Creating and Deleting veth Network Adapters
By default, any Container on the Parallels server starts functioning in the
venet0
mode right after its creation. However, at any time you can create additional virtual adapters for Containers and set them to work in the bridged mode. You can do this using the
--netif_add
option of the
prlctl set
command.
Let us assume that you wish to create a new virtual adapter with the name of
eth1
in Container 101 and make it function in the bridged mode. To do this, run the following command :
# prlctl set 101 --netif_add eth1
The settings of the newly created virtual adapter are saved as the value of the
NETIF
parameter in the configuration file of Container 101 (
/etc/vz/conf/101.conf
). So, you can use the following command to display the parameters assigned to the
veth
network adapter in Container 101:
# grep NETIF /etc/vz/conf/101.conf
NETIF="ifname=eth1,mac=00:10:41:F0:AA:B6,host_mac=00:18:51:A0:8A:D7"
As you can see, the parameters set for the
veth
virtual network adapter during its creation are the following:
-
ifname
: the name set for the
veth
Ethernet interface in Container 101. You specified this name when creating the Container virtual network adapter. Usually, names of Ethernet interfaces in Containers are set in the form of
eth
Ad_N
where
Ad_N
denotes the index number of the created adapter (for example,
eth0
or
eth1
). However, you can choose any other name you like and specify it during the virtual adapter creation.
-
mac
: the MAC address assigned to the
veth
Ethernet interface in Container 101.
-
host_mac
: the MAC address assigned to the
veth
Ethernet interface on the Parallels server.
ifname
is the only mandatory parameter that you need to specify when creating a Container virtual network adapter. All the other parameters are optional and generated by Parallels Cloud Server automatically, if not indicated.
At any time, you can remove the
veth
virtual network adapter from Container 101 by executing the following command:
# prlctl set 101 --netif_del eth1
