Is it possible to connect two qemu instances with each other via TCP
or socket and have both connected with the host network using only
user networking (SLIRP)?
Basically like
http://wiki.qemu.org/Documentation/Networking#User_Networking_.28SLIRP.29
but with a second qemu VM:
+-----------------+ +-----------------+
| qemu Process 1 | | qemu Process 2 |
| +---------+ | | +---------+ |
| | | | | | | |
| | Guest 1 | | | | Guest 2 | |
| | | | | | | |
| +----+----+ | | +----+----+ |
| | | | | |
| | | | | |
| =+====+===+========TCP/==========+ |
| | | | Socket | |
| | DNS | +-----------------+
| | |
+--|--------------+
|
Host network
I am able to do this with a third qemu VM which acts as a router for
the two VMs and I can get two qemu VMs to talk to each other but I
cannot get the one VM to use the built-in gateway and DNS of the
second one.
I know that there are ways other than SLIRP which can achieve this
but I want to be able to set this up without root access and I don't
care about performance since this setup is just for testing
purposes. Right now I'm just wondering if I can simplify my setup
leaving out the third router vm and just use the gateway/dns/routing
that qemu has already built in.
