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.

Hi Sluo,

Paste your RHEL7.0 host and qemu-kvm infos in the bz.
Comment 2 Sibiao Luo 2013-09-11 03:47:04 UTC 
host info:
3.10.0-18.el7.x86_64
qemu-kvm-1.5.3-2.el7.x86_64

e.g:....-drive file=/mnt/sluo-win2012-64bit.vhdx,if=none,format=vhdx,id=drive-data-disk,cache=none,werror=stop,rerror=stop -device virtio-blk-pci,bus=pci.0,addr=0x7,drive=drive-data-disk,id=data-disk
Warning: option deprecated, use lost_tick_policy property of kvm-pit instead.
qemu-kvm: -drive file=/mnt/sluo-win2012-64bit.vhdx,if=none,format=vhdx,id=drive-data-disk,cache=none,werror=stop,rerror=stop: 'vhdx' invalid format
/etc/qemu-ifdown: could not launch network script

Best Regards,
sluo
Comment 4 Sibiao Luo 2014-03-04 06:08:31 UTC 
Retried the latest qemu-kvm-rhev-1.5.3-50.el7.x86_64 version that still hit the same issue which did not fix at all.
QEMU will quit and give a more friendly prompt message for users without read-only specified, like: "'vhdx' can be only used as read-only device".

host info:
# uname -r && rpm -q qemu-kvm-rhev
3.10.0-95.el7.x86_64
qemu-kvm-rhev-1.5.3-50.el7.x86_64

e.g:# /usr/libexec/qemu-kvm -M pc...-drive file=/home/my-vhdx-disk.vhdx,if=none,format=vhdx,id=drive-data-disk,cache=none,werror=stop,rerror=stop -device virtio-blk-pci,bus=pci.0,addr=0x7,drive=drive-data-disk,id=data-disk
Warning: option deprecated, use lost_tick_policy property of kvm-pit instead.
qemu-kvm: -drive file=/home/my-vhdx-disk.vhdx,if=none,format=vhdx,id=drive-data-disk,cache=none,werror=stop,rerror=stop: 'vhdx' invalid format

Base on above, re-assign it.

Best Regards,
sluo
Comment 7 Jeff Cody 2014-07-22 18:57:18 UTC 
This is fixed in upstream qemu 2.1 in commit 8f94a6e4, which is a (relatively) clean backport for 7.1.

Since this bz is fixed in qemu2.1, seems we need to update the bz's component to qemu-kvm-rhev.
