Hey Predrag,

If you touch the qemu-kvm bin the host panics immediately and reboots....

Checked that on real hardware (DataON CIB-9470V12, E5-2600 V2, C602)
with current hipster:
illumos-6640c13bea i86pc i386 i86pc
qemu-kvm reboots the host immediately. Seems to be a serious bug.
No panic message, just a reboot, starting in dbx looks like this:
ro sunth7 ~ # dbx /usr/bin/qemu-kvm
For information about new features see `help changes'
To remove this message, put `dbxenv suppress_startup_message 7.7' in your .dbxrc
