Hello,

After some days scratching my head I found that oVirt is probably missing fenceTypes for IBM’s implementation of OpenBMC in the Power Management section. The host machine is an OpenPOWER AC922 (ppc64le).

The BMC basically is an “ipmilan” device but the ciphers must be defined as 3 or 17 by default:

[root@h01 ~]# ipmitool -I lanplus -H 10.20.10.2 root -P 0penBmc -L operator -C 3 channel getciphers ipmi
ID   IANA    Auth Alg        Integrity Alg   Confidentiality Alg
3    N/A     hmac_sha1       hmac_sha1_96    aes_cbc_128   
17   N/A     hmac_sha256     sha256_128      aes_cbc_128

The default ipmilan connector forces the option cipher=1 which breaks the communication.

So I was reading the code and found this “fenceType” class, but I wasn't able to found where to define those classes. So I can create another one called something like openbmc to set cipher=17 by default.

Another question is how bad the output is, it only returns a JSON-RPC generic error. But I don’t know how to suggest a fix for this.

Thanks,
