This morning one of my freeBSD production machine did crash. Beeing a
VM running under qemu/kvm on an ubuntu linux hardware, I was unable to
get the panic video message issued when the machine crashed. Of course
at the reboot I got a vmcore file in /var/crash, along with core.txt
and info. The file core.txt says:

Unable to find a kernel debugger.
Please install the devel/gdb port or gdb package.

while the info file is:
