Beating Kasparov was nice, but this is much more difficult.
They are able to work and vote without restriction. That is not true of Christian and Muslim Arabs, living in Israel.
I bet you didn't know that you're incredibly wrong. Any Israeli citizen can vote, regardless of religion. There are currently 14 Muslim members in the Israeli parliament. Muslims study freely in Israeli universities and work in Israeli companies. The same is obviously not true for Jews in most Muslim countries.
I also have to say that for a site that does so much benchmarking, phoronix is incredibly unprofessional. How about error bars on those bar graphs? Are caches cleared before each benchmark? Etc.
KVM does not do paravirtualization, it virtualizes a full x86 processor (with all its overhead)
KVM does not need to do para-virtualization, but it can do para-virtualized I/O to get better performance (see virtio).
They're both Linux only at this point, and Xen effectively runs a forked version of Linux because it isn't, and won't be, upstream.

Redhat et al are doing xen

Once the operating systems handle them well, and application programmers are more aware of these issues, things will be much better in multi-core-land.
