# this script is used to setup the hypervisor for KVM installations.
|
|
# In order for this to work, you have to do the following:
|
|
#
|
|
# 1. In your install template, make sure you add the following
|
|
# to your packages list :
|
|
# bridge-utils
|
|
# dnsmasq
|
|
# iscsi-initiator-utils
|
|
# kvm
|
|
# libvirt.x86_64
|
|
# gpxe-kvm
|
|
#
|
|
# 2. In order to get those packaes, you'll need to add the
|
|
# xCAT-dep repo. For our test we added the line:
|
|
# repo --name=xcat-dep --baseurl=http://#TABLE:noderes:$NODE:nfsserver#/install/xcat/xcat-dep/rh5/#TABLE:nodetype:$NODE:arch#
|
|
# This line can be added after the url --url <blah> line
|
|
#
|
|
# Once you have that, then the following scripts just set up kvm
|
|
# When the machine boots the first time you'll know it works if you can
|
|
# run the command:
|
|
# virsh list
|
|
# You'll then see output like:
|
|
# Id Name State
