Don't put much trust in /proc/cpuinfo on xen kernel. I think (on some
versions) it actually HIDES vmx flag, for the obvious reason of not
letting any userland programs use it. Here's from my system

flags           : fpu de tsc msr pae cx8 apic sep mtrr cmov pat clflush acpi
mmx fxsr sse sse2 ss ht syscall lm constant_tsc pni est cx16 lahf_lm

yet

 # xm dmesg | grep VMX
(XEN) HVM: VMX enabled

Your xm dmesg output looks valid though, and you should enable it in BIOS.
