--- Comment #5 from Michael MacLeod <mikemacleod at gmail.com> ---
Issues with checksums on XENHVM kernels and the ability to route traffic
between XENHVM guests are separate. RootBSD appears to use Cisco switches - at
least if the MAC address of the gateway for my RootBSD guest is to be believed.
You wouldn't run the gateway for an entire cloud infrastructure off a FreeBSD
VM regardless.

For the record, I've been using the OSS Xen releases for years, and have never
been able to get PVM (XENHVM) domU to be functional as a gateway - I've either
had to use HVM or setup a separate box as the router. This has been the case
since at least FBSD8 I think, or whenever XENHVM became an option.
