Hi, I would like to announce the first release of Kemari, an open-source virtual machine synchronization mechanism for fault tolerance. It offers a feasible approach to fault tolerance that does not require the use of specific hardware or modification of applications/OS. Kemari aims to keep VMs transparently running in times of hardware failures. It transfers the state of the primary VM to the

...sues the HLT instruction by dividing down its clock rate relative to its current P-state''s input voltage and clock reference rate. When dividing the core''s clock rate down, C1-clock ramping adjusts the TSC increment so that the TSC appears to continue incrementing at the undivided clock reference rate of the current P-state. BIOS enables and configures the value of the divisor by programming the PMM7 registers in the processor''s integrated Northbridge. The operating system initiates the mechanism by issuing the HLT instruction. As each core in an AMD D...
