Credit-Based Runtime Placement of Virtual Machines on a Single NUMA System for QoS of Data Access Performance

While a NUMA system is being widely used as a target machine for virtualization, each data access request produced by a virtual machine (VM) on the NUMA system may have a different access time depending on not only remote access condition, but also shared resource contentions. Mainly due to this, each VM running on the NUMA system will have irregular data access performance at different times. Bec...
