==Cloning a virtual SME Server==
 +
When you clone a virtual SME server, you might want to reset some unique variables on the cloned machine. Several things (will) have changed like install date and MAC addresses. Visualization platforms will automatically change the MAC addresses of the NIC's for the cloned machine.
 +
 +
After cloning and first boot, log in as root and issue the following commands
 +
config delprop sysconfig SystemID
 +
config setprop sysconfig InstallEpoch `date +%s`
 +
rm -f /etc/udev/rules.d/70-persistent-net.rules
 +
Then run the console application and reconfigure the server to your wishes, where you '''must''' perform a signal-event post-upgrade; signal-event reboot for all changes to take effect.

=== SME V9 Configuration ===
 +
 +
Things have changed slightly for v9
 +
 +
Use the same db settings and templates as for v8.
 +
 +
You can make one small change to the template. Replace :
 +
 +
  my $gw = $ExternalInterface{'Gateway'};
 +
 +
With
 +
 +
  my $gw = $GatewayIP;
 +
 +
 +
To update the config files you now need to run :
 +
 +
/etc/e-smith/events/actions/update-ifcfg
 +
signal-event post-upgrade;signal-event reboot
 +
 +
Note that you will not see MAC addresses in the Internal Interface settings as you did in v8

{{Warning box|The procedures listed here are outside normal SME operation. They are not guaranteed to work. Make sure you fully understand what you are going before proceeding}}
 +
Example to create a SME Server 8.1-x86_64 VM :
 +
 +
1) you have to install OpenNode, it can be installed after a CentOS6 on cloud hosting : http://opennodecloud.com/downloads/
 +
 +
 +
2) Connect to your VE :
 +
 +
ssh -c blowfish -X -C root@YourServerIP
 +
 +
 +
3) Download SME Server ISO :
 +
 +
cd /storage/local/iso/
 +
wget http://mirror.smeserver.eu/smeserver/releases/8.1/iso/x86_64/smeserver-8.1-x86_64.iso
 +
 +
 +
4) Pre-create VM disk image :
 +
 +
qemu-img create -f qcow2 -o preallocation=metadata /storage/local/images/smeserver8vm.qcow2 10G
 +
 +
 +
5) Launch installation inside screen :
 +
 +
screen
 +
virt-install --connect qemu:///system \
 +
--name smeserver8vm --ram 1024 --vcpus 1 \
 +
--disk path=/storage/local/images/smeserver8vm.qcow2,format=qcow2,bus=virtio,cache=none \
 +
--network=bridge:vmbr0,model=virtio --vnc --os-type=linux --os-variant=rhel5 \
 +
--cdrom /storage/local/iso/smeserver-8.1-x86_64.iso --accelerate --noautoconsole --keymap=fr
 +
 +
 +
6) Detach screen :
 +
 +
[CTRL+A+D]
 +
 +
 +
7) launch virt-manager to manage your VM
 +
 +
virt-manager

 +
 +
Please see the forum post for instructions on v9
 +
 +

You will find help in the opennode's wiki and forum.
