We just bought a new server that supports the Conroe CPU model, and I am trying to install Server 2012 R2 without luck. I keep getting error code 0x00C4. The problem is while Windows is still to load into its pre-installation environment it cashes and then immediately resets. This is a continuous loop. I have found a way to install Server 2012 R2.

Re: [ovirt-users] FQDN for vm creating with hosted-engine
--- FQDN or fully qualified domain name means that you have to reserve in your DNS a name corresponding to IP received by HE VM from DHCP. IP address should be reserved for the VM at DHCP. I advise not to use manual IP to FQDN at your host, as this will lead to many confusions, especially when you'll have more than a single host machine, but you always can configure at your /etc/hosts file the FQDN corresponding to IP address given to HE VM. --- Thanks for the explanation. Now I understand what FQDN is for Ovirt. Is there any problem if I do not use the naming convention like aaa.bbb.ccc, but only aaa? Also I am some confused for the above explanation. Here it said the IP for VM is better to be got from DHCP rather than manual IP. If so, do this mean I need to change all /etc/hosts file of all virt nodes to update the IP for the FQDN for engine VM? What is the confusions if I use manual IP rather than DHCP for engine VM?

Does it mean the > hostname of VM host? In my case, it is compute2-2. Do you refer to the following: Please provide the FQDN for the engine you would like to use. This needs to match the FQDN that you will use for the engine installation within the VM. Note: This will be the FQDN of the VM you are now going to create, it should not point to the base host or to any other existing machine. Engine FQDN: ? We recently changed this text to be so, due to [3]. If you still do not find it easy to understand, please suggest better wording. Thanks! The "Engine FQDN" is the name that is used by others to refer to the machine on which the engine runs. In this context it's the name of the VM. This does not have to be the hostname of that machine - the output of the command 'hostname' there. E.g. you might want to have a hostname 'purple.example.com' but connect to it as 'my-engine.example.com'. You'd probably add to the dns an A and a PTR record for 'purple', and a CNAME record for 'my-engine'. You should then input at this prompt, as well as the one during engine-setup inside this vm, 'my-engine.example.com'. See [1] [2] as examples for naming conventions.
