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 VLAN number. 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: ftp://home.gremlin.ru/pub/linux/Owl/patches/ovz-2.6.24-vlan.diff (should be applied to kernel source tree after OpenVZ patch) and ftp://home.gremlin.ru/pub/linux/Owl/kernel/linux-2.6.24-ovz.tar.gz (the complete kernel source). Once again: they are EXPERIMENTAL. -- Alexey V.
