Hello, Does anybody know something about Xen PV drivers for FreeBSD? As far as I know there are no stable Xen PV-drivers for FreeBSD at the moment. But what about experimental drivers? Please, if you have any information about this, tell it. I think it would be interesting not only for me but for all who runs HVM domains FreeBSD. And the second question. I run FreeBSD in domUs which work on host systems with AMD CPUs only. I could not run FreeBSD in HVM domain on Intel-based host systems. Has anybody successfully run FreeBSD in a HVM domain on Intel-based host? The message [1] describes several FreeBSD kernel options that should be disabled in order to make FreeBSD work in a HVM domain. The message is not directly related to Intel-based host systems, but may be disabling of listed options can help to solve problems with the Intel-based systems too? Thank you!

There''s sourcecode available for a freebsd port to Xen; it probably wouldn''t be too difficult to adapt this to create PV-on-HVM drivers. Might be a good project for a FreeBSD kernel developer wanting to play with Xen stuff.> I think it would be interesting not only > for me but for all who runs HVM domains > FreeBSD.Yes. Of course it''d be nice to get the FreeBSD port finalised, but I think it lacks a developer at the moment.> And the second question. > > I run FreeBSD in domUs which work on host systems > with AMD CPUs only. > > I could not run FreeBSD in HVM domain on > Intel-based host systems. > > Has anybody successfully run FreeBSD in a HVM domain on Intel-based host?The problem with FreeBSD on Intel was that the realmode emulation code currently available was not comprehensive enough to get FreeBSD to boot (maybe it was just the bootloader, but I guess it could have been FreeBSD early kernel code too). Intel is capable of running FreeBSD anyhow, it''s just a software problem which should be resolved eventually. I don''t know if it works yet though, or how fast any development in that area is progressing.

As far as I understand the problem is not with a loader only, otherwise using GRUB instead of /boot/loader we could circumvent it. -- WBR, i.m.chubin _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I don''t think that FreeBSD 7 includes Xen support but there is a branch of the FreeBSD 7 tree available which has Xen support code in it. This may not be up-to-date wrt to the mainline 7 tree, though.> It''s really better ad for me,- > but AFAIK porting is not finished > and there are many restrictions when running- > FreeBSD in PV mode.The port actually worked, I think, but there was integration and cleanup work required to make it suitable for inclusion in mainline FreeBSD. Last I heard, the project was stalled on that. I think the project needs a new maintainer if it''s going to get anywhere. Cheers, Mark -- Dave: Just a question. What use is a unicyle with no seat?
