Porting xen on rpi4

[Vipul Suneja <vsuneja63@xxxxxxxxx>]

Hi,

I am porting xen hypervisor on rpi4 with yocto kirkstone sources. Followed the basic steps to build xen-image-minimal & xen-guest-image-minimal. I could flash sd card with xen minimal image & could see dom0 up. I copied "Image", "xen-guest-image-minimal" .ext3 file & guest.cfg to "/home/root". After that created a bridge with below step:

killall -SIGUSR2 udhcpc
brctl addbr xenbr0
brctl addif xenbr0 eth0
killall udhcpc

udhcpc -R -b -p /var/run/udhcpc.xenbr0.pid -i xenbr0 

Could see the xenbr0 interface up.

After that while mounting the guest file system it shows no such file or directory but the file is already there.
