Xen users - May 2010 - Framebuffer support in dom0

Greetings!

I have installed xen-4.0 with kernel 2.6.32 on a gentoo box.
Everything works perfectly, except one tiny detail.
I do not have X installed on the machine, so I configured the (old,
non-xen) kernel to use a framebuffer, so that I don''t have to cope
with the ugly 80x25 resolution, especially on a 19" display.

Unfortunately, with the xen kernel, dom0 now uses the 80x25 mode and I
can''t seem to get it to use the framebuffer like it did in the non-xen
kernel. I''m usually logging on locally for maintenance from time to
time, and 80x25 is *really* not fun to work with. I don''t want to
install X just because of that.

Any ideas would be greatly appreciated.

Thank you.

Can you configure the xen kernel (possibly by recompiling it) so it
has support for framebuffer?

I usually use ssh for jobs that need large text display or logs.

Hello,

In the end, I found a solution to the issue (you can also check it out
here: http://rpx.kicks-ass.net/?p=7828). It seems that the framebuffer
driver can''t access the videocard, so I had to use uvesafb (userspace
vesa fb driver) instead of the usual matroxfb driver.

Good luck!
