3) Recreation steps:
i) Prep a guest
ii) Remove in the os section
<boot dev='hd'/>
iii) Add this on your former primary disk:
<boot order='1'/>
iv) And then add the xml content generated with:
echo "" > disk.xml;
for i in {1..24}; do
h=$(printf "\x$(printf %x $((98+$i)))")
echo "<disk type='file' device='disk'><driver name='qemu' type='qcow2'/><source
file='/var/lib/uvtool/libvirt/images/cpaelzer-bionic-t$i.qcow'/><alias
name='virtio-disk0'/><target dev='vd$h' bus='virtio'/><boot
order='$((i+1))'/></disk>" >> disk.xml
qemu-img create -f qcow2
/var/lib/uvtool/libvirt/images/cpaelzer-bionic-t$i.qcow 1M
echo "<disk type='file' device='disk'><driver name='qemu' type='qcow2'/><source
file='/var/lib/uvtool/libvirt/images/cpaelzer-bionic-tb$i.qcow'/><alias
name='virtio-disk0'/><target dev='vdb$h' bus='virtio'/><boot
order='$((i+24+1))'/></disk>" >> disk.xml
qemu-img create -f qcow2
