Hello, Could you please test the following patch, it should fix UUID: https://people.freebsd.org/~royger/0001-libxl-fix-UUID-usage-on-FreeBSD.patch I understand that the netback performance issue is a big handicap, I will try to find some time to look into it, but I have to admit my plate is quite full at the moment and it doesn't look like a trivial issue (like the UUID one). I'm adding Wei to the Cc, he has been working on netfront improvements, so maybe he also wants to take a stab at netback ;). Roger.
