Yes. Because some ancient guest [RHEL 3?]'s mkinitrd would only work
under IDE emulation, unfortunately virt-v2v always uses IDE emulation,
so is restricted to 4 disks. 1 or 2 are used for other purposes
depending on how you configure virt-v2v.
This will all be fixed in the rewrite.

virt-df lists disk usage of guests without needing to install any
software inside the virtual machine. Supports Linux and Windows.
