[ovirt-users] Proper way to change and persist vdsm configuration options

Is there a method that works in EL6?
$ openssl x509 -in /etc/pki/ovirt-engine/certs/engine.cer -noout
-pubkey | ssh-keygen -i -m PKCS8 -f /dev/stdin
ssh-keygen: illegal option -- m
$ openssl x509 -in /etc/pki/ovirt-engine/certs/engine.cer -noout
-pubkey | ssh-keygen -i -f /dev/stdin
buffer_get_string_ret: bad string length 813826338
key_from_blob: can't read key type
decode blob failed.
I achieved somewhat similar result by doing the following, though
likely is a security issue having something like Facter read from
/etc/pki/ovirt-engine/keys
$ ssh-keygen -y -f /etc/pki/ovirt-engine/keys/engine_id_rsa
ssh-rsa <PUBKEY>
Thanks,
- Trey
