Can local rules defined in RHEL6 be used as it is in RHEL7 or we need to do changes with respect to syntax before using them in RHEL7.

On rackspace, centos 6 and 7 have the same

 md5sum /etc/udev/rules.d/z10-xen-vcpu-hotplug.rules


ACTION=="add", SUBSYSTEM=="cpu", RUN+="/bin/sh -c '[ ! -e. /sys$devpath/online ] || echo 1 > /sys$devpath/online'"
