 You should see either vmx or svm in the output.

+Now, install the basic packages needed, a couple of utilities, but not all the extra crud. //netcat-openbsd// is only needed if you're going to cluster and migrate virtuals from one hypervisor to another, from what I can tell. **virt-top** is a nice little //top// for seeing what is running and what resources they are using in real time.

 Other useful options are
   * --dry-run # don't really do it
+  * --print-xml # this will dump the XML file instead of running the command. This is very useful when installing virtuals that will need more than one CDROM drive as you can then edit the XML file to add it. **Note**: the resulting XML is doubled, ie has two copies of the XML in it and must be edited before use.
   * --controller virtio-scsi # this is specific to KVM, but faster there
   * osinfo-query os # this shows the OS's available for the --os-variant flag
 most of the parameters are self evident, but I'll quickly talk about why I did some of them.
