(not sure if list will accept this ... too much traffic! had to remove myself)

yes this is with 9p2000.L, both host and guests run kernel 3.2.5.  i'm
happy to provide/try additional information/tests if useful.

... is there really no chance of upping the max path?  seems like
config space will be a big constraint, forever :-(

and i'm very much willing to do additional testing for the other
issues as well (i had to revert to qemu-as-root to get passthru
working 100% on rootfs ... ldconfig is kind of critical :-).  are
these known issues?
