Virtual SME Server

The problem is that your IP is NOT on the same network range as your gateway so we have to fool the system.

	Note:
	WIP. Place holder page for all things related to using SME Server as a virtualized server. Please add any info you feel is useful and someone from the doc team will format it nicely, so please go ahead!

	Skill level: Developer
	Thorough understanding of SME Server, configuration and virualization is required. Do not deploy in a production environment unless you are very confident you have the skills to manage and troubleshoot and find root causes of possible issues.

	Note:
	We need to come up with a template fragment for grub.conf to make kernel options survive events.

	Warning:
	You need a second IP (failover) address. Assign it to your server and make sure you set the MAC for this IP before you do anything else - failure to do so may block your network !! The problem is that your IP is NOT on the same network range as your gateway so we have to fool the system.

	Note:
	Make sure you set your default keyboard - it makes life much easier!!

	Warning:
	The procedures listed here are outside normal SME operation. They are not guaranteed to work. Make sure you fully understand what you are going before proceeding
