Tried also using v3 in url, this way:

[root at p2vnorasvi1 sbin]# diff fence_rhevm fence_rhevm.orig
84c84
< url += "//" + opt["--ip"] + ":" + str(opt["--ipport"]) +
"/ovirt-engine/api/v3/" + command
---
> url += "//" + opt["--ip"] + ":" + str(opt["--ipport"]) + "/api/" + command
[root at p2vnorasvi1 sbin]#

[root at p2vnorasvi1 sbin]# fence_rhevm -a 10.4.192.43 -z -l "admin at internal"
-p "mypassword"  --shell-timeout=20 --login-timeout=20 --power-wait=10 -v
-o status -n p2vorasvi1
vms/?search=name%3Dp2vorasvi1

<html><head><title>Error</title></head><body>Unauthorized</body></html>

Failed: Unable to obtain correct plug status or plug is not available

[root at p2vnorasvi1 sbin]#
