Because of the way cyrus works its best to use its local delivery agent.

Try something like this:

virtusertable:
driver = redirect
allow_fail
allow_defer
qualify_preserve_domain
data =

${lookup{$local_part@$domain}lsearch{/usr/local/etc/exim/virtusertable}}
user = mailnull
transport = local_delivery_cyrus

Then in transports do something like so:
local_delivery_cyrus:
driver = pipe
command = /usr/lib/cyrus-imapd/deliver $local_part
group = mail
user = cyrus
return_output
log_output
message_prefix =
message_suffix =

Note: The above transport works for me, but I am NOT doing and virt
domain stuff. However, given your virt domain bit is correct (which it
appears to be) this should work for you.

Don't forget to make sure that the path to deliver is right.
