Re: Xen PV drivers for FreeBSD
Hi, Just let you know: everything starts work for me in 8.2-PRERELEASE (RELENG_8) Thank you for your work. I'm also highly interesting FreeBSD paravirtualized DOMU to be stable. I'll build test XEN i386 today. I'll let you know results if you want. --- Yura On Dec 3, 2010, at 3:23 PM, Justin T.

A FreeBSD stable/8 XENHVM kernel from yesterday functions properly for me in my Xen environment. The problem is not with CDROM device, but with boot process stops. Did you remove the CDROM from the device configuration for your domain? My host systems do not have CDROM devices to pass through, so I have not tested the impact of detecting a CDROM device on the FreeBSD XENHVM device probe process. In short, I understand that you are not directly complaining a about CDROM functionality, but my hunch is that the detection of a CDROM device is exposing a bug in the block front driver which leads to a hang during boot. -- Justin ___ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to freebsd-xen-unsubscr...@freebsd.org

I have only tested it on amd64, but I don't know of anything inherent in the PV driver framework that would prevent it from operating on other architectures. Do you know is it stable enough ? It has been quite stable for me. There are still some issues with clock interrupt processing (time going backwards messages on the console at times), but nothing that brings down the system. BTW, my testing has been primarily on -current, but I just merged the latest Xen PV driver support into stable/8, so it should work fine there too. -- Justin ___ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to freebsd-xen-unsubscr...@freebsd.org
