Subject VMs unable to reach public network
Date Tue, 07 Oct 2014 18:07:23 GMT
I have a new CloudStack install and am facing the situation where guests
can't access the public network.  It assigns the public IP and gateway
correctly, but when I ssh into the VM, it can only reach the private side.
Specifically, I'm testing the secondary storage VM.  Sorry for the config
dump below, but hopefully something will stand out.

For my setup I have:
1) Cisco 4948 switch.   1/2 the ports are a private VLAN 10.1.40.0.  1/2
the ports are public and connect upstream to a router.
2) 3 host machines running XenServer 6.2 with dual NICs.  ETH0 -> private
VLAN, ETH1=> public side of the switch
3) The Management is on a 4th server, dual nic and communicates to public
and private fine
4) Each of the host machines has a private address assigned to xenbr0
(10.1.40.4, 10.1.40.5, 10.1.40.6).  Gateway is 10.1.40.1, which is owned by
the switch VLAN
5) The Public range is setup as xx.47.90.0/24 (.10-.254 available to guests)
6) The host servers can't reach the public network because I have not
assigned a public address to xenbr1
