Windows XP on AMD X2

Windows XP on AMD X2

[Franco Spinelli]

After installing XP on my AMD X2 machine using "fast formatting" tip, I 
am now using it for some test.

Some network questions:

- without any "-net" option I get a "user" config, I can see my physical
   gateway and browse internet but I can't see my LAN share - is this
   correct?
- with "-smb /somedir" I get also access to my LAN share - is correct?
- emulated nic is a RTL8109 at 10 Mb/Half Duplex - is correct?

Some disk questions:

- AutocadLT 2007 don't install, stopping after .NET framework
   installation - no CPU and no disk I/O activity but no freeze
   In XP log there is an event with a problem in wuaueng.dll. I have
   already installed this program in a Vmware XP virtual machine
   Using standard qemu without KVM (and  without kqemu) give me same
   result.

Some USB tablet problems:

- mouse is correctly working but is step-moving

Some CD problem

- if there is no CD in drive, XP don't start using a -cdrom directive,
   putting a CD in drive make it to start.

Some performance problems:

- I/O on disk is about 1/3 of Vmware I/O preformance but about 3 times
   qemu performance
- display performance is approx as qemu
- cursor performance (using usb tablet) is as qemu performance
- no network performance for now

Start command is:

bin/qemu -hda vdisk.img -cdrom /dev/hdd -usb -usbdevice tablet -k it
-smb /download -boot c -m 256

You should be able to see your LAN.  Try with an ip address if name 
resolution does not work (\\10.0.0.1\share).

You get access to a directory on the host.  See the qemu manpage for 
details.

Yes (though the speed settings aren't enforced).

In that case it's a qemu problem.  Please inform qemu-devel.

In qemu/hw/usb-hid.c, look for the lines

    /* Temporarily increase usb polling interval to prevent cpu
     * saturation (3 ms is way too often for kvm) */
    0x33,       /*  u8  ep_bInterval; (255ms -- usb 2.0 spec) */

Try to reduce the value from 0x33 to some lower value.  There are also 
some potential interactivity improvements coming up.

Most likely a qemu problem.

  This is normal behavior.  -cdrom expects valid media for inserting
into the vm.  The vm will emulate a cdrom drive by default even if you
leave off -cdrom (the vm will have an empty virtual cdrom tray).  You
can use the qemu monitor to insert media later during the vm session.
ie:

Press ctrl-alt-2 to go to the qemu monitor

(qemu) change cdrom /dev/cdrom

Press ctrl-alt-1 to go back to the guest vga output.

Yes, it is ok using gateway IP address i.e. \\10.0.2.2\

Removing -cdrom switch from qemu invocation and adding cdrom with qemu 
monitor solve the problem. Very strange

Now, using this qemu command line

bin/qemu -hda vdisk.img -boot c -m 256 -redir tcp:3389::3389

I am able to use rdesktop with a better video and mouse performance.
Can I start XP without graphic output or with graphic window closed to 
icone size?

Starting qemu with the -nographic argument should start Qemu without a
graphical console.

Correct.
But Windows XP don't use serial console so, using -nographic, there is 
non possibility to shutdown XP (not possible from a RDP session).

I don't get Qemu Monitor so there is no possibility to change CD or 
mount USB devices

On Windows XP you can use the 'shutdown' command at the command prompt.

shutdown -s

Just use the -vnc option.  This way you can connect to the VGA output if 
you need to using VNC but ues RDP for everything else.

BTW, I assume you're doing something like -cdrom /dev/cdrom (or at least 
the Windows equivalent).

In QEMU 0.8.2, which KVM is based on, there is very poor support for the 
host CDROM device.  This has been improved in CVS though.
