I am seeing a kernel panic when guest0 is kicked off using the following combination:
- Kernel: 5.4
- QEMU: 6.0.0
- Xvisor: HEAD of xvisor-next
Any idea how to fix this boot option issue?

Hi,
Can you share complete bootlog starting from Xvisor booting to the Linux crash??
Regards,
Anup

Anup,
This is the log from a later run (used latest kernel to try). But the error is the same.

Hi Vysakh,
I tried it at my end and Linux-5.13-rc6 booted fine for me. (see below log)
Can you share the size of your kernel and initrd ?

Hi Anup,
I dug in a bit further. My busybox was not getting compiled. It seems to be an issues with compiling busybox 1.33.1 with the latest toolchain (10.2.0).
In GCC10, RPC is not compiled in by default. The current configuration has NFS mount util enabled and this includes 'rpc.h' which is missing in the latest toolchain. I will send in a patch that disables NFS in the default busybox configuration.
