Dear All,
I was wrong in stating that only one USB device can be passed through
to Windows XP domU at any one time. In making this assumption, I had
passed through the USB optical mouse only and relied on the onscreen
keyboard as a substitute for the physical USB keyboard.
I realized that I couldn't get to the QEMU monitor and issue the
"usb_add host:vendorid:productid" command even after I have vnc-ed
into my Windows XP domU. This is because the VNC server is running
within Windows XP guest operating system.
In order to reach the QEMU monitor and execute the usb_add command,
you have to initialize the vnc server built-in to QEMU, which I did
not previously do so.
So today I have re-configured my Windows XP Home Edition virtual
machine configuration, particularly pertaining to vnc settings.
Here is my WinXP HVM configuration:
#import os, re
#arch = os.uname()[4]
#if re.search('64', arch):
# arch_libdir = 'lib64'
#else:
# arch_libdir = 'lib'
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 3072
# Should be at least 2KB per MB of domain memory, plus a few MB per vcpu.
#shadow_memory = 8
name = "winxphome32"
vif = [ 'bridge=eth0' ]
acpi = 1
apic = 1
disk = [ 'phy:/dev/virtualmachines/winxphome32,hda,w',
'phy:/dev/sr0,hdc:cdrom,r' ]
#device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
#device_model = '/usr/' + 'lib' + '/xen/bin/qemu-dm'
device_model = 'qemu-dm'
#-----------------------------------------------------------------------------
# boot on floppy (a), hard disk (c) or CD-ROM (d)
# default: hard disk, cd-rom, floppy
boot="cd"
sdl=0
vnc=1
vnclisten="<IP address of dom 0>"
vncdisplay=1
vncunused=1
vncconsole=0
vncpasswd=''
#serial='pty'
#usbdevice='tablet'
# onboard
#pci = [ '00:02.0' ]
# nvidia & firewire
pci = [ '01:00.0','02:01.0' ]
vcpus=2
# No passthrough
#gfx_passthru=0
# onboard
#gfx_passthru=1
# nvidia
gfx_passthru=2
# Can only pass through one usb device at a time
usb=1
# USB Unity Green Mouse
#usbdevice = 'host:1bcf:0007'
# USB A1pro Black Mouse
usbdevice = 'host:15d9:0a41'
# USB Keyboard
#usbdevice = 'host:0603:00f2'
# USB Sony IC Recorder
#usbdevice = 'host:054c:0271'
# USB Lexmark X1270 Color Printer
#usbdevice = 'host:043d:00ff'
# USB Lexmark X1270 Photo Scanner
#usbdevice = 'host:043d:007d'
# USB Lexmark X1270 Generic Hub
#usbdevice = 'host:043d:007a'
After I have started Windows XP domU on my Intel DQ45CB, I vnc-ed into
the VNC server built-in to QEMU using my laptop over network. USB
optical mouse was already passed through to WinXP domU as specified in
the HVM config. On the QEMU monitor, I executed "usb_add
host:0603:00f2" to passthrough my USB keyboard. Windows XP domU
immediately detected the presence of the physical USB keyboard.
Now I have both USB optical mouse and USB keyboard passed through to
my Xen-based Windows XP virtual machine.
Sorry Timothy I took so long to figure it out.
