We allow you to inspect the guest to find the OS version, and even versions of individual packages installed in it. Using this you can make rules like "only apply grub-install to Fedora guests <= version 15", or "only to guests that have grub version between 1.A and 1.B". http://libguestfs.org/guestfs.3.html#inspection Rich. PS. Also orthogonal to this discussion: It turns out that virt-v2v doesn't use grub-install. However virt-v2v still needs some development work to support grub2 configuration. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones libguestfs lets you edit virtual machines.
