Comment 1 for bug 2018612

Add some environment details, as we've tagged the kernel component here.

Environment
-----------

This is a nested setup (the default of upstream OpenStack CI): QEMU on KVM (i.e. the level-2 guest is emulated, without KVM acceleration.)

  - Level-0 (bare-metal) host: [We don't know the details of this, as this is provided by the
    cloud provider]
  - Level-1 (L1) guest ("guest hypervisor") kernel: 5.15.0-71-generic
  - [L1] libvirt version: 8.0.0, package: 1ubuntu7.4
  - [L1] QEMU version: 6.2.0Debian 1:6.2+dfsg-2ubuntu6.8
  - Level-2 (L2) guest: CirrOS 0.5.2; and its kernel is the same as the
    associated Ubuntu LTS kernel
