I've successfully started 129 domains, but it was some time ago and its not totally inconceivable that things could have rotted.
You're not simply running out of memory are you? I'm afraid the error codes on failure aren't very helpful -- its something that we'd certainly like to fix.
The machine has 2GB of memory, how much memory did 129 guests require?
According to my notes, I was using a machine with 2GB of RAM, and started domain 0 with 48000KB and all the other domains with 15000KB. There was probably enough spare RAM to start a few more, but I'd only created 129 root file systems, so didn't try.
Xen currently reserves quite a bit of RAM for itself, rather more than is strictly needs for most configurations, but it hasn't been a priority to fix it.
