Numerous how-tos all over the Internet show how one would set up a tunnel using ssh, e.g.: ssh -f -o Tunnel=ethernet <server_ip> true I was wondering if there's a way to subsequently acquire the names of the local and remote tun/tap interfaces (e.g., using the default "-w any:any") for subsequent automatic tunnel configuration, e.g.: ip link set $TapDev up ip link set

Hi!! I found your ipconfig stuff in the udev rpm in SuSE 9.1. I'm about to setup a initramfs (pretty cool - much better than initrd) to boot linux diskless clients over the net. All the tools I would need, seem to be there with ipconfig/nfsmount ... I like to use the information I get from PXE/syslinux or Etherboot writing something like:

As multi-queue nics were commonly used for high-end servers, current single queue based tap can not satisfy the requirement of scaling guest network performance as the numbers of vcpus increase. So the following series implements multiple queue support in tun/tap. In order to take advantages of this, a multi-queue capable driver and qemu were also needed. I just rebase the latest version of
