简述由于项目需求，需调研目前所有的windows 10激活方式成本及其法律风险，现将调研内容整理至本文章，本文主要介绍目前各种常见的windows 10激活方式对企业用户的风险及成本评估。微软不追究个人用户的盗版使用，所以个人用户不在本次调研范围内，个人用户可随意使用本文中的各种激活方式。 永久激活方案方案介绍官方渠道官方渠道报价：1800/套，量大可优惠至1600 ~ 1700 官方license可接受5次硬件变动，同时只能有一套该license激活的系统在运行。硬件变动范围包括但不限于插拔内存条、插拔硬盘、更换主板等操作。 该激活方式不存在法律风险，唯一的不足就是太贵了。在云场景上，虚机需要不断创删，删除后的虚机会消耗license数量，无法回收，所以该方案的成本非常高。 淘宝店铺淘宝/京东搜索windows激活，即可搜到很多可提供windows激活的店铺，激活价格在几块到几百不等。区别在于一次性过期还是可重复安装，根据调研及网络上各企业反馈，该方式激活的windows同样也会收到微软的律师函，及该方式企业使用是存在法律风险的。该方式个人认为是最不值得的一种方式，既花了钱，还不能规 ...

简介This tool enables the use of Geforce and Quadro GPUs with the NVIDIA vGPU graphics virtualization technology. NVIDIA vGPU normally only supports a few datacenter Teslas and professional Quadro GPUs by design, but not consumer graphics cards through a software limitation. This vgpu_unlock tool aims to remove this limitation on Linux based systems, thus enabling most Maxwell, Pascal, Volta (untested), and Turing based GPUs to use the vGPU technology. Ampere support is currently a work in progres ...

简介主要需求是透传主机目录至虚机内部使用，9p virtio可以提供该能力，9p的官方介绍如下： With QEMU’s 9pfs you can create virtual filesystem devices (virtio-9p-device) and expose them to guests, which essentially means that a certain directory on host machine is made directly accessible by a guest OS as a pass-through file system by using the 9P network protocol for communication between host and guest, if desired even accessible, shared by several guests simultaniously. This section details the steps involved in setting up VirtFS (Pla ...

简介QEMU is a generic and open source machine & userspace emulator and virtualizer. QEMU is capable of emulating a complete machine in software without any need for hardware virtualization support. By using dynamic translation, it achieves very good performance. QEMU can also integrate with the Xen and KVM hypervisors to provide emulated hardware while allowing the hypervisor to manage the CPU. With hypervisor support, QEMU can achieve near native performance for CPUs. When QEMU emulates CPUs ...

安装安装依赖环境要装的两个依赖分别是：gcc、kernel-devel，其中需要注意的是，kernel-devel的版本需要与当前内核的版本一致，不然后面会出现找不到文件的情况。 1）查看我的内核版本： 12[root@k104 vGPU]# uname -r3.10.0-1127.el7.x86_64 2）查看一下可以安装的版本，安装对应内核版本： 12[root@k104 vGPU]# yum list | grep kernel-develkernel-devel.x86_64 3.10.0-1127.el7 @/kernel-devel-3.10.0-1127.el7.x86_64 3）安装依赖 1yum install kernel-devel-$(uname -r) gcc dkms -y 屏蔽系统自带的nouveau（重启生效）123456789101112echo "blacklist nouveau" >> /lib/modprobe.d/dist-blackl ...

简介目前虚拟机环境检测有两个金标准，分别是Al-khaser和Pafish。这两个开源项目几乎一网打尽了所有公开常见的VM检测技术。 国外SANS安全组织的研究人员总结出当前各种虚拟机检测手段不外乎以下四类：● 搜索虚拟环境中的进程，文件系统，注册表；● 搜索虚拟环境中的内存● 搜索虚拟环境中的特定虚拟硬件● 搜索虚拟环境中的特定处理器指令和功能 Al-khaserGithub：https://github.com/LordNoteworthy/al-khaser PafishGithub：https://github.com/a0rtega/pafish 12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364656667686970717273747576777879808182838485868788899091929394959697* Pafish (Paranoid Fi ...
