Bumping the priority, because this is one of the recommended ways (and easiest way) to create the USB boot media. Harald - This appears to be a regression of bz#1034327 on EL7. Multipath is grabbing some USB drives, and they can't be mounted. We're passing rd_NO_MULTIPATH (which looks odd on EL7 anyway), 90multipath/multipathd.sh doesn't appear to have a way to disable it on EL7. Can we get something similar to rd_NO_MULTIPATH (rd.multipath=<bool> ?) added to dracut on EL7, or is there a more canonical way to do this? Just as an aside, I also tested this against an image with the udev patch applied to EL7. Same result. The real problem here is multipath. We can not solve this in the scope of RHEV-H, but rely on fixes in device-mapper-multipath, see bug 1155957 (In reply to Fabian Deutsch from comment #6) > The real problem here is multipath.

Created attachment 963722 [details] screen_output_log for comment 9 Due to ycui has given test result for scratch build rhev-hypervisor7-7.0-20141201.0.iso in Comment 9, so i clean needinfo requests in here. Test version: rhev-hypervisor7-7.0-20150112.0.el7ev ovirt-node-3.1.0-0.42.20150109gitd06b7c5.el7.noarch rhev-hypervisor6-6.6-20150112.0 ovirt-node-3.1.0-0.42.20150109gitd06b7c5.el6.noarch Test steps: 1. Use DD to build Flash Driver 2. Boot from usb media and select install or Re-install hypervisor After step2, Could get the rhevh installer console, and also reinstall the above two rhevh iso success.so changed the status into "VERIFIED".

Created attachment 949755 [details] attached Screenshot for console screen.jpg Description of problem: Use dd to create the image dd if=rhevh-7.0-20141006.0.el7ev.iso of=/dev/sdb But using this USB media to install rhev-h 7.0 into hosts failed.(Seen console screen.jpg) Version-Release number of selected component (if applicable): rhev-hypervisor7-7.0-20141006.0.el7ev ovirt-node-3.1.0-0.20.20141006gitc421e04.el7.noarch.rpm How reproducible: 100% Steps to Reproduce: 1. Use DD to build Flash Driver 2. Boot from usb media and select install or Re-install hypervisor Actual results: Machine is left in an unbootable state Expected results: We should get the rhevh installer console. Additional info:
