virt-install fails on bionic

[Frank Heimes]

virt-install does not work on bionic and ends up with python error:
$ sudo virt-install -d --name ubu-test1 --vcpus 2 --memory 2048 --disk size=8,bus=virtio,format=qcow2 --boot cdrom,hd --network bridge=virbr0 --graphics none --console pty,target_type=sclp --location /var/lib/libvirt/images/bionic-server-s390x.iso --initrd-inject=/var/lib/libvirt/images/preseed.cfg --extra-args="locale=en_US auto=true priority=critical s390-netdevice/choose_networktype=virtio netcfg/use_autoconfig=true netcfg/disable_dhcp=false netcfg/get_hostname=ubu-test1 netcfg/get_domain=domain.com network-console/password=instpass network-console/start=true file=file:/preseed.cfg"

TL;DR - it needs isoinfo but is not part of the dependencies yet.

Pushed to Bionic.
We are late, so it needs an approval of the release team now.

This bug was fixed in the package virt-manager - 1:1.5.1-0ubuntu1

---------------
virt-manager (1:1.5.1-0ubuntu1) bionic; urgency=medium

  * d/control: virtinst needs isoinfo to introspect images. To fix that
    add a dependency to genisoimage to virtinst (LP: #1763609)
  * Merge with latest upstream stable release (LP: #1763618):
    - Fixes potential crash with libxml2 error callbacks
    - Fixes disk/net/mem VM graphs
