VMShm, a mechanism for accessing POSIX shared memory from QEMU/kvm guests

VMShm is a mechanism that enables qemu virtual machines to access to POSIX shared memory objects created on the host OS. VMShm make it possible to an user space application running in a virtual machine to map up to 1M of a POSIX shared memory object from the host OS. It can be used as … Continue reading VMShm, a mechanism for accessing POSIX shared memory from QEMU/kvm guests →

gVirtuS: the first beta release

We are proud to announce the first beta release of gVirtuS. gVirtuS allows an instanced virtual machine to access GPGPUs in a transparent way, with an overhead slightly greater than a real machine/GPGPU setup. gVirtuS is hypervisor independent, and, even though it currently virtualizes nVIDIA CUDA based GPUs. The software, developed for research applications, is … Continue reading gVirtuS: the first beta release →

VMSocket: a mechanism to expose UNIX Sockets in KVM Virtual Machines

VMSocket is a mechanism to expose UNIX Sockets (sockets in AF_UNIX domain) from the host operating system to the KVM's virtual machines. It provides a really fast communication channel between host and guests os. It can ben used for communication that needs to be fast, such as HPC (High Performance Computing) software solutions and so … Continue reading VMSocket: a mechanism to expose UNIX Sockets in KVM Virtual Machines →
