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 Steve Reichard 2011-05-31 18:21:13 UTC 
Description of problem:
We have always kept our our collections of ISO we we install guests on an NFS share.  This was not previously an issue, however on a RHEL 6.1 hosts this will fail and required me to copy the ISO locally.


If the NFS is mount using NFS3 I see this error:
Unable to complete install: 'internal error process exited while connecting to monitor: char device redirected to /dev/pts/6
qemu: could not open disk image /pub/kits/os/Fedora/14/x86_64/Fedora-14-x86_64-DVD.iso: Permission denied
'

If it is mounted NFSV4, I see this:

This is the same problem as Bug 702044 - chown returns EINVAL for this failure, but we're only ignoring EOPNOTSUPP, EPERM, and EROFS. My guess is that chown previously returned one of these other errors, but has been changed for some reason.
