Bug 983814

I can cause this on a host with kvm-intel (Nehalem CPU), but not on a host with kvm-amd (A10-4600M CPU).

Does the latest F19 kernel make any difference? There were several host freezer/crasher issues resolved recently.

I can't make it freeze again with any reasonable effort. Instead of the host freezing, the guest shuts down. I think the guest was crapping itself and shut down, and the actual shutdown caused the freeze.

In light of this new discovery, I believe this is a duplicate of bug 986049.

Can you post /var/log/libvirt/qemu/$vmname.log ?
And details about the USB device you are using

Do you also need a capture with wireshark?

Didn't made 1.5.1 unfortunately, should show up in 1.5.2.

We also have an abrt bug for this, marking this as a dup of the abrt bug, since that is where most people which are impacted this are (automatically) added to the CC.
