Sorry for my late response.
Can you connect to API with the Session-ID?
$ cat /var/tmp/<cookie filename>
$ curl -k -b<session-id> -H "Prefer: persistent-auth" -X GET
https://<host>:<port>/api
e.g.
$ cat /var/tmp/cmhldm0tYWRtaW5AaW50ZXJuYWwK
JSESSIONID=9WHnBzrv14LFEvGcUlzGNdpN
$ curl -k -b JSESSIONID=9WHnBzrv14LFEvGcUlzGNdpN -H "Prefer: persistent-auth"
-X GET
https://localhost:8443/api 1. Where to run "cat /var/tmp/<cookie
filename>" ? It's empty on the
client I used for all the tests.
2. At this point I have no choice but to disable the check of the
RHEV-TLV setup. The 77 checks cause the manager to respond slowly, and
it causes (I believe) anomalies, i.e. host goes to non-responsive mode.
The file with the checks I used is attached for review/convenience.
Thanks.
