Hi,
Hello Chaitanya,
I am Chaitanya, pursuing my master’s degree from Portland State
University in Embedded Systems.
I have started working on Xen Project and I am beginner in this field.
I have followed all the steps which are given in this link –
https://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions/qemu-system-aarch64
https://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions#Building_Xen_on_ARM
1) I have used buildroot(rootfs.cpio) for building Linux.
2) I have succeeded in booting Linux on Qemu (qemu-system-.aarch64)
3) Used make dist-xen XEN_TARGET_ARCH=arm64
CROSS_COMPILE=aarch64-linux-gnu- for cross compiling and getting Xen
binary.
4) My root is root - root=/dev/sda1
May I ask why the root is different from the example in the wiki page?
Are you using a different setup for the disk (e.g no virtio)?
After running the last step UEFI Prompt opens and it gives me this error.
What do you mean? Which last step?
error: no such device: root.
This is coming from UEFI, right?
Press any key to continue...
EFI stub: Booting Linux Kernel...
This is booting Linux and not Xen. It is also trying to using ACPI
rather than DT. Would it be possible for you to drop to the UEFI shell
and try to boot by hand?
EFI stub: Using DTB from configuration table
EFI stub: Exiting boot services and installing virtual address map...

I am unable to find the root cause of this issue. Please can anyone help
me with this.
