Virtuozzo Virtualization SDK C API Reference
Allows to manually set IP addresses/Subnet masks to a network adapter in a virtual machine.
Note: For these changes to take effect, Virtuozzo Tools must be installed in the target virtual machine, and its network adapter settings should be configured to change automatically.
If the changes are applied to a stopped virtual machine, they will take effect the next time the machine is started. If the changes are applied to a running virtual machine, they will take effect on configuration changes commit.
