I have just upgraded from 2.6.24-openvz-006.5 to openvz-sources-2.6.27.2.1-r2, and the sit module (ipv6-in-ipv4 tunnel driver) stopped to work in the VE. Works fine on the HN. Its built into the kernel, not loaded as module. vps ~ # uname -a Linux login5 2.6.27-openvz-briullov.1-r2 #1 SMP Wed Aug 5 22:45:55 CEST 2009 x86_64 Intel(R) Pentium(R) Dual CPU E2200 @ 2.20GHz GenuineIntel GNU/Linux Reproducible: Always Steps to Reproduce:

Could you try to build kernel with CONFIG_SYSFS_DEPRECATED_V2 option? According to upstream http://bugzilla.openvz.org/show_bug.cgi?id=1253 it should fix this problem. Does it?
Its already on. hn linux-2.6.27-openvz-briullov.1-r2 # grep SYSFS .config CONFIG_SYSFS_DEPRECATED=y CONFIG_SYSFS_DEPRECATED_V2=y CONFIG_ACPI_SYSFS_POWER=y CONFIG_SYSFS=y
Well. Then could you give a more details what do you mean by "stopped working"?
vps ~ # ip tunnel add v6link mode sit remote 192.168.0.1 ioctl: No such device vps ~ # ip tunnel gre0: gre/ip remote any local any ttl inherit nopmtudisc vps ~ # host ~ # ip tunnel sit0: ipv6/ip remote any local any ttl 64 nopmtudisc gre0: gre/ip remote any local any ttl inherit nopmtudisc
BTW, what happens if you revert the following patch: http://git.openvz.org/?p=linux-2.6.26-openvz;a=commit;h=bd5e8068db8448a24b87f096622a5f4dac93b31a ? I guess it's just disabled and there is no way to enable it.
After reading the bugreport you linked to, I found that vzctl 3.0.23 or later is required to enable sit in VE's. vzctl set 101 --features sit:on --save Works now :)
Great! I'm not using this feature but I'm happy it works for you. )
