NFS sharing and mounting problem on KVM Debian VM
 
I want to share a folder with nfs in my debian VM which is in KVM hypervisor. I did axactly the same as this site

but when I use this command to make my share point effect I get this error:
Quote:
# cat /etc/exports
/var/result *(ro,sync,no_subtree_check)
Quote:
#exportfs -a
exportfs: /var/result does not support NFS export
/var/result is empty . and in the client side I got this :
Quote:
mount 192.168.0.12:/var/result /home/result/
mount.nfs: access denied by server while mounting 192.168.0.12:/var/result
I tested this configuration exactly on same machine (but bare metal) and everything worked fine.
does any body know what is wrong?

Which nfs version are you using?
What are the permissions on the folder /var/results?
Have you tried exportfs -r (to refresh or empty cache and bring in new settings)?
When mounting also try using the -v to get more verbose output on the client side.

yes I have tried exportfs -r many times

as you see I use aufs as my root partition format could be a cause of it or not ?
if it is how can I override it?

Hi

Can you check your NFS service status??

here you are:
Quote:
# /etc/init.d/nfs-kernel-server status
nfsd not running
# /etc/init.d/nfs-common status
all daemons running

sorry last post was my mistake but this is their statuses again:
Quote:
# /etc/init.d/nfs-kernel-server status
nfsd running

# /etc/init.d/nfs-common status
all daemons running

# exportfs -av
exporting *:/var/result
exportfs: /var/result does not support NFS export
# exportfs -rv
exporting *:/var/result
exportfs: /var/result does not support NFS export

~# cat /etc/exports
# /etc/exports: the access control list for filesystems which may be exported
# to NFS clients. See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check)
#
/var/result *(ro,sync,no_subtree_check)
