--- Comment #27 from Paolo Bonzini (bonzini@xxxxxxx) ---
No, I cannot reproduce it.  From the logs, it seems to be a deadlock between
two callers of smp_call_function, KVM and seccomp, but it's not clear what the
two are waiting (interrupts are enabled).

It's possible that a workaround is to pin QEMU's VCPU thread to one host VCPU. 
If you're using libvirt, this is easily done by modifying the virtual machine's
XML.
