hi,
at home I have setup a kvm virtualization lab. I have a layer 3 switch, a host with 3 nics and centos 6.3.
In the layer 3 switch I have setup a couple of vlans: vlan 1 (default), 5 (quarantaine) and 10 (out-of-band-management).
nic0 is configured in the switch as a trunk interface that sees all vlans. nic2 is an access port on vlan 5 and nic1 is not yet in the picture ;-)
eth0 is bridged to br0. It also has the host default gateway. I have also created eth0.5, br0.5, eth0.10 and br0.10 interfaces to add vm's to vlan 5 and 10 and that works, I can successfully create vms and assign them to br0.5 or br0.10 and they get ip's from a dchp server in the correct network and their traffic is correctly routed in the switch (inter vlan routing works). I can access the vms from my workstation on on vlan 1.
Now I configure eth2 with an ip address in the range of vlan 5 (in the switch it is an access port in vlan 5). This is the ifcfg-eth2 file:
DEVICE="eth2" HWADDR="00:15:17:51:B8:AB" IPV6INIT="no" BOOTPROTO=none MTU="1500" NM_CONTROLLED="no" ONBOOT="yes" IPADDR=192.168.5.10 NETMASK=255.255.255.0 # GATEWAY=192.168.5.254
The GATEWAY parameter is now commented out, but it does not matter.
The interface on the virtualization host comes up all right. But I cannot access it from my workstation on vlan 1 when accessing it to vlan 5.
From the virtualization host I can reach the switch vlan 5 interface
which is its gateway. From the switch I can also ping the interface eth2.
The routing table on the virt host:
# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.5.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 br0 169.254.0.0 0.0.0.0 255.255.0.0 U 1003 0 0 eth2 169.254.0.0 0.0.0.0 255.255.0.0 U 1016 0 0 br0 169.254.0.0 0.0.0.0 255.255.0.0 U 1018 0 0 br_v10 169.254.0.0 0.0.0.0 255.255.0.0 U 1020 0 0 br_v5 0.0.0.0 192.168.0.254 0.0.0.0 UG 0 0 0 br0
Do you have any tips on how to reach vlan 5 on the virt host from vlan 1? -- Groeten, natxo
