That virt-builder users will have to create a configuration file in
order to enable s-m. There is no other virt-customize option where
they have to create a configuration file, except for ones like
'--commands-from-file' and '--password ...:file:...' which are special
cases.

Well, sort of. You can use --password entirely on the command line,
or you can use a file, but the file: option exists because of security
concerns.
(virt-v2v --password-file is not very regular, but was added for VDSM)
My question is, can we make s-m function with just:
virt-builder --sm-credentials foo
virt-builder --sm-credentials foo:password:123456
virt-builder --sm-credentials foo:file:/tmp/secret
(or something in a similar spirit)?
