Yes, the qemu RPMs in centos & RHEL have disabled support for http://
protocol, however, I expect that to immediately fail when trying to
start the guest. eg

# /usr/libexec/qemu-kvm  -drive file=http://example.com/foo/bar -accel tcg
qemu-kvm: -drive file=http://example.com/foo/bar: Driver 'http' is not whitelisted

so I'm puzzelled why your guest successfully started at all with a
http protocol in use.

Are you able to share your QEMU log from /var/log/libvirt/qemu/$GUESTNAME.log
from a VM that fails to launch with http ?
