Verify with: ls /lib/tls if that exists, then also Java is using them for threading and it won't work well. Very recent UML releases (2.6.15-bs3 from my homepage) support TLS well.

[uml-user] Multiple UMLs sharing a single tap device
Hi, I was wondering if it was possible to have multiple UMLs share a single tap device. My goal is to have one subnet on tap0 in which all the UMLs are too, so you get one big virtual ethernet network. I now get 'TUNSETIFF failed, errno = 16' when I try to get the second UML to work though. What am I doing wrong here? What is the recommended way to build a virtual network using UMLs?

I doubt it's possible, since each UML needs its own IP address and a shared interface wouldn't know which guest to send packets to. The tunnel driver can spawn arbitrarily many tun/tap devices at little cost; if you can create one, you can create ... I actually don't know the upper bound, but it must be at least 16 and it might even be a module parameter if you need to raise the limit. The host (configured as a router) will do the virtual Ethernet thing as its default behavior. With many guests on one host, remember that the CPU is shared, and if several guests get CPU-intensive at the same time their individual performance will drop off. Also UMLs take a lot of memory; be sure there's enough. James F.

It was -bs3 or -bs1? -bs1 gave a lot of messages, but -bs3 not, and until now all report say "-bs3 is ok".

That's possible, but you need to make UML use the daemon transport, and run uml_switch beforehand, connecting it to a pre-setup tap0 device.

You can also give each uml its own tap device, then use standard linux bridging to bridge all the taps together on the host. Though I wonder if this method has advantages or disadvantages compared to using the switch daemon. I prefer using "normal" networking as opposed to a special daemon. But maybe it's less efficient or something. Jason --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
