> The existence of such a catastrophic bug shows that Xen is unfortunately not suitable for use as an hypervisor in a secure system and needs to be replaced. What makes this bug a huge deal for me, and probably why it's making the news is that it effects fully paravirtualized guests. There have been many, many bugs for HVM guests (and for KVM guests) since the last PV security hole. (March, was it? xsa-123, I think?)
