Oracle VM Manager offers some compatibility to manage Oracle VM Server Release 3.2, to assist with the upgrade process. Due to changes in authentication mechanisms in Release 3.3, it may be necessary to disable the use of TLS1 for SSL-based authentication during the interim stage where you may have successfully installed or upgraded an Oracle VM Manager instance to Release 3.3, but your Oracle VM Server instances are still running an earlier release.
To do this, you must edit the
/etc/sysconfig/ovmm
file on the Oracle VM Manager host
and set the USETLS1
parameter as follows:
USETLS1=NO
Due to the number of changes in Release 3.3, some features available in Oracle VM Manager may not function as expected if you continue to run your Oracle VM Servers on a previous release of the software. Therefore, it is recommended that this change is used as a temporary feature during the upgrade process.
When all your Oracle VM Servers have been upgraded, you should reset the
USETLS1
parameter to improve Oracle VM
security:
USETLS1=YES
