Centos 6.x VMs on CloudStack

If you want to create a template for deploying Centos 6 VMs, you need to do a few things to the VM before snapshotting the root volume and converting it into a template:

• yum -y update (of course)
• set the root password to a well known one ("password" comes to mind)
• delete the SSH keys in /etc/ssh/ so on first boot sshd will generate new keys
• rm /etc/udev/rules.d/70-persistent-net.rules
• yum -y install vim :)
• edit /etc/sysconfig/network-scripts/ifcfg-eth0 to look like:
• DEVICE=eth0
• BOOTPROTO=dhcp
• ONBOOT=yes
• TYPE=Ethernet

That should get you going.
