Very good Hi, I come to you because it is an issue that has me alittle desperate, I do not know what happens ...


Anyway, I think a KVM virtual machine, install debian and add
Two network interfaces:


eth0 -> 192.168.0.33 -> vmbr0
eth1 -> 192.168.0.34 -> vmbr0




That is, give it 2 ips from my local range bridgeando the same interface
network. This works well, the network interfaces are configured within
debian:


what car
inet loopback iface


# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.0.33
netmask 255.255.0.0
gateway 192.168.0.1


auto eth1
iface eth1 inet static
address 192.168.0.34
netmask 255.255.0.0




Now comes the weird ... From the web interface Proxmox, I can
disconnect network interfaces mapped to the VM debian hot
and, in theory, if the disconnect could not perform such as a
ping ...


I tell you what I get:


- While I ping 192.168.0.33, I disconnect the interface vmbr0 ->
net0 network from Proxmox and ping stops, I go back and enable
continuous ping, that well.


- The problem comes with the interface 2, if I ping 192.168.0.34
and disconnect the interface vmbr0 -> net1, continuous ping ... I have to
vmbr0 disable interface -> net0 to cut the ping
192.168.0.34 and it should not be so ...


That is, if the problem is not mapped as well. I tried it in
Proxmox several different versions and different is the same.
Also different OSes.


I do not know if it's a problem or Proxmox KVM ... I sense that will be of KVM.


A picture is worth a thousand words...

This is normal (and not related to proxmox), both interfaces are in the same network 192.168.0.0/16.

So, so if you ping interface2, in = interface2 and out=interface1

Until you manage custom routes, this setup will never work
