11 years ago Hi Vasilica,
Quick question, are you using the appliance to get a multi node environment working?,
Anyway, first requirement to get an environment with multinode is an isolate network for this. Take a look on to the 5.3 section in the admin manual to the networking diagram. (http://theqvd.com/support/documentation/the-qvd-administration-manual#_networking_requirements.) Basically is a requirement to get the the hosts, and the virtual machines stays at the same subnet on order to get the L7R working properly.
So you must have the hosts interfaces and the Virtual Machine interfaces in the same subnet. Therefore your /etc/networks/interfaces should be something similar to this.
This file describes the network interfaces available on your system
and how to activate them. For more information, see interfaces(5).
The loopback network interface
auto lo iface lo inet loopback
Bridge for eth0
auto qvdnet0 address 192.168.1.x --> Node Ip netmask 255.255.255.0 network 192.168.1.0 gateway 192.168.1.1 pre-up ip link set eth0 down pre-up brctl addbr br0 pre-up brctl addif br0 eth0 pre-up ip addr flush dev eth0 post-down ip link set eth0 down post-down ip link set br0 down post-down brctl delif br0 eth0 post-down brctl delbr br0
You must to reserve the lower numbers in the subnet for the nodes, so get the vm.network.ip.start=192.168.1.11 and the 10 first will be reserved for the Nodes. And also, you should keep the gateway in this range to avoid possible conflicts.
Regards.

Hello everyone,
I am tying to add one more node to config but cannot start a vm on the node that I have just added

environment
Virtual appliance provided by qindel
add a new VM with Ubuntu 12.04 and installed a new node... with :
apt-get install perl-qvd-node installed and configured dnsmasq with:
apt-get install dnsmasq service dnsmasq stop sed -i s/ENABLED=1/ENABLED=0/ /etc/default/dnsmasq
added to /etc/sysctl.conf net.ipv4.ip_forward=1
I had copied /etc/qvd/* from the VM appliance provided by qindel
my /etc/network/interfaces

Added the new node on admin console and it show its status as "running"
I could use some help here... thank you Greetings, Vasilica Petcu
P.S. if you need more info... tell me :)
