I just updated to Proxmox 4.2 and after reboot network is unreachable.

I can fix that manually by login via KVM console and executing:
brctl addbr vmbr0 eth3
ifup vmbr0
ifup vmbr0:1
ifup vmbr0:2
ifup vmbr0:3
ifup vmbr0:4


My /etc/network/interfaces:
auto lo
iface lo inet loopback

auto eth3
iface eth3 inet manual

iface eth0 inet manual

iface eth1 inet manual

iface eth2 inet manual

auto vmbr0
iface vmbr0 inet static
address 83.167.254.20
netmask 255.255.255.128
gateway 83.167.254.1
bridge_ports eth3
bridge_stp off
bridge_fd 0
pre-up iptables-restore < /etc/iptables.rules
post-up route add -net 192.168.1.0 netmask 255.255.255.0 gw 10.0.10.20 # VPN
post-up route add -net 10.1.0.0 netmask 255.255.0.0 gw 10.0.10.20 #VPN

auto vmbr1
iface vmbr1 inet static
address 10.0.0.1
netmask 255.255.0.0
bridge_ports none
bridge_stp off
bridge_fd 0


auto vmbr0:1
iface vmbr0:1 inet static
address 83.167.254.21
netmask 255.255.255.128

auto vmbr0:2
iface vmbr0:2 inet static
address 83.167.254.22
netmask 255.255.255.128

auto vmbr0:3
iface vmbr0:3 inet static
address 83.167.254.23
netmask 255.255.255.128

auto vmbr0:4
iface vmbr0:4 inet static
address 83.167.254.24
netmask 255.255.255.128


Only relevant information in logs are:
