VirtIO Memory Ballooning – – Open Source Software Developer

WebVirtIO provides Memory Ballooning: the host system can reclaim memory from virtual machines (VM) by telling them to give back part of their memory to the host system. This is achieved by inflating the memory balloon inside the VM, which reduced the memory available to other tasks inside the VM. Which memory pages are given back is the … Magnetic storage in the form of wire recording—audio recording on a wire—was publicized by Oberlin Smith in the Sept 8, 1888 issue of Electrical World. Smith had previously filed a patent in September, 1878 but found no opportunity to pursue the idea as his business was machine tools.
