Thank you very much!

I have created my own VE, however how can I login VE by ssh? I used
the IP setting described in
http://wiki.openvz.org/Installation_on_Debian.

Thanks again,

Ian

Ian,

just like to any other usual machine using
ssh from your workstation.

1. assign IP address to some VE using
ve0# vzctl set <VEID> --ipadd <VEIP> --save

2. just in case, check that VE is pingable from your workstation:
ws# ping <VEIP>

3. just in case, check that VE is running sshd service:
ve0# vzctl exec <VEID> ps axf | grep sshd

if it is not running sshd then enter to VE using vzctl enter command
and install/start sshd service.

4. don't forget to set root user password
ve0: vzctl set <VEID> --userpasswd root:mypassword

5. now you can login to VE as to usual machine using it's IP

Kirill

Thank you very much~~

But it seems that I can not connect internet in VE. It is OK when ping
to its host system, however when ping external IP address, it dumps. I
google the internet to find how to set the netwrok in VE, but I can
not find any hint to do it.

Could anybody give some advices how to configure network?

Thanks again,

Ian

Have you enabled IP forwarding (as per 
http://wiki.openvz.org/Quick_installation#sysctl)? Are you using real IP 
for your VE?

Or, in case of Debian which you use, more relevant howto is

In where I should enable the IP forwarding, host system or VE (Sysem
image file)?
I enabled the IP forwarding in /etc/sysctl.conf in host system (by
copying configuration directly from
http://wiki.openvz.org/Quick_installation#sysctl), but it isn't work;
it is same when enabled in VE.

I used the real IP. For example, host IP address is 192.168.8.54, and
I set the IP of VE is
192.168.8.55. Both are effective IP addresses.

Then, I started VE.

Under above setting, I entered VE and run  apt-get update. However, I
got error message.
No matter what IPs I pinged, all can not make connection.


What should I do next? Could anybody give me some advices?

Thanks,

Ian

Hi,

I guess maybe some configuration in VE is wrong. So I reseted my VE
network as follows.
If there are something wrong, please correct me. Thank you very much.

I booted my system and selected the openvz environment, then

# cat /etc/network/interfaces
...
The primary network interface
allow-hotplug eth0
iface eth0 inet static
    address 192.168.8.54
    netmask 255.255.255.0
    network 10.61.0.0
    broadcast 10.61.0.255
    gateway 192.168.8.1
    dns-nameservers 10.61.0.254
    dns-search anqin-test-debian4
auto eth0

Before I started VE, I set the network by vzctl command,

# vzctl set 777 --ipadd 192.168.8.60 --nameserver 10.61.0.254
--hostname anqin-test-debian4  --save

OK, then I started VE:

# vzctl start 777
# vactl enter 777
# ping 192.168.8.1

The ping command said it can not connect to gateway:192.168.8.1. However,

# ping 192.168.8.54

is OK, VE can connect to VPS.

What is wrong with my setting?
