Can we run guest o.s. on KVM without enabling NAT and iptables?
The reason to do this is , I wanted to disable conntrack module from my system and to disable that I must have to delete iptable and NAT.
I am getting the following message, when I start guest o.s. on KVM (iptable and NAT disabled):
Error starting domain: internal error 'Network default' is not active.
Is their any way to run guest o.s. with NAT disabled? or Is their any way to disable conntrack module and still can use KVM to run guest OS ?
I am using Ubuntu 10.04
You can remove the default virsh network like sudo virsh net-destroy default sudo virsh net-undefine default The most common networking setup that doesn't use NAT + iptables is probably bridged networking: http://wiki.libvirt.org/page/Networking#Bridged_networking_.28aka_.22shared_... - Cole
