I'm trying to design an SCVMM (2012 SP1) service template that contains several machines joined in a domain, but the trick is that the very domain controller is also in the template. Ie. the template contains a machine that will become the AD and several machines which will join. Since the domain does no exists during deployment, the template declares all machines as part of a Workgroup. Application profile Pre-Install scripts do the work of running Install-ADDSForest on the AD and Add-Computer on the machines that join. With proper deployment order this works fine, but I have a problem as the next Pre-Install scripts start failing now:

Error (22725)
SCVMM received computer name <machine>.<domain> for vm <...>. Expected computer name is <machine>.

Recommended Action
Ensure that the vm has joined the right domain or workgroup and then retry the operation.

Oops. Since the rename occurred in the application scripts, SCVMM is not aware of it and is crying fault. But this is a chicken and egg problem...

Any suggestion of how to solve this problem?

My goal is to be able to add/drop subdomains for a multi-tenant app via Route53: tenant.example.com. Account provisioning should place the new tenant on a hosting node and then add the newly onboarded tenant subdomain to Route53. The parent DNS is currently handled by a 3rd party (dnsmadeeasy). Currently DNS provider has something like this:

example.com -> A -> <someIP>
example.com -> MX -> <mailhost>
mail.example.com -> CNAME ->  <mailhost>
www.example.com -> CNAME -> example.com
example.com -> NS -> <several provider name servers>

I'm also pretty sure the DNS parent provider (dnsmadeeasy) has a SOA record too which is implicit (not shown in management UI). So I did the following:

  • I added a wildcard hosted zone in Route53: *.example.com. This has 5 records right now, 4 NS records with various name servers and a SOA record

  • I added the Route53 NS records to the parent DNS provider (dnsmadeeasy)

    *.example.com -> NS -> <Route53 name server for hostzone above>

My thinking was that now I can start adding A records in the Route53 zone for each tenant:

tenant1.example.com -> A -> <tenant1 hosting IP>
tenant2.example.com -> A -> <tenant1 hosting IP>
...

But trying to add A records in Route53 results in tenant1.\052.example.com which is not what I want. And I'm not even sure it will work.

My question is whether this is a correct way to go ahead or I'm of the wrong path.
