A the beginning of last week I had to apply a certificate renewal on a RHV 4.4.7 environment.
It is the commercial product but I think pretty similar in behaviour to the corresponding oVirt release. The engine certificate would have expired on 17th of August, so in between 2 and 3 months later.
The command "engine-setup --offline" automatically proposed to renew them. It gave:
"
--== PKI CONFIGURATION ==--
One or more of the certificates should be renewed, because they expire soon, or include an invalid expiry date, or they were created with validity period longer than 398 days, or do not include the subjectAltName extension, which can cause them to be rejected by recent browsers and up to date hosts.

Renew certificates? (Yes, No) [No]: Yes

and then going ahead:

But I don't know the exact number of days under which to get the prompt and if this number is in any way configurable...
