Networking issue : container won't start after last update

[romainrbr]

Hello,

After updating Proxmox to 4.0-16, none of my containers won't start, throwing the following error :

Undefined subroutine &PVE::Network::is_ip_in_cidr called at /usr/share/perl5/PVE/LXC/Setup/Debian.pm

Here is the network configuration that was previously working :



And here is the bridge configuration :




I fixed the issue by editing commenting the following lines in /usr/share/perl5/PVE/LXC/Setup/Debian.pm

if (defined($cidr) && !PVE::Network::is_ip_in_cidr($d->{gw}, $cidr, 4)) {
# gateway is not reachable, need an extra route
$net->{needsroute} = 1;
}

Can anyone confirm that this is indeed a bug ?

No this should not be a bug, but rather a bit off an outdated version, you need to have the libpve-common package in version 4.0-34 version or newer as they implement the PVE::Network::is_ip_in_cidr methods.
Proxmox VE 4.0-22 is also the newest stable version.

Did you upgrade to the newest PVE4.0 by
# apt-get update
# apt-get dist-upgrade

Hello Thomas,

Applying a dist-upgrade indeed fixes the issue.
Thank for your help.
