[one-users] Xen Paravirtualized error - cfg and template

Tue Sep 10 08:04:47 PDT 2013

Same as context, use TARGET in the DISK attribute

DISK = [ IMAGE="CentOS-root" , TARGET="sda1" ]

Probably, setting it at the image level is a better idea as the TARGET
value is inherited from there. So update the image template and simply add

TARGET=sda1

to it.

Cheers
