Using external gateway for managed VMs
Hello,
I am currently using cloudstack to manage VM's on a Xenserver. My internal
guest network is 10.1.1.0/24.
For the VMs, a default route is in place of 10.1.1.1 which is a cloudstack
system vm. This means that ALL VM traffic gets routed through this
cloudstack VM before being NAT out to my enterprise network, is that
correct?
Is there a way to have an alternate configuration that skips having to
route to this cloudstack system VM?
Thanks,
-Derek

Thank you, I will investigate this. That sounds like something that I could
use. I am using puppet to automatically deploy the VMs and I wanted to be
able to use the DHCP servers user data for those nodes. I thought if I
didnt do it this way, I wouldnt get use of the cloudstack DHCP server.
Hopefully this is a solution that will work in that scenario.

You could create a shared network as this does not have NAT function so VR provides only DHCP, DNS & User Data, you then specify the Gateway when you create the network pointing it at a physical Router or L3 switch etc.
