No option in Virt-Manager for selecting Ubuntu 13.04 as a version
 

Hi,

I installed KVM for the first time on my Ubuntu 13.04 server and setup bridged networking as well to accomadate the plethora of servers I plan to run on my box. I've been a linux enthusiast now for some time but recently have been trying to take my skills a step further.

With that said I've installed Virt-Manager in an effort to create and administer the VMs. I'm planning on creating my first VM and want to setup a DNS server using Ubuntu 13.04 since that is my host operating system and given that I've had success in setting up Bind on this particular distribution.

So, I started up Virt-Manager over an -X window SSH session and began creating a VM. I then selected my ISO image of Ubuntu 13.04 Server, OS type:Linux, and then under Version there was no listing for 13.04 however there were a host of others. See attached Screenshot.

I guess my question is why was 13.04 not included in the list of available version or should I just select generic 2.6.x kernel. Is there a way to add additional distros/oses to the list (it really is very expansive) or should I just be doing this all from the terminal.

Any thoughts or suggestions welcome. :)

I'm guessing that the version of Virt-Manager included in Ubuntu 13.04 was produced before Ubuntu 13.04 came out, since it was packaged for it. Therefore the developers can't possibly have known what 13.04 would look like.
My (semi-educated*) guess is that if your guest version is higher than any of the choices you choose the highest version available for that distribution. So you'd go with 12.10. This is likely just used by Virt-Manager to decide upon whether to use SATA or IDE disks and how much RAM to suggest you use so it probably won't matter what you choose. However, should you choose just the generic 2.6 I suspect it may do something like use IDE disks and suggest you
allocate 256MB of RAM.

*I use VirtualBox and have played with a couple VMware players.

Makes sense to me.
 

I had kind of suspected as much but wanted confirmation. Now that I've had some time to think it over I may end up picking a distribution that is more lightweight since I only plan to use that particular VM as a DNS server.

You could always install Ubuntu without a desktop environment, if that's what you're used to. Debian would be familiar too, apart from having no sudo by default.
