That is because virt-manager expects a kernel/DT/etc image rather than 
an ISO like aarch64/x86/etc.

Its actually pretty easy to run the armv7 emulation from the command 
line with a uefi firmare blob (IMHO this should be an option in 
virt-manager). The key is using the -cpu host,aarch64=off flag. Here is 
a complete command line to start a fedora image. Obviously you need the 
aarch64 qemu, the armv7 efi package, and probably a few things i'm not 
remembering installed.


"/usr/bin/qemu-system-aarch64 -name guest=fedora30arhfp -machine 
virt-3.0,accel=kvm,gic-version=2 -cpu host,aarch64=off -m 2048  -smp 
1,sockets=1,cores=1,threads=1 -drive 
file=/usr/share/edk2/arm/QEMU_EFI-pflash.raw,if=pflash,format=raw,unit=0,readonly=on 
-drive 
file=/var/lib/libvirt/qemu/nvram/Fedora-Minimal-30-20190223.n.0.armhfp_VARS.fd,if=pflash,format=raw,unit=1
