you don't have to write entire output of the shell to the file,
all shell commands supports output redirection to file/linux utilities
such as grep/etc. [1],

also in "script mode" printed limited MOTD (without welcome message)
if it still doesn't work for you, please file RFE (though i'm not sure it will make to 3.3)

[1] list snapshots --vm-identifier aaa > snapshots.txt
for more details see http://www.ovirt.org/CLI#Scripting

this is done for create "visual" isolation between bash and ovirt shells,
not sure i understand how it related to the told above, but if you find it
usable, i don't mind.
