Nice catch! This is fixed upstream now:

Comment 3 zhoujunqin 2019-07-15 03:36:55 UTC

I can reproduce this issue with build:
virt-manager-common-2.0.0-5.el8.noarch

Then try to verify this bug with new build:
virt-manager-2.2.0-2.el8.noarch
virt-install-2.2.0-2.el8.noarch
libvirt-4.5.0-24.module+el8.1.0+3205+41ff0a42.x86_64
qemu-kvm-2.12.0-77.module+el8.1.0+3382+49219945.x86_64

Steps:
1, Create a new vm follow giving the os a different name, and different image, others are the same, especially make sure the MAC is completely the same as the prepared one.
2. After Click "Finish".

Result: An error window pops up with information:
Error applying changes: The MAC address '52:54:00:24:b8:d7' is in use by another virtual machine.

Above result is as expected, so I move this bug from ON_QA to VERIFIED, thanks.
