Support for multiple NICs with configured addresses

[gtz42]

Make sure to follow and check these boxes before submitting an issue! Thank you.

• Supply print(libioc.VERSION)
• Supply the commands used, along with any steps to recreate it.
• Provide the output from the command you issued.
• Supply what you expected the result or output to be
• Checked that the problem has not already been fixed on master if using
  a stable release.

This is already supported.

>>> import libioc
>>> jail = libioc.Jail("myjail")
>>> jail.config["ip4_addr"] = "vnet0|192.168.23.2/24,vnet1|192.168.42.2/24"
>>> jail.config["ip4_addr"]
{'vnet0': AddressSet({IPv4Interface('192.168.23.2/24')}), 'vnet1': AddressSet({IPv4Interface('192.168.42.2/24')})}
>>> jail.save()

You can have multiple IP addresses on each interface as well as DHCP (or rtadv for IPv6).

Please keep in mind that you also need to configure your vnet interfaces before starting the jail:

>>> jail.config["interfaces"] = "vnet0:bridge0,vnet1:bridge1"
>>> jail.config["interfaces"]
{'vnet0': <libioc.BridgeInterface.BridgeInterface object at 0x8025230f0>, 'vnet1': <libioc.BridgeInterface.BridgeInterface object at 0x802523128>}

This should go directly into the handbook.
And probably can, verbatim.

Intended to add more information, as the described process does not work: (using the ioc command line tool):

root@mgr01:~ # ioc list

While vnet0 has an IP, vnet1 does not.

Let's update to the git version of libioc from the weekend (#d83a24bb56012d69bfe3ff3a8ac647d899540e23)

Successfully installed libioc-0.5.0

Using the Python interface the config is correct:

>>> import libioc
>>> jail = libioc.Jail("bastion")
>>> jail.config["ip4_addr"]
{'vnet0': AddressSet({IPv4Interface('192.168.11.249/24')}), 'vlan1': AddressSet({IPv4Interface('192.168.100.2/24')})}

But it's still not configured.

[gronke]

@gtz42 could you please post the output of the following command:

ioc get all bastion

The second device in your ip4_configuration is named vlan1, although the ifconfig output contains vnet1, so I would be particularly interested in the interfaces configuration.

[gtz42]

Thanks for spotting my typo. Once I do it correctly, with 'vnet1'. It works, sorry.

I should have scrapped my jail and do it from scratch.

What I actually would like to do is push interfaces from the host in to the jail (in the experiment a vlan interface), but that fails with (lib)ioc, as the syntax check expects "$interface_name:$brindge_name".

sorry for the noise.

[gronke]

Currently ioc requires a bridge interface where it can assign the epair device of the jail to. So you would require a bridge interface created on the host for each VLAN.

[igalic]

We don't support any kind of passthru?
like with other devices?
