I'm new to openVZ and I'm trying it out following the howto's on: http://wiki.openvz.org/Installation_on_Debian and http://wiki.openvz.org/Debian_template_creation
First time I started the VE, I get:
~ # vzctl start 777
Starting VPS ...
VPS is mounted
Adding IP address(es): 192.168.1.28
Unable to add IP 192.168.1.28: Inappropriate ioctl for device
Unable to del IP 192.168.1.28: Inappropriate ioctl for device
VPS start failed
Stopping VPS ...
VPS was stopped
VPS is unmounted
Ok, got that fixed, some module was missing:
~ # lsmod|grep vz
vzethdev 10152 0
vzmon 40328 1 vzethdev
ipv6 235456 15 vzmon
~ # modprobe vznetdev
~ # lsmod|grep vz
vznetdev 16384 0
vzethdev 10152 0
vzmon 40328 2 vznetdev,vzethdev
ipv6 235456 15 vzmon
Second try:
~ # vzctl start 777
Starting VPS ...
VPS is mounted
Adding IP address(es): 192.168.1.28
RTNETLINK answers: No such device
vps-net_add ERROR: Unable to add route /sbin/ip route add 192.168.1.28 dev venet0 src 192.168.1.27
VPS start failed
Stopping VPS ...
VPS was stopped
VPS is unmounted
Ok, another module is still missing, but I can't load it:
~ # modprobe vzdev
FATAL: Module vzdev not found.
The module simply isn't there:
~ # ls -la /lib/modules/2.6.18-2-openvz/kernel/kernel/ve/
total 68
drwxr-xr-x 2 root root 4096 2007-05-27 14:19 .
drwxr-xr-x 4 root root 4096 2007-05-27 14:19 ..
-rw-r--r-- 1 root root 48783 2007-05-27 14:16 vzmon.ko
-rw-r--r-- 1 root root 10133 2007-05-27 14:16 vzwdog.ko
Weird enough, I cannot select "CONFIG_VZ_DEV" via 'make menuconfig'. I adjusted it to "m" in the .config file, but this was ignored:
~ # grep -i vz /boot/config-2.6.18-2-openvz
# Linux kernel version: 2.6.18-2-openvz
CONFIG_VZ_QUOTA=y
CONFIG_VZ_QUOTA_UGID=y
# OpenVZ
CONFIG_VZ_GENCALLS=y
CONFIG_VZ_DEV=y
CONFIG_VZ_WDOG=m
CONFIG_VZ_CHECKPOINT=m
Anyone got a clue? I'm using Debian Etch's linux-sources and pathes.

Ahem... Why do you load modules by hand? Run `/etc/init.d/vz start` command. It'll load all necessary modules and produce necessary tuning.
HTH,
Vasily.

Sorry, forgot to write about that. It (also) doesn't work:
~ # /etc/init.d/vz start
Starting OpenVZ: ..failed
~ # tail /var/log/vzctl.log

I think the problem lies somewhere at the kernel patching/configuration/compilation. For some reasson it is not possible to set:
It keeps getting:
Even when I change it with an editor to "m".

Using 'make menuconfig' I don't have the option to set te VE device to module:
| | [*] Virtual Environment support (NEW) | |
| | <M> VE calls interface (NEW) | |
| | <M> VE network device (NEW) | |
| | <M> Virtual ethernet device (NEW) | |
| | --- VE device | |
| | [*] VE netfiltering (NEW) | |
| | <M> VE watchdog module (NEW) | |
| | <M> Checkpointing & restoring Virtual Environments (NEW) | |
Help about "VE device" says:
| CONFIG_VZ_DEV: |
| |
| This option adds support of vzdev device, which is used by |
| user-space applications to control Virtual Environments. |
| |
| Symbol: VZ_DEV [=y] |
| Prompt: VE device |
| Defined at kernel/Kconfig.openvz:48 |
| Location: |
| -> OpenVZ |
| Selected by: VZ_QUOTA && QUOTA || VE_CALLS && VE || VE_NETDEV && VE_CALLS && NET || VE_ETHDEV && VE_CALLS && NET |
If I understand correctly "VZ_DEV" can't be made a module...

Hmmzz .. So he sets "CONFIG_VZ_QUOTA" to be a module instead of including it in the kernel. After that, the VZ device *is* available for module selection.
|
Since I'm waiting for my kernel to compile, I can explain why I was somewhat staggered seeing that a working config had "CONFIG_VZ_QUOTA=m". The Howto I followed up ( http://wiki.openvz.org/Installation_on_Debian#or_build_your_ own_kernel-image_.28debian_way.29) said CONFIG_VZ_QUOTA should be included in the kernel .. is this a fault in the howto?
Hope to find out soon

Guess I should update the wiki
