I followed the docs at https://www.ovirt.org/documentation/admin-guide/appe-oVirt_and_SSL/ and all works well from the usual web portal. Went to test moVirt and ran into a snag. It wants to download the CA using http://fqdn/ovirt-engine/services/pki-resource?resource=ca-certificate&am...,

but that's grabbing the old CA issued by the engine rather than my custom CA. What else needs to be changed? I'm sure I can finagle my way to a fix here by telling moVirt to use a custom URL or file, but this looks like a bug in the docs that would probably best be fixed. -- John Florian _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/2DUNW4Y24HW...

Okay, this is what threw me. The docs are written in such a way that I never touch httpd's conf, as if maybe I am not supposed to do that. The docs have me change the target of a symlink and do other swaps and avoids touching the conf, be it intentional or not. I may have inferred too much based on the approach.

So my presumption was that the API should/might continue doing what it did before in providing the correct CA certificate. It would be nice if it did, because entering URLs on a phone is not my idea of fun and the moVirt feature to go fetch this directly is really handy.

So, in my case where Puppet is co-managing my Engine, I take it that it would be acceptable for me to manage httpd's ssl.conf file?

Thanks for sharing. I've opted to take a similar "good citizen" approach with my Puppet handling by leaving ssl.conf as is and just manipulating the symlink and certificate/key files in place with their normal names. It's reassuring to know that what the "rules" are. My usual approach is to have Puppet manage everything to assert my will, but I've always worried that approach could bite me when working with a user-friendly tool like engine-setup so I tend to leave well enough alone on my Engine where I can. > >> So my presumption was that the API should/might >> continue doing what it did before in providing the correct CA certificate. >> It would be nice if it did, because entering URLs on a phone is not my idea >> of fun and the moVirt feature to go fetch this directly is really handy. > Patches (or at least RFEs) are welcome :-) > > Also note that movirt, IIUC, should get from httpd the entire chain of > certs, including the root one (your CA's cert), so in principle can simply > prompt you, asking "Do you want to trust this CA cert?".

You've made an excellent point here that moVirt could do this, but maybe shouldn't. I'd be happy to write up an RFE, but now am hesitant on further reflection. I suppose it depends on why the API exposes the CA (and presumably other) certificate details already. If it gets used primarily by oVirt itself, e.g., compute hosts wanting to obtain these, this isn't needed (apparently) and probably would have little to gain for improved support of a custom web CA. On the other hand, if this API is for all that and general consumption regardless of the need, then this does seem like an opportunity for improvement. In the end I didn't have much luck getting my web cert and CA certs over to moVirt via http as I kept getting a Android error parsing the certificate. I then opted to use my much neglected Google Drive to import it from a "file" instead and that went smooth as butter, even prompting me for a Issuer cert where I gave it my intermediate CA and when beautifully prompted again, my root CA.

I already had the intermediate and root CA certs imported into Android, but it looks like moVirt ignores those as a general trust source.
