Subject Re: Enable virtio for Ubuntu 13.04 template?
Date Wed, 09 Oct 2013 09:03:27 GMT
Hi Kirk,

Good day to you, and thank you for your e-mail reply.

Can I confirm that the OS type determines the network controller as well?

I read from CloudStack documentation that it's not advisable to use a lower
version of the OS if the actual version is not available?

http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.2.0/html/Admin_Guide/create-template-from-existing-vm.html

===
Note: Generally you should not choose an older version of the OS than the
version in the image. For example, choosing CentOS 5.4 to support a CentOS
6.2 image will in general not work. In those cases you should choose Other.

Looking forward to your reply, thank you.

Cheers.
