port forward on the fly or at startup with virt machine manager and kvm-qemu

[michael12345]

I'm running some vm's in FC12 with kvm-qemu and using virt machine manager. I'd like to have some ports automatically forward on startup and be able to add redirections on the fly.

Redirection on the fly is talked about here, but I am getting lost on what should be basic instructions. http://www.linux-kvm.com/content/hos...edirection-fly

As far as startup, In the past I just ran qemu from the cli and manually specified redirection with redir. I can't figure out how to do it with The virt machine manager which I am using to start my VM's now. I do not want the guests to see the host. Any help is appreciated.

From cli startup without virt machine manager, it looked like this: qemu -m 256 -hda vm.img -redir tcp:5555::80 -redir tcp:5556::445 &

You'll have to create/edit the XML configuration for the appropriate guest. There you can apply rules according to http://libvirt.org/formatdomain.html#elementCharChannel and/or http://libvirt.org/formatdomain.html#elementsCharTCP

I'm not sure how you want to access the VMs externally, but SSH's -R switch (and -L switch too) is very nice if you want to setup some quick port mapping while doing remote access.
