Last year, Nvidia provides GRID K1 and GRID K2 GPUs for GPU virtualization. One could run multiple VM sharing the same graphic card to render complex applications. It takes the similar solution of SR-IOV but different approach. VMWare utilizes this GPU virtualization on their products and make the GPU performance in VM almost the same performance on bare-metal machine. Even without vGPU, VMWare’s Fusion still has about 90% of bare-metal performance.
Hello there! I’ve been using QEMU for a while. Recently, I updated my ARM image and found that it has some difficulties to make an ARM image and could be an impossible job for those who are not familiar with embedded systems. I decided to write a comprehensive post to share some knowledge and how to build you own ARM image. This post could be very useful for those who want to know how Linux works with minimum requirements (root file system, in short rootfs). I use Vexpress as the target board in the tutorial.
While QEMU has continued to be optimized for KVM to make use of the growing number of cores on modern systems TCG emulation has been stuck running in a single thread. This year there is another push to get a workable solution merged upstream.
It’s been a while since I played around lxc container. Many people still have trouble on building an Ubuntu container on Arch Linux. So I decided to give comprehensive instructions to help you deploy containers.
The following instructions will teach you how to build up and Ubuntu container and setup the internet.
When using a virtual machine, people may dream to have a virtual machine running as fast as the real machine so that playing games on MAC or Linux can be true. While dreaming that, there is a very important concept you need to know, virtualization overhead.
