Zone DNS, Virtual Routers, and DHCP

[Zack Payton <zp...@gmail.com>]

Hi dudes,

I'm trying to host DNS off of one of the VMs that I have here in the KVM
cluster.
Any way to set a static IP for a server (or more preferably a static DHCP
lease)?
I tried changing the zone DNS IP to that of my DNS VM but I have to restart
the virtual routers which then causes my DNS VM to get a new IP.  Is the
only real solution here to run my DNS on bare metal?

Thanks,
Z

Z,

For public DNS simply point it at 8.8.8.8 and 8.8.4.4

The internal DNS should not really be running in the cloud as it is used by components of the cloud and therefore may not be available when it's required, e.g.  during a power on after a outage etc.

We always virtualise the CloudStack Management & MySql servers, and if new DNS servers are required simply add 2 Internal DNS VMs at the same time.  These VMs run on a set if Hosts which are not part of the Cloud.
