No console with xen-3.2

No console with xen-3.2

[Chuck Short]

Hi,

I installed Xen-3.2 last night and setup the grub.conf and kernel as
usual. However, when I rebooted I did not get an console input when
booting the dom0. I tried adding the console=vga to my grub.conf as
shown below:

title xen-3.2
root (hd0,0)
kernel /boot/xen-3.2.gz console=vga
module  /boot/vmlinuz-2.6.18.8
root=UUID=7373696f-c367-4a6a-b198-17e593508cc8 ro console=tty0
module /boot/xen-2.6.18
quiet

I am not sure where to go from here.

Thanks
chuck

Do you mean you cannot type input at the vga console, or do you mean there
is no output at all? Does output from Xen appear, but not from dom0?

No output at all.

Did the system actually boot, just with no console output, or might the
system simply have been toast?

Also, from where did you get Xen 3.2? Since it doesn't exist yet, did you
pull and build the xen-unstable repo?

Yes it did acutally boot but there was no console output. I meant to
say from the xen-unstable repo.

Are you using the tip of the tree? Could it be a crash? I see it crashing 
(tip) and only the cursor blinking in the upper left corner.

Same to me on one 32-bit system. Two other 32-bit systems and all my
64-bit ones work fine.

Perhaps try no-real-mode on Xen's command line? I would definitely expect
you should get output on the vga display with your current setup.

Re: No console with xen-3.2

[Keir Fraser]

Changesets 16215, 16156, 16147 have to be suspected. Could one of you try
backing those out one by one (cumulatively, not individually) and see if Xen
springs back to life? My fear is that shifting the location of the boot
trampoline has screwed us on some boxes. But then again I have no reason to
think that 0x8c000 isn't a safe place to stick the trampoline...

 Thanks,
 Keir

16215 appears to be innocent - it's sufficiently isolated for reverting alone.
The others I'll try tomorrow, unless Stefan beats me.

In any case - setting a video mode works, so the problem is likely on the
return path from real mode.

So I have tried the following versions and hope I did not do anything 
wrong on the way:

16146  works
16147  works
16156  works
16215  works
16300  does not work

So, it would take me ld(85) more tries to hopefully find the CS that 
caused it. Any hints, though?

Oh, you¹re just doing Œhg update <changeset>¹? You could use binary chop in
the range 16215-16300. :-) I¹ll have a quick look and see if any changesets
are very suspect in that range.... 16287,16266,16259,16249. I think you¹re
best off doing a binary chop. It should only take you half a dozen tries.

On my machine 16259 causes the crash, 16258 still works.

Okay, thanks. To be clear, it crashes for you with no console output at all?
Is that over serial line, or on vga? If on vga, is it text mode or vesa lfb
(the latter is initialised relatively late in boot)?

This is on VGA output. I haven't checked serial line.
The boot entry in grub.conf has only one parameter for xen and that's 
dom0_mem=2G -- must be VGA then?

Yes. It should be the Œtraditional¹ crappy lo-res text mode. That gets
initialised early.

Oh, I see I put in an unconditional MSR_EFER access early on. Not all
systems will have that.... Ooops, will fix.
