Re: [Xen-users] [xen-4.6-ARM][Renesas-Lager Board] Fail to enter rootfs on DOM0 after setting XEN

[ììí <charlescho64@xxxxxxxxx>]

Hello,Â

I had tried to get Dom0 shell with simple initramfs. but it was not working on xen.

In case of without-Xen, linux with similar setting(the difference is for bootargs for dom0 and xen) is working well.

I hope, anvody help me to solve about "how to get the shell for DOM0 on lager board"?Â

BR.

By "check network on Xen" I meant testing the network is working in DOM0.

In your test case, you are directly trying to use a filesystem from NFS.
But you don't even know if the network driver is fully working on Xen.

You should try to narrow down your test case in something that don't
involve many drivers. For instance using an initramfs for your rootfs
(see buildroot/busybox). The initramfs doesn't involve neither network
nor the disk.

The first step will be to get up to the shell and then if you can test
network as on baremetal.
