Dummynet can provide bandwidth restriction as well as msec-granularity delays on packets being pushed through a pipe. You can glue together multiple pipes (packets go through several pipes with different characteristics). I'm not sure what your virtual machines need to do so I can't comment whether FreeBSD would be useable. >Other conditions I planned on imposing are non-locking NFS (causes a lot o= f=20 >issues here with files at work), Should be OK > and have SUSE 32-bit clients (host OS of choice at work) FreeBSD doesn't have SuSE clients but should be able to run them in its Linux emulation layer. --=20 Peter Jeremy --JYK4vJDZwFMowpUq Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGOdNV/opHv/APuIcRAnJuAJ4nyeUUtuxqKocve2i4iuFSvfrzhACcD/Hr flCBVVzdte4t31oJkjz13vc= =ZGnx -----END PGP SIGNATURE----- --JYK4vJDZwFMowpUq--
