IP addressing how it works

[Upendra Dhoble]

Hi,
my setup

we have multiple LAN cards eth0 eth1 and eth2 , and vmbr0

Question
Initially eth0 was on dhcp and now I need to give a static IP address from different network , ( like earlier 192.168.100.2 on dhcp and now 10.10.10.10
does I need to change anything like in host.conf to make it static ?

what could be the impact on vmbr0 and can I enable eth1 to act as a load balancer or aggregate the bandwidth so can run many VM's should not have any network usage impact or to reduce the load on single eth0

Thanks
Upendra
