TWIMC: it appears that OpenVZ patch breaks 802.1q VLAN support at
least for 2.6.24 kernel. Checked on both i386 and x86-64 platforms
connected to my old good Cisco Catalyst 2950 - while vanilla 2.6.24
kernel works just fine, rebuilding it with OpenVZ patch causes it
to discard network packets like if they were destined to unknown
I was unable to check this on stable OpenVZ version, as kernel
2.6.18 does not support my hardware, but problem should persist
there as well.
Temporary(?) solution: if you don't use the CONFIG_VE_ETHDEV aka
"virtual ethernet device" (and you normally don't) you can revert
the OpenVZ patch for net/8021q/* files in the kernel source tree
to get working kernel. PLEASE NOTE: this solution is NOT CHECKED
thoroughly and should be used only as a TEMPORARY measure to get
your server working here and now.
For people who are not experienced kernel hackers I made two files:
(should be applied to kernel source tree after OpenVZ patch) and
(the complete kernel source). Once again: they are EXPERIMENTAL.
