I''ve noticed that the VGA console is still not fixed in the 3.0.0 kernel when booting with xen dom0. Is there a patch like with 2.6.39? I could probably take what I used with the 2.6.39, but I was wondering if there was a reason for not including it. Thanks. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Also, I''d love to hear an explanation why it is necessary, or what I have to look out for on the mailing list or the LKML in order to follow the progress with regard to this issue. The problem (blank screen) pops up regularly in the xen-user list too. Also the wiki page about pvops dom0 doesn''t mention this issue. (If I could edit that page, I would add the necessary information to it. Unfortunatly, I don''t really know what the problem is, and what the solution might be.)

It was not sending that to the bootloader correctly, or at all, and so the kernel didn''t see that there was a console. That is what I can tell, just my uninformed opinion. Konrad has a patch that fixes the way that Xen reports the console hardware to the kernel, but it looks as if it didn''t make it into the 3.0-rc1 release. I just went to git.kernel.org and pulled up Konrad''s xen repository and selected the stable/2.6.39.x and looked for the commit entitled "xen: allow enable use of VGA console on dom0" which was on May 31st. I clicked on the commitdiff page and then downloaded the patch from the link at the top of the generated page. I used that patch to enable the VGA console on my dom0, worked like a champ, but I don''t know if there is an issue that kept it from being commited in the mainline. I hope this helped.

I > hope this helped.Thank you for your insight. I think, this is the commit you''re talking about: http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git;a=commit;h=09e5e7caf4eac83c010ec3d209cc3dfbe1444ae0 I will try to apply it to 3.0-rc1. If successful, I''ll talk to Pasi in order to change the Wiki page.

I > hope this helped.No issues. Just missed it in the initial list of patches that went for 3.0. Will be there in 3.1, or you can use the stable/2.6.39.x tree that has that patch and some other ones. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
