Hi all,

I have a virtual machine and from the hypervisor I can ssh to it by its vip, which is 192.168.122.193. Now I am wondering in any machine how can I ssh to it, or make a connection with socket? should I make a bridge? how?

Thanks in advance.

I think bridge is required ..

I am not sure how can I create the bridge, can someone help me, whenever I wanted to make the bridge, the network become completely disabled.

Also does NAT also works? How it is different from bridging, which one is easier to setup?

which hypervisor your having ? and you need to connect guest to lan right ?

I have KVM. Yes

I use qemu/kvm with bridge and works fine.

How i did it:

1. created a br0 interface that has eth0 as member
2. transferred the eth0 network config to br0, leaving eth0 with no IP address
3. added br0 as shared device to the VMs via virt-manager (add/modify network adapter, select "Specify shared device name", type the name of your bridge device).
So every VM on startup will automatically create a vnetX interface that will be a member of br0. They behave as separate network devices and can communicate just as separate computers both between them and the host and the rest of the network (note that firewalls in effect on br0 can block ports on its members so configure accordingly). Also ifconfig will not show their network address on the host machine.

Note that i use virt-manager where this kind of setup is trivial to do. This kind of setup gives the most network reachability, as other options such as using macvtap will prevent the host from reaching the VMs via their IPs, although the VMs can be reached from other computers.
