<snip> Maybe you'll have to compile a new kernel. There's an options(4) option called tun. I had to add something like pseudo-device tun 16 on a kernel config file once. If I remember correctly, the default is the kernel to allocate 4 tun channels. That would explain why it's failing in the 5th QEMU guest. Don't forget that customized kernels aren't "supported".
