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 Ian jonhson wrote: -- Forwarded message -- From: Ian jonhson [EMAIL PROTECTED] Date: Oct 18, 2007 2:17 PM Subject: Re: [Users] boot error - unable to mount root fs on unknown-block(0, 0) To: [EMAIL PROTECTED] Thank you very much!

Re: Fwd: [Users] boot error - unable to mount root fs on unknown-block(0, 0)
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?

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

Re: Fwd: [Users] boot error - unable to mount root fs on unknown-block(0, 0)
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?

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. ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users

You probably configured your kernel incorrectly (missing initrd, device of filesystem drivers?). Try installing a pre-built kernel image instead, it's more likely to be bootable without problems. Where can I get the pre-built kernel image? After install the kernel-patch, the system compiled the kernel and created the optional item in /boot/grub/menu.lst. What I had done is under the instructions of openvz wiki. Is there something wrong? Thanks in advance.

The wiki page you referred gives info about how to configure this. After install the kernel-patch, the system compiled the kernel and created the optional item in /boot/grub/menu.lst. What I had done is under the instructions of openvz wiki. Is there something wrong? These instructions are OpenVZ-specific, i.e. they only recommend openvz-specific options in kernel config. Any other kernel config options (there are a lot of) are on your own. One simple example of what could be done wrong -- if you haven't enabled support for SATA disks, and your HDD is SATA you are in trouble. So, if you are not experienced in kernel recompilation, you'd be better of with precompiled kernel. Thanks in advance. Hope that helps, Kir.
