[PATCH 0/2] Xen PV on HVM multiple PV consoles

[PATCH 0/2] Xen PV on HVM multiple PV consoles

[Stefano Stabellini]

Hi all,
this small patch series achieves two goals:

- make PV consoles work for PV on HVM guests;

- implement support for multiple PV consoles for PV and PV on HVM guests.

Stefano Stabellini (2):
      hvc_xen: support PV on HVM consoles
      hvc_xen: implement multiconsole support

[PATCH 2/2] hvc_xen: implement multiconsole support

[stefano.stabellini]

From: Stefano Stabellini <stefano.stabellini@eu.citrix.com>

This patch implements support for multiple consoles:
consoles other than the first one are setup using the traditional xenbus
and grant-table based mechanism.
We use a list to keep track of the allocated consoles, we don't
expect too many of them anyway.

Does it possible to apply only this 2 patches on stable-2.6.32.x and get
working serial consoles?

I backported the two patches to stable-2.6.32 and created a new branch
that is stable-2.6.32.x + support PV on HVM consoles + implement
multiconsole support:

git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git stable-2.6.32-pvconsole

I still haven't tested it with xend though.

Could you please add CONFIG_DEBUG_INFO=y to your kernel config, so that
we can see the name of the functions in the stack trace?

After add debug kernel not crushed. I'm test more expensive it now. Can
You provide ps auxwww | grep qemu-dm after creating domain with two
serial consoles? (sles does not have libxl, i want to write now wrapper
to qemu-dm, after that try to compile rpm from spec to support libxl).

There is no need for any special command line arguments to qemu-dm, it
is going to create as many PV serials as configured on xenstored by
libxl, give a look at tools/libxl/libxl.c:libxl_device_console_add.
The output of the serial is the one specified on the node "output" on
xenstore.

I reproduce kernel crush:

With attached config file kernel from jeremy stable-2.6.32.x boot ok and
noisy debug info
If i compile with this config from You branch stable-2.6.32-pvconsole
kernel crushed. Nothing displays. Only xm dmesg says:

That's a Xen-generated dump, so that's the best you're going to get for now.

Vasiliy, you'll need to use System.map or gdb to convert the RIP to a
Linux symbol, and ideally go through the stack dump and see if you can
construct a backtrace.

(Dear lazyweb: there ought to be a program/script which can take a Xen
dump and convert the addresses to symbols like ksymoops used to do. 
Somethat that can reformat a Xen dump to a kernel oops for ksymoops
would be a good first step.)

Heh, true. I should have been more careful :)
