[Xen-devel] Query for running Xen on ARM



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 –





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

After running the  last step UEFI Prompt opens and it gives me this error.


error: no such device: root.

Press any key to continue...

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