xen master: xl create hangs

[Mathieu Tarral <mathieu.tarral@xxxxxxxxxxxxxx>]

Hi,

I'm testing the latest xen master branch 
(d8cb7e0f069e0f106d24941355b59b45a731eabe)
and when I create a domain with xl create, the domain is successfuly created, 
but the command hangs and never returns

After regaining control by sending a CTRL-C, and destroying the domain, I'm 
left with a
(null) domain for some reason.

I wanted to confirm this issue, so I installed xen-hypervisor-4.16-amd64 
package (ubuntu 22.04), and I couldn't reproduce the issue there, xl create 
returns as expected.

This is how I compiled and configured Xen:

./configure --enable-systemd
make -j $(nproc) debball
sudo dpkg -i dist/xen-upstream-4.17-unstable.deb
sudo systemctl enable xen-qemu-dom0-disk-backend.service
sudo systemctl enable xen-init-dom0.service
sudo systemctl enable xenconsoled.service

This is the configuration I'm using to create my domain:

Any ideas what's happening ?

Thanks !
