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 Lingfei Kong 2014-09-16 10:04:19 UTC 
Description of problem:
No error messages output if append '--format qcow2' after '-a guest.img', but if i put '--format qcow2' before '-a guest.img', virt-customize will detect the image format and print a error.


Version-Release number of selected component (if applicable):
libguestfs-1.27.43-1.1.el7


How reproducible:
100%


Steps to Reproduce:
1. Create a raw format guest image: rhel6.6.img
2. #virt-customize  --hostname unused -a rhel6.6.img --format qcow2
[   0.0] Examining the guest ...
[   5.0] Setting a random seed
[   5.0] Setting the hostname: unused
[   5.0] Finishing off

3. virt-customize  --format qcow2 --hostname unused -a rhel6.6.img
[   0.0] Examining the guest ...
virt-customize: error: libguestfs error: could not create appliance through
libvirt.

Try running qemu directly without libvirt using this environment variable:
export LIBGUESTFS_BACKEND=direct

Original error from libvirt: internal error: process exited while
connecting to monitor: Warning: option deprecated, use lost_tick_policy
property of kvm-pit instead.
qemu-kvm: -drive
file=/root/rhel6.6.img,if=none,id=drive-scsi0-0-0-0,format=qcow2,cache=writeback,discard=unmap:
could not open disk image /root/rhel6.6.img: Image is not in qcow2 format
 [code=1 domain=10]

If reporting bugs, run virt-customize with debugging enabled and include
the complete output:

  virt-customize -v -x [...]


Actual results:
Step 2 have no message output, it seems virt-customize use auto-detection model even though you append '--format qcow2' at the end of the command line.

Expected results:
Step 2 have a error message output, because you specify '--format qcow2', but guest.img is a raw format file

This is supposed to be fixed in >= 1.27.45.  Please try a more
recent version.

Upstream fix commit b7bdb63d8967762a5b234049c4dda911150cc199.

I test it against libguestfs-1.27.46-1.1.el7


#virt-customize  --hostname unused -a rhel7.0.img --format qcow2
virt-customize: error: --format parameter must appear before -a parameter

If reporting bugs, run virt-customize with debugging enabled and include 
the complete output:

  virt-customize -v -x [...]


So, it is fixed in libguestfs-1.27.46-1.1.el7, thanks for your repair work!

Comment 6 Lingfei Kong 2014-10-22 06:45:14 UTC 
Verify with libguestfs-1.28.1-1.2.el7

Steps to verify:
#virt-customize --hostname unused -a rhel.img --format qcow2
virt-customize: error: --format parameter must appear before -a parameter

If reporting bugs, run virt-customize with debugging enabled and include 
the complete output:

  virt-customize -v -x [...]
#virt-customize --hostname unused -a rhel.img --format raw
virt-customize: error: --format parameter must appear before -a parameter

If reporting bugs, run virt-customize with debugging enabled and include 
the complete output:

  virt-customize -v -x [...]
