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.
