Losing serial console boot output / sync_console
...tput on boot:
http://lists.xensource.com/archives/html/xen-users/2011-04/msg00340.html
Unfortunately it got no replies.
I was just wondering and hoping if any developers could answer the
following questions:
- Should I open a bug regarding the loss of serial console output on
boot, and;
- Is sync_console as bad an idea as the warning suggests it is?
I get all my serial console output if I use sync_console, but I
haven''t really put the machines under heavy load and would rather
trade off truncated boot messages as opposed to performance under
load.
Cheers,
Andy

Troubles Using the serial console
...the xen0 kernel, it will never boot
(maybe locked due to the xen''s serial bug).

Then I tried sync_console and it worked fine, icblenke from the irc
channel (#xen) told me to report this issue.

xen hg tree from yesterday hangs, when kernel console is directed to ttyS0
Hi,
I am having the following setup:
the kernel displays its messages to vga and to ttyS0. This works without xen.
When I reboot my system with xen with the following options to xen and vmlinuz,
xen.gz com1=115200,8n1 console=com1,vga

the system hangs up while booting the dom0 kernel.
Has anyone such a setup working? The thin is, I want a console on

[PATCH]x86:x2apic: Disable x2apic on x86-32 permanently
x86:x2apic: Disable x2apic on x86-32 permanently
x2apic initialization on x86_32 uses vcpu pointer before it is initialized. As x2apic is unlikely to be used on x86_32, this patch disables x2apic permanently on x86_32. It also asserts the sanity of vcpu pointer before dereference to prevent further misuse.
