danny webb commented on CLOUDSTACK-2008:
----------------------------------------

ok

I will try to walk you through my network setup (which may be wrong).  I modified the steps
from the networking section of this to get my setup working:

https://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.0.1-incubating/html/Installation_Guide/hypervisor-kvm-install-flow.html
(specifically the network section)

so on the virt hosts I have 3 bonds setup in /etc/sysconfig/network-scripts (ie out of cloudstack
control):

[root@slo-cnkvm002 ~]# ifconfig -a bond0.50
bond0.50  Link encap:Ethernet  HWaddr 00:17:A4:77:48:30  
          inet6 addr: fe80::217:a4ff:fe77:4830/64 Scope:Link

          TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:4801038 (4.5 MiB)  TX bytes:648 (648.0 b)

[root@slo-cnkvm002 ~]# ifconfig -a bond0.60
bond0.60  Link encap:Ethernet  HWaddr 00:17:A4:77:48:30  
          inet6 addr: fe80::217:a4ff:fe77:4830/64 Scope:Link

          RX bytes:7104994786 (6.6 GiB)  TX bytes:3705458318 (3.4 GiB)

[root@slo-cnkvm002 ~]# ifconfig -a bond0.70
bond0.70  Link encap:Ethernet  HWaddr 00:17:A4:77:48:30  
          inet6 addr: fe80::217:a4ff:fe77:4830/64 Scope:Link
          UP BROADCAST RUNNING MASTER MULTICAST  MTU:1500  Metric:1
          RX packets:446772 errors:0 dropped:0 overruns:0 frame:0
          TX packets:112149 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:493027550 (470.1 MiB)  TX bytes:10803061 (10.3 MiB)

I then setup one cloudbrX (cloudbr0) device on bond0.60 setup in /etc/sysconfig/network-scripts
(ie out of cloudstack control).  I didn't setup a cloudbr1 device.

cloudbr0  Link encap:Ethernet  HWaddr 00:17:A4:77:48:30  
          inet addr:172.18.102.6  Bcast:172.18.102.255  Mask:255.255.255.0
          inet6 addr: fe80::217:a4ff:fe77:4830/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:5094443 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2725564 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:5825135265 (5.4 GiB)  TX bytes:1382551076 (1.2 GiB)


In this setup I can ping my system vms fine on their "public" interface which is on the cloudVirBr70
setup by cloudstack and on their management interface which is on cloudbr0.  

my network vlan setup is as such:

vlan 50  nameif cloud-internal ip address 172.18.101.1 255.255.255.0 zone guest cidr (set
when setting up the zone, but won't really use as will use the guest networks below)
vlan 60  nameif cloud-admin    ip address 172.18.102.1 255.255.255.0 management 
vlan 70  nameif cloud-dmz      ip address 172.18.103.1 255.255.255.0 public

## two additional guest networks setup under infrastructure -> zone -> physical network
-> guest network

vlan 80	 nameif cloud-proddmz   ip address 10.10.10.0 255.255.255.0 
vlan 90	 nameif cloud-devdmz    ip address 10.10.11.0 255.255.255.0

not sure if that helps you.

> Hi,
> I have setup a cloudstack instance where my "root" eth device is a vlan tagged bond0.60
(as the network I am on has a different default VLAN id than my test vlans).

> when it went to setup a new guest network (with a vlan id of 80) it created it ontop
of the bond0.60 like:

>     cloud0          8000.000000000000       no             
>     cloudVirBr80            8000.0017a477483c       no              bond0.60.80

> which doesn't seem to work and I am pretty sure is syntactically wrong.  I can't ping
any guests that come up on that network.  When creating new devices it should I believe be
creating them off of the base eth device (ie eth0, or bond0).
