Hello,

 On my computer (Intel Xeon) commit d8810ad3207e in kvm tree introduces
a segfault when using kvmctl. 

 I'm using kvm commit d8810ad3207e and kvm-userspace commit
d32aaf6d02d1. Everything works fine with kvm commit a78ebcb65fb7fc and
kvm-userspace commit d32aaf6d02d1.

 Here is the problem:

 # ./user/kvmctl user/test/x86/simple.flat 
 Segmentation fault

 Here is the message observed in kernel log:

kvmctl[12615]: segfault at 0 ip 0000000000000000 sp 00007fffef5cd3a8
error 4 in kvmctl[400000+8000]

It's the same with all .flat files. 

Regards,
Guillaume

Confirmed, but I'm unfamiliar with this tool to see immediately what
goes wrong. Maybe just some missing initialization (try_push_nmi calls a
NULL callback).

However, I'm traveling later today and will look into this meanwhile.

Thanks for reporting,
Jan

That was indeed the issue; I committed a fix.
