The icount framework relies on TCG availability. If QEMU is built with

/11-tests_avocado_replay_kernel.py_ReplayKernelNormal.test_ppc64_pseries/replay.bin:

Although this was revealed in a specific ppc64 scenario, the TCG check
is being done in the common code inside run_vm() because all archs need
TCG to have access to icount.

Pavel,

Should I take this patch through the ppc tree ?

Nobody has queued it yet, so I think it is ok.

Since these are fixes, I will at end of the week.

Thanks,

C.
