许久没关注过VDI了，一直坚持的观点就是协议要牛逼，否则就是渣。
VOI、IDV都不太行，GPU本机显示还是有些小问题，要么远程的，要么就没有虚拟化。
直到离开VDI行业三年多后发现还有这个炫酷的东西满足了当时我对单机虚拟化的期望，https://looking-glass.io，虚拟机与宿主机可以共享显示（iGPU），或者独占显示但是键鼠仍然与原生一致。
PS：ArchLinux社区万岁，这是原文。

NVMe in the Cloud(ZStack)
NVMe作为新的存储协议，更能将新的存储介质的性能发挥出来，与此同时，与SCSI存储对等的NVMeOverFabric和NVMeOverTCP也已经开始在数据中心中崭露头角。
传统云平台中的对这些存储设备的使用是没有任何问题的，但是在不改变存储对接架构的情况下发挥出其原生性能则是一个挑战。
关于瓶颈的问题，我们可以从不同的存储对接路径去分析。
当然，不同于公有云的机器完全自定义，硬件自己随便攒，私有云为… Read more...
