My internal DNS is working (I installed dnsmasq on the management server and set it to listen on the internal IP address 10.1.40.3). From the hosts and guests, pinging the management server by name goes to the correct internal address. Where do the arguements in /var/cache/cloud/cmdline come from? That appears to be the source of the problem. mgmtcidr=XX.47.90.0/24 localgw=10.1.40.1 host=xx.47.90.4
The localgw is correct, but the mgmtcidr and host are wrong (they point to public instead of local) John On Fri, Oct 24, 2014 at 10:05 AM, Andrija Panic <[email protected]> wrote: > and internal DNS - it must be accessible/routable from mgmt network - when > I set internal dns to be 8.8.8.8 then SSVM check was failing, and I had bad > routes as you do at the moment... > So no routes for internal DNS should be added at all in my opinion, it's is > on the administarator of the CS to allow public IP (whatever it is private > ro public IP) to be reachable/routable from mgmt network... > > On 24 October 2014 16:03, Andrija Panic <[email protected]> wrote: > > > I had the same/similar issues, when my mgmt server and agents (bridge on > > them) had public IP...I add host as 10.x,x,x to the cloudstack, and the > > cs-agent reads the public IP address from the bridge and defines that > > public IP as the host IP inside cloudstack (acs 4.4) > > > > On 24 October 2014 01:06, John Pletka <[email protected]> wrote: > > > >> This is probably something simple, but I can't find it. > >> *TLDR: how to send guests the internal IP of the management server > instead > >> of public?* > >> > >> My setup: > >> > >> xx.47.90.0/24 => cloud-public > >> 10.1.40.0/24 => cloud-private (SAN + MGMT) > >> > >> Management server: xx.47.90.4 (public IP) and 10.1.40.4 (private IP) > >> > >> I'm trying to run the storage server health check > >> (/usr/local/cloud/systemvm/ssvm-check.sh) and it is failing pinging the > >> management server. > >> > >> Good: DNS resolves download.cloud.com > >> ================================================ > >> nfs is currently mounted > >> ================================================ > >> Management server is XX.47.90.4.
