Tested-by: Christy Perez <christy@linux.vnet.ibm.com> According to the test output, update isn't supported by my libvirt version (libvirt-1.1.3.5-2.fc20.x86_64 on Fedora 20). I tested this with copy/paste against v4 of my patchset, since git am wasn't going to work with my updates. Regards, - Christy On 08/12/2014 04:53 AM, lvroyce@linux.vnet.ibm.com wrote:

Based on Christy's patchset: [Kimchi-devel] [PATCH v3 1/3] Fix Key Error when editing CD ROM path

When remote iso protocol is not supported by libvirt, even if we work around by qemu command, it will mess up device list logic. So reject this use case.
