| 1 | This directory contains the implementation of vnets: |
|---|
| 2 | virtual private networks for virtual machines. |
|---|
| 3 | |
|---|
| 4 | make |
|---|
| 5 | - compile in local dirs. The module is in vnet-module/vnet_module.ko. |
|---|
| 6 | |
|---|
| 7 | make dist |
|---|
| 8 | - compile and install into $(XEN_ROOT)/dist/install, |
|---|
| 9 | - where XEN_ROOT is the root of the xen tree. |
|---|
| 10 | |
|---|
| 11 | make install |
|---|
| 12 | - compile and install into system. |
|---|
| 13 | |
|---|
| 14 | By default the makefiles expect this code to have been installed |
|---|
| 15 | in tools/vnet in a xen source tree. If compiling outside the xen |
|---|
| 16 | source tree, set XEN_ROOT to the location of the xen source. |
|---|
| 17 | You can do this in the environment or in a Make.local file |
|---|
| 18 | in the current directory (see Make.env for details). |
|---|
| 19 | |
|---|
| 20 | The xen0 kernel must have been compiled before building the vnet module. |
|---|
| 21 | The vnet module installs to |
|---|
| 22 | /lib/modules/<kernel version>-xen0/kernel/xen/vnet_module.ko |
|---|
| 23 | |
|---|
| 24 | The vnet module should be loaded before starting xend, or |
|---|
| 25 | xend will fail to create any persistent vnets it has in its configuration. |
|---|
| 26 | The script network-vnet is a modified version of the xen network script |
|---|
| 27 | that loads the module if it's not already loaded. |
|---|
| 28 | |
|---|
| 29 | The module uses kernel crypto functions, and these need to be |
|---|
| 30 | enabled in the xen0 kernel config. They should be on by default - |
|---|
| 31 | if they're not you will get compile or insmod errors (see below). |
|---|
| 32 | |
|---|
| 33 | Kernel config options: |
|---|
| 34 | |
|---|
| 35 | 1) You will need to have your xen0 kernel compiled with HMAC_SUPPORT |
|---|
| 36 | 2.6.x = (MAIN MENU: Cryptographic Options -> HMAC Support) |
|---|
| 37 | BEFORE running "make install". |
|---|
| 38 | |
|---|
| 39 | 2) You will want at least some of the other algorithms listed under |
|---|
| 40 | "Cryptographic Options" for the kernel compiled as modules. |
|---|
| 41 | |
|---|
| 42 | 3) You will want the networking IPsec/VLAN options compiled in as modules |
|---|
| 43 | 2.6.x = (MAIN MENU: Device Drivers -> Networking Support -> |
|---|
| 44 | Networking Options -> |
|---|
| 45 | IP: AH transformation |
|---|
| 46 | IP: ESP transformation |
|---|
| 47 | IP: IPComp transformation |
|---|
| 48 | IP: tunnel transformation |
|---|
| 49 | |
|---|
| 50 | IPsec user configuration interface |
|---|
| 51 | |
|---|
| 52 | 802.1Q VLAN Support |

| 54 | Please refer to the additional documentation found in tools/vnet/doc for |
|---|
| 55 | proper syntax and config file parameters. |
