Hi, this is actually a bug in virt-manager which was fixed in upstream
by these commits:

    2099a1946e22b62d31b954dc3e7b813404c2d019
    93085d2b9d4a3dd6cbb9edfeae9b6cefee9419c1
    8181e8609867fe6ed101e48212d42a1c38373539

To work-around this issue cancel the installation and start it again.
There is no official release of virt-manager with that fix included, we
should probably make the release.
