RE: Detecting xen

I  understand you want to distinguish them, but what do you use that for? Is it for some post install customizations? You will have many more options in the post section instead of the pre section?

Subject: Detecting xen



I have the following in a pre-script to detect whether I am building a xen machine:

set $(list-harddrives)

vx=$(echo $2|cut -d. -f 1 )

if [ $vx -lt 5120 ]; then

        echo 'xen' > /tmp/xen





This makes assumptions based on disk size.

This is a fairly safe assumption for us because we control the disk size but I was wondering if anybody could suggest a more sure fire robust way of detecting whether one is building xen or “normal”. For normal builds I am using dmidecode which is working very well and I can even use it for VMWare builds.


My aim is to have one kickstart per service type that adjust itself according to underlying platform which could be IBM, HP, VMWare or Xen.
