vkernel crash?


From: Mike Wolman <mike@xxxxxxxxx>
Date: Sun, 18 Mar 2007 16:09:29 +0000 (GMT)

Hi,

I was having an little play with vkernels - pretty much followed the man page -
except i was using vn1 and not vn0 for the file system.

After doing some scping and other network related testing i closed my xterm
controlling with the vkernel console in it by mistake - i was also logged into
the physical machine via another ssh and pretty much as soon as i closed the
xterm all connections to the main dfly box were lost as well and i am now
unable to ping or see it on the network (the machine had been up for the last 4
or 5 days after and rebuild to 1.9-dev via cvsup on wednesday from a fresh 1.8
install).

Unfortunately i am not in the same location as the machine at the moment
so cannot tell if it has produced a proper crash or has just thrown the machine
off the network.  However i guess this should be pretty easy for anyone to
reproduce - simply start a vkernel from a ssh login and terminate the ssh
connection.

Should vkernels be able to run in a 'headless' mode and any messages be
directed to a file?

Mike.
ps Fortunately i had done a ps previously in the other xterm and also a dmesg:
