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 2014-08-27 08:22:19 UTC 
Converting from ISO to VMDK with subformat=streamOptimized fails:

    $ ./qemu-img convert -O vmdk -o subformat=streamOptimized foo.iso bar.vmdk
    VMDK: can't write to allocated cluster for streamOptimized
    qemu-img: error while writing sector 64: Input/output error
Comment 4 Jeff Nelson 2014-12-16 23:40:43 UTC 
Fix included in qemu-kvm-1.5.3-84.el7
Comment 6 Qian Guo 2014-12-18 01:53:30 UTC 
Reproduce this bug with qemu-kvm-1.5.3-83.el7.x86_64

Steps:
# qemu-img convert -O vmdk -o subformat=streamOptimized driver.iso bar.vmdk


Result:
qemu-img: Could not write to allocated cluster for streamOptimized
qemu-img: error while writing sector 5996: Input/output error


So this bug is reproduced

Verify this bug with qemu-kvm-1.5.3-84.el7.x86_64

Steps:
# qemu-img convert -O vmdk -o subformat=streamOptimized driver.iso bar.vmdk
# qemu-img info bar.vmdk 
image: bar.vmdk
file format: vmdk
virtual size: 18M (18354176 bytes)
disk size: 17M
cluster_size: 65536
Format specific information:
    cid: 1418867462
    parent cid: 4294967295
    create type: streamOptimized
    extents:
        [0]:
            compressed: true
            virtual size: 18354176
            filename: bar.vmdk
            cluster size: 65536
            format: 
# qemu-img check bar.vmdk 
No errors were found on the image.


So accordingly, this bug is fixed.

# qemu-img info bar.vmdk 
image: bar.vmdk
file format: vmdk
virtual size: 18M (18354176 bytes)
disk size: 17M
cluster_size: 65536
Format specific information:
    cid: 1418867971
    parent cid: 4294967295
    create type: streamOptimized
    extents:

            compressed: true
            virtual size: 18354176
            filename: bar.vmdk
            cluster size: 65536
            format:
