rhev-apt (can't remember the upstream name of the top of my head) is
just a utility that automatically installs/updates the tools based
on:
- detecting there is an ISO
- detecting the ISO is a rhev-tools iso
- detecting the ISO is properly signed
- run the various installers
so yes, we need to make sure if the converted VM is a windows VM,
there is an ISO (and attach it to the VM).
how/where does v2v get rhev-apt from btw?
Very good question! Both old and current virt-v2v use a binary (added
to the RHEL build) which Matt extracted from rhev-apt, probably an old
version. I have no idea where it comes from, and I doubt it is up to
date.
$ grep RHEV-App libguestfs.spec
Source7: RHEV-Application_Provisioning_Tool_46267.exe
(not sure the newly introduced ovirt windows guest driver iso has
installers yet).
Something we can build from source using the mingw-* chain would be
useful, otherwise we can never add this to Fedora.
