When trying to connect from another host -> FreeBSD you recieve this error: Disconnecting: Bad packet length. It was suggested that this may have something to do with the fact that Opensolaris doesn't support scatter gather. The way it was explained to me was that domu's are supposed to check whether the dom0 supports scatter gather, but FreeBSD just assumes that it does. I'm going to be honest and say i have no idea what scatter gather is, whether or not this is true or how to fix the issue if it IS. What i DO know is that in hvm mode FreeBSD works, but we all know pvm mode is designed with performance in mind. >How-To-Repeat: Install Opensolaris Install xVM xen Dom0 Install FreeBSD 8.0 hvm Download FreeBSD src build FreeBSD with xen kernel make the changes (/etc/fstab /etc/ttys) required to boot using pvm mode) boot FreeBSD 8.0 with xen kernel >Fix: >Release-Note: >Audit-Trail: >Unformatted:
