Hi all,
First of all, I apologyze for my poor english 
I am a total newbie and I am desperated.
I've installed openVZ in a centOS 5.6, I can work with containers but i can't resolve any internet address within containers.
I just can ping, but when I make a wget, I always receive a wget: unable to resolve host address "google.com" message.
I've read lots of forums and messages, but I've found no solution. I'm not an expert in linux, nor networks.
I create the containers as follows:
- vzctl create 101 --ostemplate fedora-14-x86_64
- vzctl set 101 --ipadd 192.168.1.101
- vzctl set 101 --nameserver 62.14.4.64 --nameserver 62.14.4.65
My /etc/sysctl.conf file:
# Kernel sysctl configuration file for Red Hat Linux
#
# For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and
# sysctl.conf(5) for more details.
# Controls IP packet forwarding
net.ipv4.ip_forward = 1
net.ipv4.conf.default.forwarding = 1
net.ipv4.conf.all.forwarding = 1
net.ipv4.conf.default.proxy_arp = 0
# Controls source route verification
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.all.rp_filter = 1
# Do not accept source routing
net.ipv4.conf.default.accept_source_route = 0
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0
# Controls the System Request debugging functionality of the kernel
kernel.sysrq = 1
# Controls whether core dumps will append the PID to the core filename
# Useful for debugging multi-threaded applications
kernel.core_uses_pid = 1
# Controls the use of TCP syncookies
net.ipv4.tcp_syncookies = 1
# Controls the maximum size of a message, in bytes
kernel.msgmnb = 65536
# Controls the default maxmimum size of a mesage queue
kernel.msgmax = 65536
# Controls the maximum shared segment size, in bytes
kernel.shmmax = 68719476736
# Controls the maximum number of shared memory segments, in pages
kernel.shmall = 4294967296
My /etc/resolv.conf file:
nameserver 62.14.4.64
nameserver 62.14.4.65

Please can anyone help me? I don't know what can I do, I'm testing and changing without direction.
Thanks for your interest!
Added:
I tested:
ifconfig venet0 192.168.1.102 netmask 255.255.255.0 broadcast 192.168.1.255
Only for the first time... never more!
