For a first virtual machine (VM) executing on a physical machine and virtualizing a set of redundant physical adapters installed in the physical machine, a second VM is instantiated on the physical machine. A first physical adapter is reassigned from the first VM to the second VM, the first physical adapter comprising one of the set of redundant physical adapters, the reassigning performed without rebooting a first operating system executing in the first VM. A second rule configuration of the second VM is updated to match a first rule configuration of the first VM, forming an updated second VM. A hypervisor managing the physical machine is caused to redirect traffic for a first virtual adapter associated with the reassigned first physical adapter to the updated second VM.

A system for generating memory references is provided. Instructions to perform a memory data operation on a database from a computer system is received. A computing system generates a memory reference in a region of memory, wherein the memory reference is independent of where the memory is accessible by a computing system. A memory reference to a memory region on a database is stored by a computing system. A memory reference based, at least, on the memory data operation is translated. A data in the memory via the instruction to perform a memory data operation is accessed. A memory data from the database is retrieved.

Accessing persistent memory via load and store

Examples of techniques for deferred disclaim of memory pages are described herein. An aspect includes, based on freeing of a last allocation on a first memory page, placing, by a processor, the first memory page on a deferred disclaim list. Another aspect includes, based on freeing of the last allocation on the first memory page, setting, by the processor, a first hidden flag in a first page table entry corresponding to the first memory page.
