Hi all,
I'm facing always the same problem (described below) trying to create a
Xen guest domain on rockpro64 (arm64).
I have successfully built uboot, xen (4.14.4) and dom0 linux kernel with
xen tool stack, these two last starting from buildroot (with linux
kernel version 5.15.33 and xen toolstack version 4.14.4)
These are the process of Xen:
177 root /usr/sbin/xenwatchdogd 30 15
203 root /usr/sbin/xenstored --pid-file /var/run/xen/xenstored.pid
208 root /usr/sbin/xenconsoled --pid-file=/var/run/xen/xenconsoled.pid
214 root /usr/lib/xen/bin/qemu-system-i386 -xen-domid 0 -xen-attach
-name dom0 -nographic -M xenpv -daemonize -monitor /dev/null
-serial/dev/nul -parallel/dev/null -pidfile/var/run/xen/qemu-dom0.pid
and the drivers loaded as a module:
# lsmod
Module Size Used by Tainted: G
xen_netback 65536 0
xen_blkback 49152 0
Xen and dom0 Image boot up successfully, at the end:

when I try to create a domU domain I have problem with disk backend, I
have made several attempts trying with different domU linux and I always
get the following error :
================================================
Parsing config from ./alpine_xen_domu.config

libxl: error: libxl_domain.c:1063:domain_destroy_cb: Domain

================================================
The last try was with alpine domU linux with the following config:
================================================
# Alpine Linux PV DomU
# Kernel paths for install
kernel = "/home/xen/vmlinuz-virt"
ramdisk = "/home/xen/initramfs-virt"
extra="modules=loop,squashfs console=hvc0"
# Path to HDD and iso file
disk = [ 'format=raw, vdev=xvda, access=w, target=/data/a1.img',
'format=raw, vdev=xvdc, access=r, devtype=cdrom,
Have you tried to remove cdrom from your DomU config? I am not sure
cdrom can work well for Arm without device model.
Cheers,

thanks a lot in advance
