Re: [Kimchi-devel] [PATCH] Doc: add work around to handle NFS root squash problem

From: Royce Lv <lvroyce(a)linux.vnet.ibm.com&gt; Tested: 1. make 2. nfs pool and vm creation Default NFS server export path is configured as root squash, mapping root user to nobody. This results: 1. Root user cannot step into mount point if export path does not allow other to read/execute. So create volume will fail. 2. Even with other permission open, owner/group of volume created by root is still nobody/nogrp, and qemu permission is denied on such img. This work around instruct user to enable squash to given libvirt user to address the above problems.
