Well basically the supported OS variant is here only to optimize 
libvirt/qemu setting (caches, drives, defaul cpus, default mem) and it's 
not really mandatory. One can use "fedora-unknown" or whatever supported 
version ("fedora16") and the fedora 19 should work properly.

Simple answer
-------------

To avoid this problem you need to tell avocado to use fedora17 libvirt 
profile. You can do this from the command line using "--vt-extra-params 
os_variant=fedora17":

     $ avocado run 
io-github-autotest-qemu.unattended_install.import.import.default_install.aio_native 
io-github-autotest-libvirt.virsh.create.none remove_guest.without_disk 
--vt-type libvirt --vt-guest-os JeOS.19 --vt-extra-params 
os_variant=fedora17

Proper answer
-------------

The os_variant is mapped by configuration files. The JeOS.19 one is in 
$avocado-vt/shared/cfg/guest-os/Linux/Fedora/19

so feel free to replace the "os_variant = fedora19" with "os_variant = 
fedora17" and run without any modifications on the command line. You can 
do the same for all other images.

This image will most certainly not work. Easier way to get freshly 
installed image is to use "avocado run 
unattended_install.cdrom.extra_cdrom_ks.default_install.aio_threads 
--vt-guest-os XXX" where you specify the desired guest-os and avocado 
will run kickstart installation for you using qemu.

All guest os' are defined in the config files (as mentioned earlier). 
You can add any distribution by copying similar profile and changing the 
names. But it's probably easier to use the profile and put the image of 
the resulting name in place. There is no verification.

Yes, not all versions were produced. Btw with JeOS you have only limited 
set of tests available so it's better to use full "fedora.XX" version 
(or centos). As mentioned earlier, there is no verification so simply 
putting the image of the right name into the right location makes the 
image available for testing.
