I''m pleased to announce the availability of Windows PV drivers for 32-bit Windows guests. They are officially called "Sun xVM Guest Additions" and they can be downloaded here: https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_SMI-Site/en_US/-/USD/ViewProductDetail-Start?ProductRef=sun-xVM-guest_add-G-F@CDS-CDS_SMI This is an "Early Access" release; some bugs and issues remain and are being worked on. Things are much faster with these drivers than on a pure HVM domain but we haven''t yet analyzed or optimized the performance. A few gotchas to be aware of: 1) Do not use on a domain with FAT-formatted disks; the drivers can cause a blue screen after the first post-install reboot. This is being actively debugged; the bug ID is: 6746380 guest additions crash windows guests with FAT-formatted disks 2) Externally initiated shutdown (e.g. "virsh shutdown" in dom0) has not yet been implemented. Without drivers, an external shutdown causes instant domain destruction. After the drivers are installed, shutdown commands will be ignored. This will be fixed; the bug ID is: 6704506 need shutdown support for windows xenbus driver 3) save, restore, and live migration are not supported in this release. We have this working internally, so expect to see a new version with this capability made available soon. And something which may be useful to some of you: after a reboot, the guest will report its IP address back to dom0 via xenbus. This can be examined from dom0: -bash-3.2# /usr/lib/xen/bin/xenstore-read /local/domain/3/ipaddr/0 10.6.71.204 [This is an uncommited interface so it could change in a future release.] Enjoy! These are long overdue; it took us much longer than I had hoped to jump through all of the required legal and bureaucratic hoops. - Russ ----------------------------------------------------- Russ Blaine | Solaris Kernel | russell.blaine@sun.com
I gave this a shot. The install went pretty smooth (once I copied the installer off of the network drive to the local disk). I don''t have any quantitative numbers, but things certainly feel snappier after the install. Thanks. -- This message posted from opensolaris.org

What dom0/domU combo did you use? Regards, Fajar
I am also using dom0 snv_98 and XP sp3. The pv network device has worked without problems. I did try the GPL drivers on this setup and I never could get the PV network driver to work there at all. -- This message posted from opensolaris.org
GreatGreatGreatGreat! :) Thanks for the great work! Is there any chance that these driers would work on snv_82 and a hvm xp sp2 domU? Or do these drivers need newer Xen? Thanks in advance! A -- This message posted from opensolaris.org
While I don''t know for sure, I would expect them to work with older versions. The Xen api has not been changing much (as far as I know) in xVM. However, you can snapshot your domu and try them to see. -- This message posted from opensolaris.org
Aha, thanks for the info! Will give it a try for sure! -- This message posted from opensolaris.org

CR 6746380 has been corrected in the Sun xVM Guest Additions (Early Access 3) release. When applying the Windows PV drivers, you can now select the FAT or the NTFS disk format in the format dialog install screen.

Hm, that all sounds nice, but still no 64 bit support this is a problem, Microsofts recent server products rely on 64 bit Windows systems (e.g. Exchange). florian Penny.Cotten@Sun.COM schrieb:> CR 6746380 has been corrected in the Sun xVM > Guest Additions (Early Access 3) release. > When applying the Windows PV drivers, > you can now select the FAT or the NTFS disk > format in the format dialog install screen. > > On 02/18/09 12:06, Russ Blaine wrote: >> The link has changed; it has moved to >> >> https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_SMI-Site/en_US/-/USD/ViewProductDetail-Start?ProductRef=Sun-xVM-guestadd-EA3-G-F@CDS-CDS_SMI >> >> >> >> Russ Blaine wrote: >>> I''m pleased to announce the availability of Windows PV drivers for >>> 32-bit Windows guests.
