This only happens with official image builds. On boot, a kernel panic happens almost immediately.
When configuring the boot menu for EFI, we extract the CDLABEL from the regular isolinux.cfg. The cdlabel for official builds contains a '.' which our automated builds do not. Because of this '.', the extraction broke causing the commandline to include root=live:CDLABEL= which causes an immediate panic.
verified on 6.3-20120531.0 build,
1. can reproduce on 6.3-20120523.1, boot will run into kernel panic.
2. tested 6.3-20120531.0 with EFI mode, boot from the iso image successfully and after install finished, rhevh boot normal and can login also.
Technical note added. If any revisions are required, please edit the "Technical Notes" field
accordingly. All revisions will be proofread by the Engineering Content Services team.
When the Hypervisor configures the boot menu for EFI it extracts the CDLABEL from the isolinux.cfg file. The entry in the file contains a period ('.'), which is not matched correctly by the regular expression used to extract the CDLABEL. As a result the kernel parameters generated contained an invalid CDLABEL, resulting in a kernel panic. The regular expression used to extract the CDLABEL has been updated to do so correctly.
