opengl in windows 7 guest?
by Tom Horsley
I'm trying to get a program to run in a Windows 7
guest, and I get the distinct impression that
opengl simply doesn't work (at least with spice/qxl).
Can anything make this work, or should I just give
up for now? :-).

Where do the machine definitions come from?
by Tom Horsley
I'm upgrading a prehistoric fedora13 machine that hosted
a gazillion virtual machines to centos 7.
I find that the old virtual machine xml files make
the new libvirt barf.
I can get a good idea of how to fix all the old xml
by installing a new file and comparing things, but
I wonder where this magic comes from:
<os>
<type arch='x86_64' machine='pc-i440fx-rhel7.0.0'>hvm</type>
<boot dev='hd'/>
</os>
Specifically, the "machine" definitions. Should that just
always be the string above since my host is centos 7?

Why is name not shown in Add Hardware for USB device?
by Tom Horsley
If I go to "Add Hardware" in virt-manager and select USB host device,
I get a dialog with a list of things similar to lsusb output, but
some of the entries are blank. For instance, lsusb shows:
Bus 003 Device 022: ID 046d:0825 Logitech, Inc. Webcam C270
but the usb device dialog only shows Bus 3 device 22 with no
description for logitech webcam.
Is this a hint that usb passthrough won't work for this?
Certainly if I select the bus 3 device 22 item, I can
attach it, but the Windows 7 virtual machine doesn't
see anything show up.
Anyone gotten a webcam like this to work with qemu?

No direct answer to your question, but explicitly spelling out versions of QEMU, libvirt and virt-manager will be useful for anyone who wants to reproduce your issue.

USB passthrough stopped working
by VISEUR Eric
Hi,
I've just reinstalled a computer with F20 and virt-preview and noticed USB passthrough doesn't work with QEMU/KVM. I add the device using virt-manager.
· The device indeed appears in the XML declaration after I add it;
· Qemu instances are created under the qemu user;
· Qemu.conf wasn't modified;
· The device remains owned by root;
· The VM libvirt log signals a libusb error: libusb requires write access to USB device nodes.
Is it a known problem ?
Thanks in advance.

state of USB pass through?
by Tom Horsley
A long time ago I tried to connect a printer to a Windows
virtual machine via USB passthrough, and it was pretty much
a complete disaster :-).
How is pass through these days? Apparently the matterform
3D scanner I'm expecting to show up someday appears to the
computer like two devices on a hub. One is a webcam, the
other is an arduino serial connection.
I've successfully forwarded arduino serial connections
before as COM ports, but a webcam that needs a USB2
speed connection, I'm not so sure about.
Anyone think the webcam will work with usb forwarding
these days?
Or maybe I should forward the hub and let Windows sort
out the two devices?
