Hello,

i have a problem regarding my network setup between my vm's

Here are my settings:

PROXMOX HOST:

auto vmbr0
iface vmbr0 inet static
address 192.168.10.2
netmask 255.255.255.0
gateway 192.168.10.1
bridge_ports eth0
bridge_stp off
bridge_fd 0

auto vmbr1
iface vmbr1 inet static
address 10.10.10.1
netmask 255.255.255.0
bridge_ports none
bridge_stp off
bridge_fd 0

VM1:

allow-hotplug eth0
iface eth0 inet static
address 192.168.10.3
netmask 255.255.255.0
network 192.168.10.0
broadcast 192.168.10.254
gateway 3192.168.10.1


auto eth1
iface eth1 inet static
address 10.10.10.2
netmask 255.255.255.0
network 10.10.10.0
gateway 10.10.10.1


VM2:

allow-hotplug eth0
iface eth0 inet static
address 192.168.10.4
netmask 255.255.255.0
network 192.168.10.0
broadcast 192.168.10.254
gateway 192.168.10.1

allow-hotplug eth1
iface eth1 inet static
address 10.10.10.3
netmask 255.255.255.0
network 10.10.10.0
gateway 10.10.10.1

The first problem i had was after a reboot of the virtual machine my second interface (10.10.*.*) was not enable and i fixed it with auto eth1 but after i did this the whole vm was not reachable anymore after the reboot.

The second problem is that they cant ping eachother via eth1. If i do a tcpdump on the second vm there comes

17:31:49.064068 ARP, Request who-has 10.10.10.3 tell 10.10.10.2, length 28

Does anybody know what could be the problem ?



EDIT: There are other vm's with the same setup and everything works fine with them only the newly created one is doing problems

ouch

are you sure the eth1 devices of your VM are on the vmbr1 bridge ?
you can check with

brctl show vmbr1
