[Pkg-vsquare-devel] Bug#568363: Timing issue in /etc/network/if-pre-up.d/vde2

[Maik Zumstrull]

Package: vde2
Version: 2.2.2-3
Severity: normal

On this system, I noticed that a vde interface fails to come
up at boot, but ifup/ifdown by hand works when the system
is running.

I found that this is a timing issue. ifup starts the switch
process, then fires off an ifconfig, but occasionally the tap
interface has not been created yet at that point and ifconfig
fails. Afterwards, the tap is created, so you end up with
a switch process running and an unconfigured interface.

On my system, I choose the dirty fix of putting a "sleep 2"
after start-stop-daemon in the vde2 script. The clean solution
would be to have vde_switch not background itself until the
tap interface exists.
