VirtualBox 4.3.8 Officially Released with Support for X.Org Server 1.15

For Linux, the new version introduces support for X.Org Server 1.15, fixes CPU hot-remove issues that ocured on newer versions of the Linux kernel, and supports Red Hat Enterprise Linux 6.5 kernels. Additionally, the physical package ID is now taken under consideration when determining the number of physical CPU cores of a Linux host, and it will no longer write warning messages in the kernel log if memory allocation fails on both Linux guests and hosts.
