Follow the guide below if you need to create a new NFS server to hold DTC-Xen images.

1. apt-get install nfs-kernel-server

2. Create a new /etc/exports with the following details (updated to include the new servers):
/usr/share/dtc-xen-app node00004.gigatux.com(ro,subtree_check,insecure) node00001.gigatux.com(ro,subtree_check,insecure) node01002.gigatux.com(ro,subtree_check,insecure) node49001.gigatux.com(ro,subtree_check,insecure)
/usr/share/dtc-xen-os node00004.gigatux.com(ro,subtree_check,insecure) node00001.gigatux.com(ro,subtree_check,insecure) node01002.gigatux.com(ro,subtree_check,insecure) node49001.gigatux.com(ro,subtree_check,insecure)
/usr/share/dtc-xen-hvm node00004.gigatux.com(ro,subtree_check,insecure) node00001.gigatux.com(ro,subtree_check,insecure) node01002.gigatux.com(ro,subtree_check,insecure) node49001.gigatux.com(ro,subtree_check,insecure)

3. Change /etc/default/nfs-kernel-server to have ''RPCMOUNTDOPTS="--manage-gids -p 4002"''

4. Add the following to /etc/services
rpc.statd 4000/udp
rpc.statd 4000/tcp
rpc.mountd 4002/udp
rpc.mountd 4002/tcp

5. Ensure that /etc/hosts has valid entries as follows:
109.169.0.2 node00001.gigatux.com node00001
109.169.23.39 node00004.gigatux.com node00004
216.66.81.3 node01001.gigatux.com node01001
216.86.154.197 node01002.gigatux.com node01002
85.195.104.226 node49001.gigatux.com node49001

6. Change /root/firewall.sh to have the following under the ''# UDP'' section:
iptables -A INPUT -p udp -s localhost -m multiport --ports 4000,portmapper,2049,rpc.statd,nfs,rpc.mountd -j ACCEPT
iptables -A INPUT -p udp -s node00004.gigatux.com -m multiport --ports portmapper,rpc.statd,nfs,rpc.mountd -j ACCEPT
iptables -A INPUT -p udp -s node01001.gigatux.com -m multiport --ports portmapper,rpc.statd,nfs,rpc.mountd -j ACCEPT
iptables -A INPUT -p udp -s node01002.gigatux.com -m multiport --ports portmapper,rpc.statd,nfs,rpc.mountd -j ACCEPT
iptables -A INPUT -p udp -s node49001.gigatux.com -m multiport --ports portmapper,rpc.statd,nfs,rpc.mountd -j ACCEPT

7. Restart the firewall by running ''/root/firewall.sh''

8. Ensure that the root directories for /usr/share/dtc-xen-os, dtc-xen-app and dtc-xen-hvm have read/execute permissions for all by running ''chmod a+rx'' against them
