| Doc Text: |
Prior to this update, Red Hat Enterprise Linux Xen (up to version 5.6) did not hide 1 GB pages and RDTSCP (enumeration features of CPUID), causing guest soft lock ups on AMD hosts when the guest's memory was greater than 8 GB. With this update, a Red Hat Enterprise Linux 6 HVM (Hardware Virtual Machine) guest is able to run on Red Hat Enterprise Linux Xen 5.6 and lower.
