If your machine does not have VT support, you will only be able to install a
PV guest, and the only way to install a PV guest on linux is using a direct
kernel/initrd boot (basically a URL install).

If you have an install DVD, you can mount it and export it over http on your
local machine, then point virt-manager at that.
