These tangible exploits threaten the sanctity of virtualization projects that are so en vogue today with many companies for their server consolidation and power consumption benefits. The volume is getting louder on these exploit tools because every month or so, there are more of them. One of the neatest was outlined in late July at Black Hat 2009 USA.
