Dear All:
I am using Xen 3.3 on a Fedora 8 machine and failed to start a guest
domain from an exported NFS directory.
The step I follow is as follows
NFS server: 192.168.1.1
NFS client:  192.168.1.201
1: I copy the guest.img, which can be corrected booted on NFS client
to the NFS server.
2: On the NFS server
    mount guest.img  /xen/guest; such that if I do a ls /xen/guest, I
can see all the files under /xen/guest
        Then I exported /xen/guest to the Client
3: On the NFS client side
     mkdir /xen/guest
     mount 192.168.1.1:/xen/guest  /xen/guest
     Do a ls /xen/guest on the NFS client, I can see the files correctly.
Then I changes the xen config file as follows.
kernel="/boot/vmlinuz"
ramdisk="/boot/initrd...."
root="/dev/root"
nfs_server="192.168.1.1"
nfs_root=/xen/guest

When I boot the guest domain, the error is it can not file the
/dev/root, ie., the root file system. Anyone can help me. Thanks.

- Steven
