I have a fresh, default oVirt 3.3 setup, with F19 on the engine and the node (after applying the shmmax workaround discussed in separate thread). I followed the Quick Start Guide. I've added the node, and a storage domain on the node, so the Datacenter is now initialized. However, my ISO_DOMAIN remains unattached. If I select it, select its Data Center tab, and click on Attach, it times out. The following messages are are seen in engine.log when the operation is attempted: http://pastebin.com/WguQJFRu I can loopback mount the ISO_DOMAIN directory manually, so I'm not sure why anything is timing out? -Bob P.S. I also note that I have to do a "Shift-Refresh" on the Storage page before ISO_DOMAIN shows up. This is consistently reproducible. Firefox 25.
