QEMU unexpectedly closed the monitor

[Itaru Kitayama]

Hi,

Executing virt-install with the following options:

sudo 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=1 --nographic --check all=off --features acpi=off 
--import --os-variant=ubuntu22.04 --virt-type kvm --boot 
kernel=Image-guest-cca-v4,initrd=rootfs.cpio,kernel_args='earlycon 
console=ttyAMA0 rdinit=/sbin/init rw root=/dev/vda acpi=off' --network none

receives an error:

Starting install...
ERROR    internal error: QEMU unexpectedly closed the monitor (vm='test8'): 
2024-07-29T06:23:04.717118Z qemu-system-aarch64: could not load kernel 
'/home/realm/Image-guest-cca-v4’

I am not sure how to investigate as the kernel Image (Image-guest-cca-v4) can 
work if it is used directly with the qemu-system-aarch64, like:

sudo qemu-system-aarch64 -kernel Image-guest-cca-v4 -initrd rootfs.cpio -cpu 
host -M virt,gic-version=3,acpi=off -enable-kvm -smp 2 -m 2048M -nographic 
-append 'earlycon console=ttyAMA0 rdinit=/sbin/init rw root=/dev/vda acpi=off' 
-net none

Userland is Ubuntu 24.04, and the host and guest kernels are for the protected 
VM (Realm) execution.
Any help would be appreciated.

Thanks,
Itaru.
