Nesting RHEL7 KVM on VMware Workstation 12

In this post I discuss how to enable a Red Hat Enterprise Linux VM to use KVM when installed on top of VMware Workstation version 8 or later.

How to Determine Hardware Mode of Intel CPU

Consider the following output: # grep flags /proc/cpuinfo flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx rdtscp lm constant_tsc pni monitor ssse3 lahf_lm How can you the maximum size of a long that can be used with this CPU? The answer is 64-bit because of the presence of the lm flag. The following flags can be used to determine the maximum size of a long for a CPU: lm – Long Mode (64 bits) tm – Protected mode (32-bit) rm – Real Mode

Zero Power Optical Drive Support

Zero power optical drive support (ZPODD) is finally coming to the Linux kernel. Support for ZPODD will be available in the 3.9 kernel. ZPODD aims to reduce power consumption on SATA Slimline Optical Disk Drives (ODDs). Both drawer and slot OODs are supported. The goal is to cut off the power supply to the optical drive when it is not in use. When the user wants to use the drive, the power supply is resumed. For more information, see the Mount Fuji 8 Revision 1.0 Specification. The Mount Fuji group consists of optical disc drive manufacturers, operating system vendors, independent
