Hi,
With the below virt-install options, I am trying to import a Realm VM:
[…]
export LIBVIRT_QEMU=/home/realm/qemu-system-aarch64
virt-install --machine=virt --arch=aarch64 --name=test8 --disk
path=/var/lib/libvirt/images/jammy.qcow2,format=qcow2,device=disk,bus=virtio,cache=none
--memory=2048 --vcpu=8 --nographic --check all=off --features acpi=off --import
--os-variant=ubuntu22.04 --qemu-commandline="-M

rme-guest,id=rme0,measurement-algo=sha512" --boot kernel=Image-cca,initrd=rootfs.cpio
You're passing the kernel image file and initrd path as relative paths.
Make sure that it gets interpreted correctly. I suggest always using
full paths, due to the fact that libvirt itself is running the VM from a
separate daemon which might interpret it differently.

However, it fails with the messages:
WARNING Disk /var/lib/libvirt/images/jammy.qcow2 is already in use by other guests
['test', 'tmp1', 'jammy'].
Starting install...
ERROR internal error: QEMU unexpectedly closed the monitor (vm='test8'):

'/home/realm/Image-cca'
Looking at qemu sources this error seems to be reported when it can't
extract the kernel itself from the given file, so check that the kernel
image is correct and an actual kernel image.
Otherwise libvirt simply passes the path to the kernel image to qemu and
doesn't interpret it in any way so from there I'd suggest contacting
the qemu mailing list.
