The two are unrelated. Any supported guest OS can be hosted on any
supported host OS (modulo any bugs that might exist in the specific
version of qemu on your host).

When you are defining the new virtual machine, select "Import existing
image", then select the ISO image. (If you instead select "Local install
media (ISO image or CDROM), virt-manager will boot *once* from the ISO,
then reconfigure the guest to boot from a hard disk the next time.)
