I've pushed this one already, so this is just 'FYI'. I tested it first on 5 different machines with: - latest upstream qemu - qemu-kvm from Fedora that contains the patch to fix the broken -machine option - qemu-kvm from Fedora, but with that patch removed - old qemu that predates the -machine option entirely - Debian 6 + qemu 0.14 Rich. -- Richard Jones, Virtualization

https://bugzilla.redhat.com/show_bug.cgi?id=619334 This is a slightly unsatisfactory patch which allows coredumps to be captured when they occur inside the appliance. You can capture coredumps by doing: export LIBGUESTFS_COREDUMP=/sysroot/core.%t.%p.%e or equivalently: g.set_coredump ("/sysroot/core.%t.%p.%e") or variations thereof, see the manual page. When a coredump occurs,

qemu <= 0.10 randomly adds a CD-ROM device to the appliance because of this bit of code: http://git.savannah.gnu.org/cgit/qemu.git/tree/vl.c?h=stable-0.10#n5495 Thankfully this code has been removed from upstream qemu. Anyway I'm not quite sure why we never saw this before - it seems like this code didn't exist in the versions of qemu that were in Fedora, or somehow this code only

This patch isn't very elegant, but it should be a conservative change that has the least chance of breaking something else.

This patch also contains some code cleanup, error message fixes, and a regression test. However the pertinent change appears to be this one (which I don't fully understand): - return fwrite (buf, len, 1, fp) == 1 ? 0 : -1; + return fwrite (buf, 1, len, fp) < len ? 0 : -1; Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-df lists disk usage

Couple of notes: (1) You may need to 'make clean' after applying this patch. There is some missing dep so it seems the appliance isn't fully rebuilt. (2) [Comment mainly directed to Matt] This is not a candidate to be automatically added to the stable 1.2 branch. It's far too large of a change for a stable release. Since this change may be required for V2V, please clone
