I am using proxmox ve 1.6
I have installed a debian lenny in a KVM
I am using an rtl8139 interface Model on bridge vmbr1
Its IP is 192.168.20.16.
This vm is running apache tomcat with sometimes quite heavy network load.
And sometimes, network in this vm stop running.
I have to log with the VNC console to make a ifconfig eth0 down;ifconfig eth0 up to make it works again.
I have found nothing in the logs, neither on the VM neither on the host
There are other VM on this proxmox, some with kvm, other with openvz. And they have not this problem.
I think the network load is related to the problem :)
Is there a specific configuration to do on the host ?

here is my network configuration on host proxmox:
# for Routing
auto vmbr1
iface vmbr1 inet static
address 192.168.20.1
netmask 255.255.255.0
bridge_ports none
bridge_stp off
bridge_fd 0
post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up iptables -t nat -A POSTROUTING -s '192.168.20.0/24' -o vmbr0 -j MASQUERADE
post-down iptables -t nat -D POSTROUTING -s '192.168.20.0/24' -o vmbr0 -j MASQUERADE



# vmbr0: Bridging. Make sure to use only MAC adresses that were assigned to you.
auto vmbr0
iface vmbr0 inet static
address XXX.YYY.ZZZ.AAA
netmask 255.255.255.0
network XXX.YYY.ZZZ.0
broadcast XXX.YYY.ZZZ.255
gateway XXX.YYY.ZZZ.254
bridge_ports eth0
bridge_stp off
bridge_fd 0

Thanks, Jean-Noel
