I have a problem with ethernet connetion from VM to local net and internet.
I have physical server with two ethernets.
I created a Bound with eth0-eth1 and two bridges:
(vmbr0 -> bond0) For Proxmox web admin and ssh conection to de host server (192.168.0.10)
and
(vmbr1 -> bond0). For KVM virtual machines. In VM set ethernet local configuration.
The visión from Poxmox web server is:

This is my /etc/network/interface in host server:
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

auto eth1
iface eth1 inet manual

auto bond0
iface bond0 inet manual
slaves eth0 eth1
bond_miimon 100
bond_mode 802.3ad

auto vmbr0
iface vmbr0 inet static
address 192.168.0.10
netmask 255.255.255.0
gateway 192.168.0.3
bridge_ports bond0
bridge_stp off
bridge_fd 0

auto vmbr1
iface vmbr1 inet manual
bridge_ports bond0
bridge_stp off
bridge_fd 0

Any sugestion about my problem.
Tnks.

pls only one post (you posted the same 4 times)

due to spam attacks, we moderate threads and if you post multiple times the same, you just add extra work here.
 
The guest VM not have connection with local network an internet. Only have ping to himself and host proxmox machine.
All VM have ip of range 192.168.0.0/24 as host proxmox (192.168.0.10).
 
Maybe your switch is not properly configured for bondage.
Remove the bondage and try with eth0 -> vmbr0 first
 
If remove bond0 and asign eth0->vmbr0 and eth1->vmbr1 work fine.
I can access to proxmox web panel thru vmbr0 (192.168.0.10) and VM's thru vmbr1 (192.168.0.12 - 192.168.0.13).

auto vmbr0

address 192.168.0.10
netmask 255.255.255.0
gateway 192.168.0.3
bridge_ports eth0
bridge_stp off
bridge_fd 0

auto vmbr1

bridge_ports eth1

bridge_fd 0
I need configure a physical switch for bounding?
Thanks.

for 802.3ad bonding, yes. (and you need switchs that support that).
