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.

Patch to change the word "hypervisor" to "connection driver" for VIR_ERR_NO_SUPPORT (747 bytes, patch)

Description Osier Yang 2010-05-25 07:41:30 UTC 
Description of problem:
while trying to create volume on ISCSI pool. the error prompt string will be like:

error: this function is not supported by the hypervisor: storage pool does not support volume creation

Actually the storage driver has no relationship with hypervisor, just has relationship with the storage daemons, such as "iscsid".

so the error msg "error: this function is not supported by the hypervisor:"
is not reasonable.

1296     if (!backend->createVol) {
1297         virStorageReportError(VIR_ERR_NO_SUPPORT,
1298                               "%s", _("storage pool does not support volume "
1299                                       "creation"));
1300         goto cleanup;
1301     }

the upper peice of code is from "storage_driver.c".

> error: this function is not supported by the hypervisor: storage pool does not
support volume creation

We just need to change virterror.c and alter 'this function is not supported by the hypervisor' to 'this function is not supported by the connection driver'

Created attachment 417993 [details]
Patch to change the word "hypervisor" to "connection driver" for VIR_ERR_NO_SUPPORT

This is just a trivial patch (2 changed lines) against current git master, changing the error string as per Daniel Berrange's comment.
