On this little 1Ghz/1GB Linux Eee PC I am able to run netbsd, openbsd, freebsd,
dragonflybsd, windows XP, Mac OS X, haiku and other systems using kqemu. I can
even run 4 or 5 of these at the same time. It works well. I use this for
testing my software (a programming language), making sure it
erowindow-keepalive loop, and the connection is
hanging there. I checked the slirp's source code, from the packet
between host and qemu, the host connection is reset, and the problem
is the connection between qemu and guest is not correctly closed by
slirp.
I'm not sure this is a slirp bug or something else, any suggestion
would be appreciated.
Thanks.

Hi Stefan,
Thank you for fixi
This patch series aims to improve the speed of qemu-img rebase.
1. Mainly by removing unnecessary reads when rebasing on the same
chain.
2. But also by minimizing the number of bdrv_open calls rebase
requires.

Overall this approach is much more complicated.

Commit 509d39aa22909c0ed1aabf896865f19c81fb38a1 added support for read
only VMDKs of version 3.
This commit fixes the probe function to correctly handle descriptors of
version 3.
This commit has two effects:

Gentle Ping,
Philippe, John?
Just wondering if the series is okay, as Gerd pointed out this series

Add logical geometry variables to BlockConf.

The tests in hd-geo-test are out of date - they only test IDE and do not

Add an interface to provide direct logical CHS values for boot devices.
We will use this interface in the next commits.

Hi,
Maybe we should add:
CONFIG_HOST_BIOS_GEOMETRY=n
to rom/config.seabios-128k and recreate the 128k image?
