[PVE-User] Create a second interface in a VM

[Gilberto Martins]

Hi Marco.

I have already seen the video. It explain how to add a bridge to the
host. This is not the question, for I need to add a second interface
to the virtual machine. My ProxMox server has already 2 bridges, as
shown below:

v01:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether d8:d3:85:6d:14:94 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::dad3:85ff:fe6d:1494/64 scope link
       valid_lft forever preferred_lft forever
3: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast
state DOWN qlen 1000
    link/ether 00:04:75:8c:6a:ff brd ff:ff:ff:ff:ff:ff
4: vmbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue
state UNKNOWN
    link/ether d8:d3:85:6d:14:94 brd ff:ff:ff:ff:ff:ff
    inet 172.21.43.99/25 brd 172.21.43.127 scope global vmbr0
    inet6 fe80::dad3:85ff:fe6d:1494/64 scope link
       valid_lft forever preferred_lft forever
5: vmbr1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue
state UNKNOWN
    link/ether 00:04:75:8c:6a:ff brd ff:ff:ff:ff:ff:ff
    inet 172.21.43.20/25 brd 172.21.43.127 scope global vmbr1
    inet6 fe80::204:75ff:fe8c:6aff/64 scope link
       valid_lft forever preferred_lft forever
6: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc
noqueue state UNKNOWN
    link/void
    inet6 fe80::1/128 scope link
       valid_lft forever preferred_lft forever

And here is my VM network configuration:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: venet0: <BROADCAST,POINTOPOINT,NOARP> mtu 1500 qdisc noop state DOWN
    link/void
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
    link/ether 1a:b5:26:1f:0c:45 brd ff:ff:ff:ff:ff:ff
    inet 172.21.43.10/25 brd 172.21.43.127 scope global eth0
    inet6 fe80::18b5:26ff:fe1f:c45/64 scope link
       valid_lft forever preferred_lft forever


My doubt is: since I have 2 bridged interfaces, how to add an extra
interface in the virtual machine ?


Thanks for the help.
