I am attempting to run Xen on an AMD FX-4170 Quad-Core Processor.
I have installed Fedora 17 to serve as Dom0.

I am finding that Python does not run well on this
configuration. Specifically, "import random" causes the Python interpreter
to terminate with "Illegal instruction". This means that xend and yum will
not run.

I filed a bug under yum [1], but just realized that things work if I
boot Fedora 17 on bare metal.

Under Xen, /proc/cpuinfo reports the following flags:

fpu de tsc msr pae cx8 apic cmov pat clflush mmx fxsr sse sse2 ht syscall
nx mmxext fxsr_opt lm constant_tsc rep_good nopl nonstop_tsc extd_apicid
aperfmperf pni pclmulqdq ssse3 cx16 sse4_1 sse4_2 popcnt aes hypervisor
lahf_lm cmp_legacy extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch
xop fma4 perfctr_core arat cpb hw_pstate

Has anyone had similar trouble?
