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

[Matt Ayres <matta@xxxxxxxxxxxx>]

I'm not sure if you saw the mail where I pasted the xenctl.xml config
file and the defaults.  If you look you'll see in both places it shows
"/dev/sda2". 

[root@xen root]# cat /etc/xenctl.xml | grep root
--> <root_device>/dev/sda2</root_device>
<root_args>ro</root_args>
root@xen root]# xenctl script -f/etc/xen-mynewdom
Domain defaults:
   name            XenoLinux
   size            8192
   vifs            1
   domainImage     /boot/xenolinux.gz
   domainInitRD    null
-->   rootDevice      /dev/sda2
   rootArgs        ro
   usrDevice       null
   NWIP            169.254.1.0+

Everything points to /dev/sda2.  The config file, the defaults, and the
kernel "root" argument.  I have no idea where it's getting the "sda2",
which is why i'm asking here.  I've put arrows in front of every line
where it references sda2, all have /dev/ prefixed.
