I upgraded the kernel to the latest version and after reboot the containers are not pinging.

I checked /etc/vz/vz.conf
and
NEIGHBOUR_DEVS=all

There are different subnets so I even created route-etho

/etc/sysconfig/network-scripts named
"route-eth0" with content

Subnet.0/24 dev eth0
Subnet.0/24 dev eth0

And restarted the vz services and network services.

Still IP's are not pinging.

Thanks

I have been facing some what similar issue but its intermittent in our case http://forum.openvz.org/index.php?t=msg&th=8445&star t=0&SQ=8cf899b9f819e765c6831fbb246c9d31&

What is the output for below commands :

arp -n

route -n

Also what are the details of the hardware you are using ?
