[Bug 535147] [NEW] libvirtd can't start qemu:///session domain - failed to set CPU affinity: Operation not permitted

[Chris Bainbridge]

Public bug reported:

Create a domain xml file. There is nothing special required in the VM
description, the following will suffice:

<domain type='kvm'>
  <name>test1</name>
  <uuid>cd224bdf-9b8a-e2f7-ef3b-ae7acfd30c1d</uuid>
  <memory>524288</memory>
  <currentMemory>524288</currentMemory>
  <vcpu>1</vcpu>
  <os>
    <type arch='x86_64' machine='pc-0.11'>hvm</type>
    <boot dev='cdrom'/>
  </os>
  <features>
    <acpi/>
    <apic/>
    <pae/>
  </features>
  <clock offset='utc'/>
  <on_poweroff>destroy</on_poweroff>
  <on_reboot>restart</on_reboot>
  <on_crash>restart</on_crash>
  <devices>
    <emulator>/usr/bin/kvm</emulator>
  </devices>
</domain>

Note that I am not attempting to set CPU affinity anywhere.

Now do:

$ virsh --connect qemu:///session define test0.xml
Connecting to uri: qemu:///session
Domain test0 defined from test0.xml

$ virsh --connect qemu:///session start test0
Connecting to uri: qemu:///session
error: Failed to start domain test0
error: failed to set CPU affinity: Operation not permitted
