No, this:

means that the kernel could not recognize /dev/sda1

(8,1) comes from the major and minor numbers, e.g. :

   [root@am3 ~]# ls -ld /dev/sda1
   brw-rw----    1 root     disk       8,   1 Mar 23  2001 /dev/sda1

this would _not_ be an fstab issue, as the boot process has not
gotten that far yet.

are you _sure_ that "/home/name/vm1disk" is correct? and can you
mount it via loopback (my apologies if this has been covered).

"name" seems pretty generic, I suspect you haven't changed it to
your userid, or updated it for the path on your system?

"unknown-block" sounds bad... like it isn't there, as compared to
being misformatted or the like.
