Added qemu-devel and debian maintainers to cc for this regression about 
upstream qemu.
If you need more details and tests tell me and I'll do/post them.

As a superficial guess, this could be fixed by the seabios-1.7.3.1 release:

Thanks for reply, i did fast test adding this patch that you linked:
http://code.coreboot.org/p/seabios/source/commit/2a9aeabdfb34374ecac25e7a8d21c9e368618cd4/
Same result, the problem remains, should I test full seabios 1.7.3.1?

No idea, it was just a random shot, sorry... You're probably down to
bisecting qemu :(

I did another test disabling the usb controller: it didn't find any 
bootable disk and tried to boot with pxe. I also tried F12 and it 
reported an hard-disk size of 0 MB.
Configuration is correct because if I change the ram size to 2 GB 
instead of 4, it starts correctly.
No additional information from qemu log.
I tried also seabios 1.7.2.2 and master from git, both with same result.

It's not clear to me if this is a QEMU issue or SeaBIOS issue.  Can
you arrange to run qemu with the following added to the command line:

-chardev stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios

and post the full log from a successful (2G) boot as well as the
unsuccessful (4G) boot?

Tried with qemu 1.4.2 and it works also with 4 gb of ram.
This ram regression seems to be introduced with qemu 1.5, and there is 
another regression more critical with qemu 1.6.

Tried to add seabios debug options to domU xl configuration file...

device_model_args=["-chardev 
stdio,id=seabios","-device","isa-debugcon,iobase=0x402,chardev=seabios"]

But it doesn't boot

Can you save qemu's stderr for the 1.5->1.6 regression?

That's probably because you forgot to break up this option into
separate python list entries:

device_model_args=["-chardev", "stdio,id=seabios", "-device", "isa-debugcon,iobase=0x402,chardev=seabios"]

Thanks for your reply and sorry for my very stupid error.
I retried with the correct parameters and on both cases (2 gb of ram 
working and 4gb of ram not working) I get only this one more line on 
qemu log:
Start bios (version debian/1.7.3-1-1-ga76c6f1-dirty-20130813_122010-test)

The probable cause is that on xen, seabios doesn't generate some tables 
but it takes the static ones from hvmloader.

Without having any specifics in mind, maybe this can be attributed to
the ACPI table move that affects both qemu and seabios, and hvmloader is
the collateral damage. Probably stuff should be updated in qemu/seabios
so that hvmloader be happy again. CC'ing Michael...

Of course I might as well be completely off.

Seems unlikely - the ACPI table move code is still in my tree.

I see on 1.6 changelog:

...
QEMU can expose the full set of ACPI tables to the guest: See 
Features/ACPITableGeneration 
<http://wiki.qemu.org/Features/ACPITableGeneration>
...

Could be this the regression problem of 1.6?

Xen moves the debug port to 0xe9 - can you try again with
iobase=0xe9.  (There should be some way to tell xen to log 0xe9 on its
own, but I'm not familiar with xen.)

Thanks for reply.
I tried with this:
device_model_args=["-chardev","stdio,id=seabios","-device","isa-debugcon,iobase=0xe9,chardev=seabios"]

No more lines in qemu log are written and also "Start bios" line does 
not appair any more.
