When we added partition support to the ubd driver, the minor numbers changed.
You apparently aren't using devfs, so you have /dev/ubd7 == (98, 7), which
is now device 1, partition 7, which would be /dev/ubda7 in the common naming
scheme. Your ubd7 is now (98, 112), so if you mknod that, you should be
able to swapon it.
What we need to do (and I haven't updated the docs to reflect this) is to
switch from the ubd[0-9] scheme to the ubd[a-z][0-9]+ scheme, so that ubd0
becomes ubda1 (assuming that a non-partitioned device is considered to have
one partition, which seems reasonable).
