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.

Section Number and Name: 

Describe the issue: 
Issue:  Thin provisioning kind of feature is not possible in LVM base storage pool. i.e.If we create volume on LVM storage pool with parameters:
--
Capacity:       1.95 GiB & Allocation:     500.00 MiB
--

Further attach it to any vm. Then, size will not increase beyond 500MB. Detailed steps:

---

To summarize, the behaviour which we get is expected. If we want to use thin provisioning kind of feature then we should create directory base storage pool. But, I am unable to see such limitations from RHEL6 Virtualization Administration Guide. Can we add it in "Virtualization Administration Guide" ?

Suggestions for improvement: 
Add limitation of LVM storage pool information in Virtualization Administration Guide.

Additional information:

Closing as CURRENTRELEASE since this is now available in RHEL 6.5 GA.
