I have seen this problem a lot many times when people try to run linux VMs on Xen host which does not have Intel VT feature. Once Xen is installed, they are unable to run any VM since by default Xen keeps the virtualization type to HVM.
However you can run VMs on this host by following the following trick:-
You need to get VMs which are Paravirtualized. You can get them by creating them on a host which has VT feature, then making them Paravirtualized and then exporting them from that host and importing on the host which does not have intel VT feature. Using this, you will be able to run Paravirtualized VMs on hosts which does not have Intel VT feature. I have tried this and it worked in my case. Thought of sharing this with larger audience as it might help someone in need. To create paravirtualized Ubuntu VM, see my post link: Creating Paravirtualize Ubuntu VM
