You should note that this is primarily an SELinux labelling issue.

You can use virt-install to put the images wherever you like, but you
have to label that directory and/or the images with the correct label.

On F-10 something like this should work:

chcon system_u:object_r:virt_image_t:s0 /some/dir
virt-install --disk=path=/some/dir/image,size=10 [other virt-install opts...]

'Course you have to do both of those commands as root.

virt-manager also lets you specify the path when you create
file-backed guests.
