Without -o plugin uses username + password authentication (to be compatible with RHEV 3.0, oVirt 3.0 - especially to not break existing setups): $ ./check_rhev3 -H localhost -f authfile -D -vvv [V] REST-API: cookie filename: cmhldm0tYWRtaW5AaW50ZXJuYWwK [D] rhev_connect: Using username and password authentication. With -o a cookie file it uses username + password when the cookie file is missing (first call): $ ./check_rhev3 -H localhost -f authfile -D -vvv -o [V] REST-API: cookie filename: cmhldm0tYWRtaW5AaW50ZXJuYWwK [D] rhev_connect: Using cookie authentication. [D] rhev_connect: No cookie file found - using username and password And uses session cookie if it exists: $ ./check_rhev3 -H localhost -f authfile -D -vvv -o [V] REST-API: cookie filename: cmhldm0tYWRtaW5AaW50ZXJuYWwK [D] rhev_connect: Using cookie authentication. [D] rhev_connect: Using cookie: JSESSIONID=wbYehfrValieFzkv6GBWes-g Please try again with "-o".
