Yeah, NFS mounting has been a little problematic/inconsistent for me. Specifics: 1) My "/content" directory on the hypervisor host has both direct data but also a loop mount of an iso. The iso and its mountpoint both reside inside /content. 2) In the guest, I have tried NFS mounting the shared /content tree. Of course, I have enabled "crossmnt" to allow access to the loop mounted directory. 3) In the guest, I am "sharing" the mounted tree via an Apache virtual host. My problems: 1) automounter and Apache don't seem to like each other. Apache would not "trigger" the mount operation. 2) Now using fstab to mount the top level /content. It mounts. When I "look" from a terminal window in the guest at the tree and the loop mounted directory, both show nicely. But, then after a period of time Apache gets lost again. For some reason I have yet to determine, the loop mounted directory gets "lost" from inside Apache, but will re-appear if I just do an ls of the directory from a terminal window. So, I thought the idea of doing a directory passthrough (which appears to be available in virt-manager in RHEL 7 but cannot get to "work" after I configure it - the VM refuses to start) might be a solution for my NFS/Apache troubles. I know this list isn't the forum for this, but if someone has an idea to a solution to getting NFS and Apache happier with each other, I would greatly appreciate it. --Rob _______________________________________________ virt mailing list virt@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/virt
