RE: solved, Re: [Xen-users] Windows domU doesn't boot

["Artur Linhart - Linux communication" <AL.LINUX@xxxxxxxxxxx>]

Hello,

        I had the same problem. But I do not think, this is related to the 
serial='pty'
setting... In my case this line was remmed out in the configuration, but the
error 
bind() failed
was till there...

The real problem is (at least in my case was) in the specification of
"vnclisten" parameter - this specifies the address where the machine should
"hear" to incomig VNC connections for management of the HVM hosts. If there
is specified an invalid address, then the vnc "server" for that virtual
instance cannot be started, because there fails the bind of the service to
the specified port on specified address. 

This is also consistent with the fact the qemu-dm starts, but then
everything stops and the TCP post is not allocated, what can be seen if
running 
netstat -a -n
 
Michael, is it possible in Your case this was the same and You not only
remmed-out the "serial" oto, bu also repaired the IP address specified in
vnclisten parameter?

        With regards, Archie

Following up to myself in case anybody else finds any of it useful:

Since posting this (and getting an example of a known good Windows xm
config file which didn't make any difference), I've discovered a few
things and gotten a little further.  First I noticed that the qemu-dm
logs for my Windows machine were tiny.  One complete example:

  % cat qemu-dm-177.log
  Watching /local/domain/0/device-model/177/logdirty/next-active
  Watching /local/domain/0/device-model/177/command
  warning: could not open /dev/net/tun: no virtual network emulation
  Could not initialize device 'tap'

I hadn't needed a tap interface for any of my Linux domains.  So I built
and installed the module for dom0, then had to modprobe it by hand. 
That got me past this error and on to:

  [...]
  shift keysym 003e keycode 52
  shift keysym 003f keycode 53
  bind() failed

bind() of what failed?  Well, comparing this to the log for a working
Linux machine, the next thing after all the shift keysym/keycode lines
was "char device redirected to /dev/pts/12".  Right or wrong, that made
me think of serial lines.  My Windows config (but none of my Linux) had

  serial='pty'

...so I commented that out.  Now the qemu log still ends on an ugly
looking line:

  I/O request not ready: 0, ptr: 0, port: 0, data: 0, count: 0, size: 0

...but the Windows install CD has booted!  Hooray!  Now on to seeing if
I can turn this into a working system.
