rpi5 domain creation problem

[Selina <selina.hbx@xxxxxxxxx>]

Hello, 

I successfully installed Xen on rpi5 using buildroot and uboot. 

However, I'm having trouble creating a domain. 

Here is some information about my system.

# xl create /etc/xen/Dom-u1.cfg

Parsing config from /etc/xen/ /Dom-u1.cfg

xc: error: panic: xc_dom_boot.c:120: xc_dom_boot_mem_init: can't allocate low memory for domain: Out of memory

libxl: error: libxl_dom.c:595:libxl__build_dom: xc_dom_boot_mem_init failed: No such file or directory

libxl: error: libxl_create.c:1577:domcreate_rebuild_done: Domain 1:cannot (re-)build domain: -3

libxl: error: libxl_domain.c:1182:libxl__destroy_domid: Domain 1:Non-existant domain

libxl: error: libxl_domain.c:1136:domain_destroy_callback: Domain 1:Unable to destroy guest

libxl: error: libxl_domain.c:1063:domain_destroy_cb: Domain 1:Destruction of domain failed

Domain configuration file:

name = "dom_U1"

type = "pvh"

memory = 128

vspus = 1

maxvscpus = 1

extra = "init=/sbin/init loglevel=1 console=hvc0"

kernel = "/opt/Image"

ramdisk = "/opt/rootfs.ext4"

bcm2712-rpi-5-b.dts file :

#include "arm/broadcom/bcm2712-rpi-5-b.dts"

/{

          chosen {

                       xen,xen-bootargs = "dom0_mem=512M dom0_max_vcpus=1 loglvl=all dom0_vcpus_pin=1 flash=permissive argo=1";

                       xen,dom0-bootargs = "console=hvc0 root=/dev/mmcblk0p2 rootfstype=ext4 loglevel=7 plymouth.ignore-serial-consoles";

                       bootargs = "console=serial1,115200 console=ttyAMA10 root=/dev/mmcblk0p2  rootfstype=ext4 loglevel=7 plymouth.ignore-serial-consoles";

                       

                       #adress-cells = <2>;

                       #size-cells = <2>;

                       dom0 {

                                      compatible = "xen,linux-zimage", "xen,multiboot-module", "multiboot,device-tree";

                                      reg = < 0x0x0x8800000 0x0 0x02000000>;

                       };

           };

 };

I'm sure I'm missing something. I just wanted to know if this is an issue that has been encountered and resolved before. 

If so, any help would be appreciated!

Thank you and best regards, 

Selina.
