Re: Qemu: network connection host => guest
Hi,
Yes. It is possible to have a network connection between the host and
the virtual (QEMU) machine. The way you setup the connection depends on
your host OS: Window$ or Linux. If you search the web for a while
you'll find some suggestions for both OS. If you can't make it work,
let me know, and I'll try to prepare a small HOWTO for you (for a Linux
based host, I don't use Win#@$).
Once you get a valid network connection between the host and the virtual
machine, you may use SSH to redirect connections on the host to the
virtual machine with:
ssh VMIP -L LP:localhost:RP
where
VMIP = virtual machine IP
LP = local port (on the host)
RP = remore port (on the virtual machine)
For example, assuming your virtual machine (VM) has ip 172.20.0.2 and
that you want to redirect your http port (80) to the VM 8080 port you
should execute
ssh 172.20.0.2 -L 80:localhost:8080
>From now on, any connection to HOST:80 will be forwarded to VM:8080
Hope this helps,
João
