Hi Barry,

    I too run Fedora Core 2 as a host OS and have recently updated the kernel to 2.6.8.  After reading your message I tested out the install of Qemu that I have set up and all worked flawlessly (I'm using one of the daily CVS snapshots, not 0.6.0).  My qemu command line is:
LD_ASSUME_KERNEL=2.2.5 qemu -hda win98se_hda.img -boot c -cdrom /dev/cdrom -enable-audio -nics 1 -m 512 -n network.sh -monitor stdio -localtime

In answer to your second question, yes it is possible to connect a serial port in qemu to a real serial port; I have posted patches to enable this and others have posted patches to fix bugs we found in the UART emulation along the way.  They're all on this mailing list :)

I run Fedora Core 2 at work and have been using QEMU for about a month 
now.  When I upgraded to 2.6.8, suddenly none of my VMs would start.  Is 
anyone else haveing this problem?  If not, what did you change to get 
them running?  Until it's working, I'm booting into 2.6.7-1.494.

I absolutely love QEMU.  I was saving up to get VMWare, but when I got 
QEMU running, I scratched it off my list of software to buy.  It does 
what I need.  Right now, I'm heavily into web development 
(PHP,MySQL,_javascript_,XHTML) here at work and need to test webpages in 
IE.  As I hate running Windows, it's great to run it in an emulator for 
testing.  When I finish the 4 current projects, I'll be getting into 
embedded programming again and will probably need an emulated serial 
port that connects to a real serial port.  Is that in the works or 
already working?

(after following the 'development schedule' thread...)  I don't find 
QEMU the least bit difficult to figure out (except networking, but that 
will change in time).  The command line options are just fine.  When I 
get the command line for a given VM the way I want it, I just recall the 
command line and add "echo " ... " >> StartVM" to the beginning and end 
and make my own launcher.  So far, I have virtual machines for 98, 2000, 
XP and a playground for Damn Small Linux hacking.  A 'todo' list for 
development and features would be nice, but isn't required IMO.  If I 
get some time, I'd like to look at the code and see what I can 
contribute.  I've never helped with an open source project before...

One question I have:  is there something in the works similar to 
VMWare's virtual network?  Or, does it already exist and just require 
configuration on the host?  I'd love to setup virtual machines running 
Win2k3 and play with site-to-site VPN's.  That's what we run at both our 
branch offices and I'd rather not test on the real servers.
