Subject RE: Unable to laucn system VM
Date Thu, 11 Jul 2013 13:40:13 GMT
The Internal DNS server settings provide name resolution for the internal infrastructure. 
For example when the SSVM attempts to resolve the global setting 'host', which should be the
FQDN of the Load Balancer VIP for your management servers, or when it resolves the FQDN of
your secondary storage nodes etc.

The external DNS Servers are used by Guest VMs to resolve public internet addresses

Geoff,

>6. Did you specify a real DNS Server IP for the Internal DNS Server, and
does it respond to PINGs via the Management Network

Just interested, why does system vms try to reach internal dns servers via
management network, what is the purpose of separate internal dns servers
instead of public dns servers ? (I did not figured this out from
documentation)
