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.

guest rhel5.7 installation error
Comment 3 Dor Laor 2011-09-12 06:58:05 UTC 
Is there some other guest OS that works w/ 2T qcow2?
Did you had enough space on the host? You should have executed the command with werror=stop Please repeat the test with it.

boot guest rhel5.7 64bit with werror=stop option, still have the same issue.  host free space is 64G.

boot guest rhel6.2 fails with 2T size image
Comment 7 Kevin Wolf 2011-12-07 13:00:49 UTC 
Does this even work on real hardware? 2 TB is the maximum size for the MBR partition table, I wouldn't be surprised if at least RHEL 5 just didn't support that.

we have no real hardware that support 2T disk. so i am not sure if it works in real hardware.  Today i tested another scenario.  if i create a 2T-1M size images to install rhel5.7. it works fine.

Probably a guest problem. Closing.
