Description Dietmar Maurer 2008-11-24 08:23:21 EST
The update indroduced a bug:


seems that:

  ip addr add 0 dev "$host_ifname"

does not create the interface. Instead the old way

 ifconfig "$host_ifname" 0

vzctl creates this device via veth_ctl() function,
so why should vznetaddbr bother?
Comment 2 Dietmar Maurer 2008-11-25 02:50:45 EST
It does not work here (debian etch) - dont know why. 

Anyways, why did you change it - the previous version also use 'ifconfig'?

> debian etch

used packages:

vzctl (3.0.11-14), Mon, 10 Mar 2008 18:58:04 +0100
iproute (20061002-3), Thu, 14 Dec 2006 20:11:55 +0100

and the OpenVZ kernel is the pve 2.6.24-1 (ovz005) ?
Comment 6 Dietmar Maurer 2009-01-23 02:30:24 EST
I am on Proxmox VE - latest ubuntu kernel and latest vzctl from git.

Anyways, I cant reproduce the error anymore - it works both ways.

But with the new way the interface shows up in " /proc/net/dev", but
not in the output by "ifconfig"? Whats the difference?
Comment 7 Dietmar Maurer 2009-01-26 04:48:39 EST
OK, it does not work a plain Proxmox VE installation:

vzctl 3.0.23
iproute 20061002-3

But it works when I install shorewall - maybe it is dependend in the modules loaded. I will do more tests here.
Comment 8 Dietmar Maurer 2009-01-26 05:13:38 EST
Unfortunately I am unable to see why it works/sometimes. The only consistent difference I see is that the interface shows up in " /proc/net/dev", but
not in the output by "ifconfig".

Comment 10 Kir Kolyshkin 2009-04-17 12:15:12 EDT

fixed in git, will appear in vzctl >= 3.0.24.

Bug was fixed more than one year ago and there were no complains from reporter after fix. We believe bug fix helped and mark bug as closed.
