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 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 bug was initially created as a clone of Bug #889276 +++
Description of problem:
When operating within the virsh shell (as opposed to executing single virsh command), error text is often printed with invalid commands or failed operations. However, in one case the 'domblkstat' command does not print any error. Although executing it as a single virsh command does exit(1). This is a devition from it's RHEL 5 behavior where it does print an error message in both cases (command-line and in-shell). The problem has to do with proper handling of empty-string arguments.
Version-Release number of selected component (if applicable):
0.9.10-21.el6_3.6
How reproducible:
100%
Steps to Reproduce:
1. virsh
2. virsh# domblkstat <name> ""
