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.
