[Qemu-devel] [PATCH] net/tap: Add qemu_name to ifup/ifdown callback script parameters

[Anton Worshevsky]

Add additional parameter to network configuration callback script calls
in launch_script(). External script can provide any exotic network
configuration for VM instance based on qemu_name as new param.

It's convenient to have only one ifup script without tricks with symlinks to it
for each VM instance on large VDS hosts.
