Hi guys,
I found that some USB disks do not work in QEMU.
I collected seven types of USB disks, and tested them in QEMU. Four of
them can work properly, but other three do not work. I compared their
information in /proc/bus/usb/devices, and found that the four "good"
disks all use endpoint

Hi Lonnie,
Thanks a lot for your help on the UHCI suspend/resume support :-)
I found another problem in QEMU USB support :-(
I have 5 different types of USB disks at hand. Two of them can be used
properly in Linux and Windows XP guest OS. But other three are not.
After issue "usb_add" t
I am using qemu-dm 0.8.2 of xen 3.0.3, and found that use "usb_add"
command to enable some usb disks may cause the guest OS not responding,
while enable other usb disks cause no problem. I searched the archive
but didn't found a similar report. Has anyone met the same problem?
Thanks
Xiaoyang
Hi,
I wrote a patch to automatically eject a physical CD-ROM disk when:
* Issue "eject" command in monitor console, or
* Issue "eject" command in Linux guest system, or
* In Windows guest system, press the right mouse button above CD-ROM
icon, then select "eject".
This is patch is based

I just found that using an older kernel in Fedora Core 4 may “solve” the
problem.
When I tested Fedora Core 4 guest domain, the kernel version I used was
2.6.17-1.2142_FC4, and it cannot recognized the USB disk.
I just changed the kernel in guest domain to version 2.6.11-1.1369_FC4. Then
I am using Xen 3.0.3 with QEMU-DM 0.8.2 on a Intel VT platform. After
insert a USB storage, and use "usb_add" command in QEMU monitor, the
storage should be recognized on guest OS. I tested this with a Windows
XP SP2 guest OS, it doing well.
But when I test the "usb_add" command with some Linu

After add a USB device by "usb_add", I can view it by "info usb". It
shows the bus number and address.
As shown in vl.c, it seems that usb_info() is called when issue "info
usb", and usb_device_add() is called when issue "usb_add".
But if I add call to usb_info() in the end of usb_device_a

Hi guys,
I am using QEMU with Xen and Intel VT, and I have a question about
detecting the CD-ROM disk unmount event: When user ejects CD-ROM in the
guest domain, how can QEMU detect this event?
I know if we use "info block" command before and after a CD-ROM disk is
ejected, we can see the d
