Xen Fails to Create DomU on iMX8QM

Hello,

I am trying to work with Xen hypervisor on the iMX8QuadMax platform. I built my Yocto project by following the i.MX_Yocto_Project_User's_Guide section 5.6.11 with adding xen into the local.conf file. Then, I created 3 partitions: The first one is FAT which holds Xen, image and dtb files. The others hold Yocto rootfs files. In the U-boot stage, I boot Xen with 'run xenmmcboot' command and the booting performs successfully. Also, when I run 'xl list' command, I can see the Domanin-0 has started. (xl list and xl info logs are attached.)

After that, I started to follow the i.MX Linux® User's Guide (IMXLUG) section 12.4 to boot multiple OS. In the first step:

1) I unmounted the /dev/mmcblk1p3

2) insmod /lib/modules/5.4.70-2.3.0/kernel/drivers/block/xen-blkback/xen-blkback.ko

3) xl create /etc/xen/domu-imx8qm-mek.cfg

However, first 2 steps performs without any log (I assume that they works), but the xl create command logs some error as given below:

root@imx8qmmek:~# xl create /etc/xen/domu-imx8qm-mek.cfg
Parsing config from /etc/xen/domu-imx8qm-mek.cfg

libxl: error: libxl_domain.c:1058:domain_destroy_cb: Domain 1:Destruction of domain failed

I attached the 'xl list', 'xl info' and the error message that is faced when I tried to create domu. I would be very grateful if you could help me with this.

Regards.
