, e.g. the output of 'ls -d /sys/devices/system/cpu/cpu[0-9]' remained '/sys/devices/system/cpu/cpu0'.
I confirmed beforehand that qemu-qa is running in the guest via 'ps axwww | grep qemu-qa'.
I played with virt-manager's CPU allocation a lot, since there is a bug in the display of the current CPU allocation (bug #1016318), but I couldn't get it to work.
Version-Release number of selected component (if applicable):
Thanks for the report. I'm just going to dupe to the UI issue, since it's tough to correctly verify if libvirt is even being asked to do the correct thing when the UI is messed up. After that bug is fixed if you retested that would be greatly appreciated, but I suspect it was just misleading UI.
