At least RHEL 6 issues can be fixed server-side generating an ecdsa key...

Previous tightening of crypto defaults caused problems with us

I am particularly interested / worried about sshd from RHEL 5, 6 & 7
for virt-p2v and virt-v2v conversions.  This broke before, requiring
us to advise users to set the global policy for the machine to LEGACY
(thus ironically weakening crypto for everything).

Also I have some ancient network equipment that cannot be upgraded but
needs older ssh protocols.  I can't connect to it from Fedora unless I
set the crypto policy to LEGACY.

Anyway I'm wondering if the SHA-1 change will impact ssh further?
