* Loading FreeBSD in an HVM-domain on Intel-based host with GRUB @ 2008-02-07 8:26 Igor Chubin 2008-02-07 8:34 ` Keir Fraser 0 siblings, 1 reply; 9+ messages in thread From: Igor Chubin @ 2008-02-07 8:26 UTC (permalink / raw) To: xen-devel Hello all, please tell me, is it possible (at least theoretically) to circumvent bug 622 [1] by using GRUB instead of /boot/loader to load FreeBSD kernel? Or it is silly idea: even if we bypass /boot/loader we will not be able to run FreeBSD kernel in a HVM-domain on a Intel-based host for some other reason? As far as I know, GRUB can't load FreeBSD kernel directly, but only can make chainloading using /boot/loader. Certainly, it is not the solution, but there were patches to GRUB that allow to boot FreeBSD directly [2]. I want to try to use it and eliminate /boot/loader from boot process at all. What can you say about this idea?

In that case this is almost certainly fixed in current xen-unstable. And also current xen-3.2-testing.hg tip if you build it with vmxassist=n.
