Networking question
HI All,
It gets confusing sometime but it will be nice if someone can give an exact table of which system vm ( Virtual Router, Console Proxy, Secondary Storage ) has vifs in which networks ( public, private, guest ) in the different zones (Basic and Advanced).
Public Nw -> Traffic sent to this network will be sent to publicly routable network
Private Nw -> Internal traffic between XS hosts, system vms
Guest Nw -> Internal traffic between guest vms of an account
Basic Zone:
VR ->
SS VM ->
CP VM ->
Basic Zone with EIP/ELB:
VR ->
SS VM ->
CP VM ->
Advanced Zone:
VR ->
SS VM ->
CP VM ->
e.g. in all the three cases VR has a vif in all the three networks.
VR -> public, private, guest
Please add or correct if I missed anything.
Thanks,
Deepak

For XenServer:
- the management server "proxies" commands to the VR by using a host
plugin. The host plugin communicates on a link local port to the VR/other
system vms.
For KVM
- almost similar to XS, but no plugins are used. The java agent resource
runs on the host and communicates on the link local port to the VR or
other system vms
For VMWare:
- system vms acquire an ip on the management network of the pod they are
running in. Management server makes ssh calls to this ip.

Apologies for the late response. None of the virtual routers I have spun up have ever been on the management network. I haven't dug into it too deeply but from what I can gather based on the vNICs assigned the management server has the host backdoor in through the link-local address and issues commands that way.

Thanks, but in the pdf of System VMs, VR is not shown in the management network. Is this correct ? How is management server supposed to talk to VR in this case ?
