Well, if it's a 4 cores with HT, it should tell you 8. I've never used
Xen 3, but I don't see a reason why switching from 3 to 4 should have
"eaten" 4 cores!

Have you perhaps disabled hyperthreading in BIOS, or anything like that?
What does /proc/cpuinfo say if booting Linux baremetal (i.e., without
Xen)?
