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 Fam Zheng 2013-11-11 12:33:37 UTC 
Create a monolithicFlat VMDK image and use "qemu-img info" to check it, it doesn't detect the correct info:

$ ./qemu-img create -f vmdk -o subformat=monolithicFlat /tmp/a.vmdk 1GFormatting '/tmp/a.vmdk', fmt=vmdk size=1073741824 compat6=off subformat='monolithicFlat' zeroed_grain=off
$ ./qemu-img info /tmp/a.vmdk
image: /tmp/a.vmdk
file format: raw   <--------- This is wrong format detection
virtual size: 0 (0 bytes)
disk size: 4.0K


The cause is the QEMU block layer can't read unaligned bytes in the end of image. (modulo 512 bytes).
Comment 2 Sibiao Luo 2013-11-12 02:22:12 UTC 
Tried with qemu-kvm-0.12.1.2-2.415.el6.x86_64, but did not meet such issue.
fam, did you use the upstream qemu version ?

host info:
# uname -r && rpm -q qemu-kvm
2.6.32-425.el6.x86_64
qemu-kvm-0.12.1.2-2.415.el6.x86_64

# qemu-img create -f vmdk -o subformat=monolithicFlat /tmp/a.vmdk 1G
Formatting '/tmp/a.vmdk', fmt=vmdk size=1073741824 compat6=off subformat='monolithicFlat' zeroed_grain=off 
# qemu-img info /tmp/a.vmdk 
image: /tmp/a.vmdk
file format: vmdk
virtual size: 1.0G (1073741824 bytes)
disk size: 4.0K

Best Regards,

Also tried the qemu-kvm-0.12.1.2-2.415.el6_5.1.x86_64 and qemu-kvm-0.12.1.2-2.415.el6_5.2.x86_64 version that all of them are OK.

Retried it again, this issue is on qemu-kvm-0.12.1.2-2.415.el6_5.1.x86_64 and we fixed it on qemu-kvm-0.12.1.2-2.415.el6_5.2.x86_64.

# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.415.el6_5.1.x86_64

Formatting '/tmp/a.vmdk', fmt=vmdk size=1073741824 compat6=off subformat='monolithicFlat' zeroed_grain=off 
# qemu-img info /tmp/a.vmdk

virtual size: 0 (0 bytes)

Base on above, mark qa_ack+ to it.
