The current -o kubevirt mode is quite inflexible. You can only specify where to put the disks using -os dir parameter, and it creates disks called name-sda, name-sdb etc. To use this MTV needs to create a directory with symlinks to the actual output disks.

Refer to the kubevirt section of https://libguestfs.org/virt-v2v.1.html

What would be more useful to MTV would be to allow the locations of the disks to be specified. A rough outline of this feature would be to use:

virt-v2v ... -o kubevirt \
    -oo create=false \
    -oo disk=/path/to/first/disk.img \
    -oo disk=/path/to/second/disk.img

with one parameter required for each disk.

Importantly virt-v2v would assume these disks are precreated and not try to recreate them (as it does at the moment).

We'd keep the old -os method for compatibility in case no disk parameters were specified.
