Re: [Xen-devel] xenctl returning exceptions (half of the time!)

[Matt Ayres <matta@xxxxxxxxxxxx>]

I do have that. 

[root@xen root]# cat /etc/xenctl.xml
<?xml version="1.0"?>

I'm using the default xen-mynewdom script.


[root@xen root]# cat /etc/xen-mynewdom
domain new
physical grant -psda2
domain start

[root@xen root]# xenctl script -f/etc/xen-mynewdom

Still outputs:

[1] root_device_name = sda2
[1] VFS: Cannot open root device "sda2" or 08:02
[1] Please append a correct "root=" boot option
[1] Kernel panic: VFS: Unable to mount root fs on 08:02


The only place where it is just "sda2" in the physical grant line, and
that is the format which it requires.
