so... I've been tinkering with KVM again. my desktop is windows, the linux server is remote, so I have a ssh X tunnel running, and XMing running locally, and launch virt-manager. opens fine, shows the VM I created some time ago. I select that VM (which is running centos 6), and 'open', a window opens for a few seconds, then blam, virt-manager exits before I can click on the 'details' lightbulb.
if I run virt-manager --debug, I get the following output after clicking on 'open'...

Try giving the VM a Spice display, instead of VNC, see if that helps.
Also, on Windows try Mobaxterm SSH client, it comes with X server built-in, perhaps it behaves less crappy.

no idea how to do this, I'm a total newb with KVM.
all I actually want to do is attach a USB device to my existing and running KVM, but the instructions for doing this in virtsh are confusing (anything that requires editing XML files tends to give me a headache). specifically, I want the VM 'kfat' to 'own'
Bus 005 Device 004: ID 08bb:2704 Texas Instruments Audio Codec .......
OK, I figured it out, I had to create a .xml file like...
<hostdev mode='subsystem' type='usb'> <source> <vendor id='0x08bb'/> <product id='0x2704'/> </source> </hostdev>
and pass that to virsh attach-device vmname my.xml

Go to virtual hardware details of your VM ( by clicking on the open button after selecting your VM), in that go to display sections and select spice from vnc.

you mean the open button, that if I push, causes virt-manager to exit ?

There is a nice wiki article about using spice:
