It's a crash in the vfat code in qemu. Can you try any of the newer qemu-kvm rpms, like the one from virt-preview, which is based off qemu 0.12?
Comment 3 Tobias Mueller 2010-06-16 13:21:10 EDT
Hey Amit :-)

I've looked through the code on git myself and it seems to have changed to the better.

If you give me an RPM, I'd happily install and test it.
Comment 4 Amit Shah 2010-06-17 00:11:53 EDT
There's a wiki page that details how to use the virt-preview repo:


Does that work? Upgrading to a newer qemu upgrades certain other rpms too, so it's difficult to point to just one rpm.
Comment 5 Tobias Mueller 2010-06-17 08:21:30 EDT
I've installed Fedora 13 and it still crashes: see bug 605202.
Comment 6 Justin M. Forbes 2010-09-02 12:44:03 EDT
This should be fixed with the latest qemu-0.12.5 packages in F13.  Please reopen if this is not the case.
