Unliked netif devices, there is only one blkif device (that is one 
blk_handle) for all of your vbds within a domain.  There is also only 
one event channel (again, this is different than netif devices).  I'm 
not sure if there are scenarios where you would have multiple blkif 
devices...

Is there some sort of problem with Plan9?  What exact is happening?  The 
above statements are for Linux.  I don't know if things are somehow 
different under Plan9..

Is there an image of Plan9 somewhere?  I'm currently rebuilding my main 
machine and would love to throw a copy of it in the mix and be #4 :-)
