I expected much better speed with a PV Solaris/Nevada under xen, but the opposite was true :( Even taking CPU load into account, at least in my tests, qemu+kqemu was the best combination. All guest OS were either XP or Solaris with 512 MB or 1 GB of ram, out of a total of 2GB. If someone can share a satisfying configuration for a PV Linux or Solaris guest I'll be happy to test it.
