There's no technical reason on why this was done this way. It's just that the original PVH implementation inside of Xen was badly designed, and one of the results is the lack of support on AMD hardware. This is not related to FreeBSD at all, Linux has the same exact problem. I'm (together with other people) currently working on removing this (and other) stupid limitation by doing a proper implementation of PVH inside of Xen. This new implementation is ATM called HVMlite. Sadly I can not yet provide an ETA on when this is going to be finished. Once HVMlite is finished inside of Xen FreeBSD will hopefully be able to run on AMD hardware just like it does on Intel one. I will do a HEADS UP once this is in testing state.

I have to use an AMD box. In the meantime: bhyve? Already mature enough? or VirtualBox? ___ freebsd-xen@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to "freebsd-xen-unsubscr...@freebsd.org"
