[Xen-users] iSCSI root on Dom0

["Joe Royall" <joenukem@xxxxxxxxx>]

I am getting the following error on boot on a new install Centos 51:

#/bin/sh ro no such file or directory
then a kernel panic

I have traced it to the call 'switchroot' in the init script in the initrd.

the exact same build without zen has no problems.

the boot messages look like:

the xen and the noxen have different iscsi partitions and only one is activated at a time.

the xen and noxen kickstarts are the same execpt the xen includes the package @Virtualization

Any ideas?

attached is the anaconda generated init inside initrd.
