Exposing libvirt networks to the LAN?

[gunnarniels]

Hello, hopefully someone can point me in the right direction because I'm not really sure what I need to even research to accomplish this...

I am on my laptop on a vanilla home network 192.168.1.0/24, I have a centos7 server at 192.168.1.2, and on that server, I'm running libvirt with a network 192.168.100.0/24. I'm simply looking for a way to be able to communicate with vms on the 192.168.100.0/24 network from my laptop, which knows nothing about that subnet. I added a route to my laptop with the centos server as the gateway, but I can't ping the guests on the 100 network. In my research, I've found tutorials that suggest I need to add some net/forwarding rules with ip tables on the centos server, but none of them have worked.

Could anyone point me in the right direction for this?

The usual way is to use a bridge on the host and use bridged networking instead of NAT.

Or if you don't want to make any changes on the network - you can use simple ssh "magic", if plain ssh is the goal.

Thanks Trevor. I'm not very familiar with this, do you have any recommended reading / tutorial on how to accomplish this?
