In https://access.redhat.com/site/documentation//en-US/Red_Hat_Enterprise_Virtualization/3.2/html/Developer_Guide/Virtual_Machine_CD-ROMs_Sub-Collection.html , the last examples says: "The API changes the CD-ROM for the current session only using a PUT request with an additional current URI argument: Example 14.24. Changing a CD-ROM file during a current session POST /api/vms/cdc0b102-fbfe-444a-b9cb-57d2af94f401/cdroms/00000000-0000-0000-0000-000000000000?current HTTP/1.1" the '?current' in the last line should be ';current' Both are working, but '?current' is deprecated, and ';current' is the recommended method now.
Topic changed 's/000?current/000;current/' Example 14.24. Changing a CD-ROM file during a current session now reads: POST /api/vms/cdc0b102-fbfe-444a-b9cb-57d2af94f401/cdroms /00000000-0000-0000-0000-000000000000;current HTTP/1.1 Change can be viewed here: http://documentation-devel.engineering.redhat.com/docs/en-US/Red_Hat_Enterprise_Virtualization/3.3/html/Developer_Guide/Virtual_Machine_CD-ROMs_Sub-Collection.html
