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 of problem:
The virsh interface allows easy conversion from a volume name and pool id to a volume uuid or volume path, but the conversion is one-way.  libvirtd already provides the interfaces for the reverse direction, from a volume uuid or path back to its containing pool, but virsh does not expose this.


Version-Release number of selected component (if applicable):
libvirtd-0.8.1-7.el6.x86_64

How reproducible:
Always


Steps to Reproduce:
1. virsh vol-create default image.xml # where image.xml describes path/to/image.img
2. virsh vol-pool path/to/image.img
  
Actual results:
unrecognized command - to image.img, you have to already know that it belongs to the pool 'default'

Expected results:
print 'default', since libvirtd can compute the reverse mapping from any path back to the storage pool that would contain it

Any further improvements to vol-pool will be tracked through subsequent BZ, such as bug#605543

Verified with libvirt-0.8.1-27.el6.x86_64 & qemu-kvm-0.12.1.2-2.113.el6.x86_64.
