[Users] (potential bug) After I create a virtual disk I am unable to start a VM - Permissions issue ? The node seems to have no write access to the directory on the NFS server...

[Gary Scarborough]

I am going to guess that the problem is a UID/GID mismatch.  I am guessing
you are using an NFS server just for NFS, its not also the engine server?
When you install the ovirt engine there is a user/group created for it.
UID/GID 36:36 I believe.  If this user and group doesn't match whats on the
NFS
server, then you will get permissions errors.  If they match, ovirt won't
have problems using the storage.  You usually use directory services with
NFS,
like NIS, or directory server, or LDAP, to prevent the issue.  For testing
it may just be easier to do it manually.
