Hi,


I have a strange problem with my config.
The problem :
If I start VM1, it connect without any problem but if i start VM2 (in a second time) VM2 it can't connect.
If I start VM2, it connect without any problem but if i start VM1 (in a second time) VM1 it can't connect.
( I have checked the MAC of interfaces of VM1 and 2, this is not the same)


=> in other words : first VM to boot win !

ON THE HOST :
eth0 : vmbr0 (crossover cable for cluster)
eth1 : vmbr99 (management interface)
eth2
eth3 : bond0 (production interfaces)


below, my /etc/network/interfaces :

Code: 
auto lo
iface lo inet loopback
iface eth0 inet manual
iface eth1 inet manual
iface eth2 inet manual
iface eth3 inet manual



auto bond0
iface bond0 inet manual
        slaves eth2 eth3
        bond_miimon 100
        bond_mode 802.3ad


auto vmbr0
iface vmbr0 inet static
	address 10.0.0.1
	netmask 255.255.255.0
	gateway 10.0.0.2
	bridge_ports eth0
	bridge_stp off
	bridge_fd 0
	pre-up ifconfig eth0 mtu 9000


auto vmbr99
iface vmbr99 inet static
	address 192.168.149.101
	netmask 255.255.255.0
	gateway 192.168.149.251
	bridge_ports eth1
	bridge_stp off
	bridge_fd 0


]auto vmbr10
iface vmbr10 inet manual
	bridge_ports bond0
	bridge_stp off
	bridge_fd 0

below, ifconfig on the host after the 2 vms start with bridge tag per vlan (vmbr10v150 and vmbr10v4090) :

therefore interfaces, bond and bridges seems to be ok ?!

i don't think the problem come to the config of my switch or router because each vlan work fine if i start only one VM...

VM1:
add: 192.168.150.201/24
gw : 192.168.150.251


VM2:
add : 192.168.152.201/24
gw : 192.168.152.251


SWITCH : Cisco SG-300
LAG 1(front of eth2 eth3) is in Trunk (vlan 150, 4090)


ROUTER : Cisco ISA 500
vlan 150 and 4090 (dmz) are ok


SWITCH to ROUTER :
one link in trunk for vlan150, 151, etc
one link in access for dmz vlan4090


Any suggestion ?
I can not see anything now...

Thanks,
GR
 
Ok, i have find..

That's the bond_mode was wrong.
I have passed my bond0 in "balance-rr" and now it's good.

On my switch, lacp is disabled on my LAG1 (front off bond0).
So, in fact no problem with my proxmox config.

Regards,
GR
