I do a similar thing, but without unionfs.
I use tmpfs for all the directories that have to be read-write (eg.
/dev, /etc), copy their content from the read-only file system to tmpfs
upon the domU startup, and then mount them with "mount --bind" on top
the read-only NFS root image. No issues so far...
