 Posted: Sat Jul 02, 2005 9:00 pm Post subject: vserver network problems [SOLVED] |
 |
|
I'm just installed vserver, and I think I've got a virtual server running. However, I can't connect to it over the network. A network interface exists for it, but connecting to it instead connects to the host server.
Why do I think it's running?
I can do:
| Code: |
thor root # vserver gentoo start
thor root # vserver gentoo status
Vserver 'gentoo' is running at context '1030'
Number of processes: 1
Uptime: 00:00
thor root # vserver gentoo enter
gentoo / # ps -ef
UID PID PPID C STIME TTY TIME CMD
root 1 0 0 21:44 ? 00:00:00 init [3]
root 2774 8884 0 21:44 pts/0 00:00:00 /bin/bash -login
root 2794 2774 0 21:45 pts/0 00:00:00 ps -ef
gentoo / # ifconfig -a

I'd expect to see syslog-ng running in the ps list, but it isn't. If I try to start it manually, I get lots of errors:
| Code: |
gentoo / # /etc/init.d/syslog-ng start
* ERROR: system is missing /sbin/depmod !
* ERROR: Problem starting needed services.
* "checkfs" was not started.
* ERROR: Problem starting needed services.
* "localmount" was not started.
* ERROR: Problem starting needed services.
* "clock" was not started.
* ERROR: Problem starting needed services.
* "syslog-ng" was not started.

depmod seems to be provided by modutils and module-init-tools, neither of which are installed. Should they be? Is this the real problem, or just a symptom of something else that has gone wrong?
The virtual server should have ipaddress 192.168.161.30, just as above, and that network is brought up and down correctly when I start and stop the vserver. However, if I try to connect to it, I get connected to the main host rather than the virtual host.
Finally, when I shutdown the vserver, I get an error:
| Code: |
gentoo / # logout
thor root # vserver gentoo stop
vkill: vc_ctx_kill(): No such process
Vserver '/etc/vservers/gentoo' still running unexpectedly; please investigate it manually...
thor root #
|
I can't find any log files for the virtual host, so I don't even know how to check for error messages and the like. In the above examples, 'gentoo' is the virtual host and 'thor' is the main server (a single processor x86 box).
FWIW, I followed the instructions at http://www.gentoo.org/doc/en/vserver-howto.xml in order to install things.
Any help greatly appreciated... |

|
|
Apparently the Gentoo installation docs have changed since the Gentoo vserver HOWTO was written. Section 6e, "Upgrading Baselayout", should be ignored for the vserver guest install. Following these instructions breaks the world since the vserver baselayout is already part of the stage tarball.
Figured that out after an IRC chat with Hollow. |

Use "ps aux" to view all processes instead.
