Use Hyper-V Enlightenments to Increase KVM VM Performance/Densit
收藏 0下载 0
Hyper-V designed a set of ‘enlightenments’ to reduce virtualization overhead. Some of the enlightenments has been implemented in KVM so KVM VM can also benefit from it. Recently Hyper-V added some more enlightenments for the VM-based so-called ‘Hyper-V containers’. However, till now these enlightenments are only available on Hyper-V and Windows. In this talk Chao will present we can implement the same enlightenments in KVM and the cooperative change in Linux, so not only Windows but also Linux can take advantages of these enlightenments when running on top of KVM. Especially, we can achieve similar effect for VM-based Linux container (e.g. increase the performance/density for Kata Containers).
