I suspect this is down to the ancient version of KVM in RHEL 5. Perhaps it doesn't override aspects of the network configuration such as the host IP address when using -net user,vlan=0,net=169.254.0.0/16
In fact even worse than that ... this old version of qemu ignores the net=... parameter completely! $ rpm -qf /usr/libexec/qemu-kvm kvm-83-164.el5 $ /usr/libexec/qemu-kvm -hda /dev/zero -net user,net=foobar open /dev/kvm: No such file or directory Could not initialize KVM, will disable KVM support Warning: vlan 0 with no nics Could not initialize SDL - exiting Versus on Fedora that command exits with an error status unless 'net=' is a valid parameter. (Actually, there is no error message, but that seems to be a different bug ...) Conclusion: This fix is not supportable on RHEL 5. and we will have to hope that no one tries to use virt-v2v when they have machines using the 10.x network (or provide another workaround for RHEL 5). I'm still interested -- does this patch work on a recent Fedora?

I'm confirming that libguestfs-1.3.9-1 containing two patches referenced above works on recent Fedora.
Those patches are both upstream, so closing.
