This reverts commit 618e8665db2e4c1a8e9a227045b99b48f6110c06.
This is the first in a series of 10 commits that revert (in reverse
order) the changes to add the <acpi-hotplug-bridge state='on|off'/>
switch to libvirt domain XML, which unfortunately needs to be removed
due to QEMU developers discovering a flaw with the design of the QEMU
commandline switch used to implement the libvirt switch that will
likely result in a new and different method of selecting hotplug
modes. Because the libvirt switch has not been in any official
releases of libvirt, we are still able to remove it completely, rather
than deprecating it.
The original commits began with commit
58ba0f6a3d7342fba29edbbf2bb9cb5497c870e5. The other original commit
IDs are documented in each revert commit.
