The solution is echo 2.6.9 > /proc/sys/kernel/virt_osrelease



[root@spv507 ~]# vzctl start 1000
Starting VPS ...
VPS is mounted
Adding IP address(es): xxx.xxx.xxx.xxx
FATAL: kernel too old
Setting CPU units: 100000
FATAL: kernel too old
File resolv.conf was modified
VPS start in progress...
FATAL: kernel too old

[root@spv507 ~]# uname -r
2.6.8-022stab072.2-enterprise

Any ideas on that one?

1. you can try setting
/proc/sys/kernel/virt_os_release
to 2.6.16 Smile))

2. I asked Kir to check it. Looks like FC5 requires 2.6.15 or later.

To fix the problem with FC5 start, you need to do
echo 2.6.9 > /proc/sys/kernel/virt_osrelease


After that, everything works fine. You can add this line to your startup scripts if you need this after reboot.

The problem is caused by the fact FC5 was compiled with the minimum kernel requirement of 2.6.9. But it works fine with 2.6.8 as well Smile

Thanks! I'll give it a shot. I assume this will have no affect on any other VPS running on the system, such as the CentOS, Debian and etc?

Is there any remote chance that this is related to this error (linked)?

Aside from the fact they will be thinking they are running on 2.6.9 not 2.6.8 -- no. I believe this should not create any problems at all.

What kernel version are you using? Can you post the output of uname -a here?
