RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

trying to install latest rhev6 from PXE (auto install) installation seem to fail on disk partitioning phase when using SCSI\sata disk. 
from debugging issues with Mike, he found that that problem is when using a scsi disk, that generate a multipath device containing spaces, but is specified as /dev/sda (or similar), our translation from /dev/sdX to /dev/mapper/<wwid> was broken causing partitioning to fail.

mike also found that during auto-install, they had no value set for OVIRT_ROOT_INSTALL which caused partitioning to break even more.

there is a problem with error handling as well. 


used the following kernel options: 


rootflags=ro rd_NO_LUKS ro liveimg root=live:/rhev-hypervisor.iso rd_NO_MD local_boot rhgb crashkernel=128M management_server=10.35.115.4:8080 rootfstype=auto storage_init=/dev/sda 

please note that installation from ISO works.

All these issues were fixed as part of 613754.
