back to article New Xen vuln triggers Amazon, Rackspace reboot panic redux

Newly discovered vulnerabilities in the open source Xen virtualization hypervisor have once again sent major public cloud companies scurrying to patch and reboot their systems before attackers can pull off a massive exploit. Amazon and Rackspace have both announced that they will need to reboot some of their servers to address …

      As a result they have to use fancy cutting-edge abstracted software based storage mechanisms instead of the tried and tested SAN mechanisms that any sane IT manager would opt for !

      You get what you pay for.

      So a vulnerability in Xen -- an excellent FOSS -- causes massive panic, reboots and disruption of service and by the fourth comment, we are getting snide remarks on the quality of *Microsoft* software...?

      Most fascinating, indeed!
