Comment 7 for bug 1823676

@Leonardo - thanks for the backport, but this patch won't help.
The reason is that it applied to
 https://git.launchpad.net/ubuntu/+source/libvirt/log/?h=ubuntu/bionic-devel
as-is, but this is before all the patches in
 https://git.launchpad.net/ubuntu/+source/libvirt/tree/debian/patches?h=ubuntu/bionic-devel
are applied.
Among other things this applies:
 https://git.launchpad.net/ubuntu/+source/libvirt/tree/debian/patches/stable/0027-Pass-oldDev-to-virDomainDefCompatibleDevice-on-devic.patch?h=ubuntu/bionic-devel

Due to that I can't take the patch as-is but need to backport it on my own.
Somewhat noisy but it should work.
