I never succeded to go until rootfs mount. The VM crashed before
with, sometimes, temporary freezes during the first steps of the installer.
But, this time, with the crash, I got an error in libvirt log file:
kvm: block/block-gen.c:1719: blk_lock_medium: Assertion `!qemu_in_coroutine()'
failed.

Ok. Please tell us the qemu command line you're using.
The VM is currently a mail relay in a production environment. I cannot
do lots of tests for now. But the mail relay should be moved to another
machine in a few weeks, so it will be possible to make tests.
I put the command lines used by libvirt below:
[A] the version that works for a long time
[B] the version with the Debian Installer added
I see that the machine model is quite old (pc-q35-2.8).

Do you have an example of a small command line for a VM with only the debian
installer (on a SCSI CD with lsilogic controler but I can adapt) that allows
me to have a console? I should be able to test that on the host.
I cannot duplicate the VM as it uses kerberos (I do not want to risk
duplicate keytab in parallel). Or the duplicated VM must be launched
without network.
Am I right you're getting different errors from qemu while trying to
install debian-12.7.0.iso and with your VM?
With the VM, the VM fully froze, but I always saw the login prompt in the
libvirt console (opened with virt-manager). I.e., the qemu binary did not
crashed (the freeze was several hour long sometimes before I forcibely
reboot the VM).
With the debian installer, the console temporary frozed before I got
the language selection screen. And, a bit later, qemu crashed with
the provided log message.
Also, did you try qemu 7.2 before - I can guess you used one of its
releases wit bullseye-backports. I'd be interesting to find out
which (at least major) versions of qemu did and did not have this
issue (or two issues).
According to dpkg log (in /var/log), I did the following upgrades:
dpkg.log.9.gz:2023-07-15 20:13:32 upgrade qemu-system-x86:amd64
1:5.2+dfsg-11+deb11u2 1:7.2+dfsg-7~bpo11+1
dpkg.log.7.gz:2024-03-23 15:35:41 upgrade qemu-system-x86:amd64
1:7.2+dfsg-7~bpo11+1 1:7.2+dfsg-7+deb12u2~bpo11+1
dpkg.log.7.gz:2024-03-23 16:29:10 upgrade qemu-system-x86:amd64
1:7.2+dfsg-7+deb12u2~bpo11+1 1:8.2.1+ds-1~bpo12+1
dpkg.log.1:2024-10-28 13:44:24 upgrade qemu-system-x86:amd64
1:8.2.1+ds-1~bpo12+1 1:9.0.2+ds-1~bpo12+1
So, looking at that, I rechecked my data and correct my initial bugreport.
The host was already in bookworm since March, 23th (were I did a bullseye
upgrade followed by a dist-upgrade to bookworm). The last week, I only
upgrade packages within bookworm (and backports for the kernel and qemu
related packages)
That also tells us that the following qemu version were working:
1:5.2+dfsg-11+deb11u2
1:7.2+dfsg-7~bpo11+1
1:7.2+dfsg-7+deb12u2~bpo11+1
1:8.2.1+ds-1~bpo12+1
But 1:9.0.2+ds-1~bpo12+1 is not working.
There's 9.1 currently waiting acceptance/review for bookworm-backports,
too.
