Vagrant - 如何检测Windows主机RAM和CPU

Question

我希望我的 vagrantfile 根据主机规范自动设置 CPU 和 RAM。

我找到了这个片段:

 config.vm.provider "virtualbox" do |v|
      host = RbConfig::CONFIG['host_os']
      # Give VM 1/4 system memory & access to all cpu cores on the host
      if host =~ /darwin/
        cpus = `sysctl -n hw.ncpu`.to_i
        # sysctl returns Bytes and we need to convert to MB
        mem = `sysctl -n hw.memsize`.to_i / 1024 / 1024 / 4
      elsif host =~ /linux/
        cpus = `nproc`.to_i
        # meminfo shows KB and we need to convert to MB
        mem = `grep 'MemTotal' /proc/meminfo | sed -e 's/MemTotal://' -e 's/ kB//'`.to_i / 1024 / 4
      else # sorry Windows folks, I can't help you
        cpus = 2
        mem = 1024
      end

      v.customize ["modifyvm", :id, "--memory", mem]
      v.customize ["modifyvm", :id, "--cpus", cpus]
end

但是它不适用于 Windows(它设置默认值 2 和 1024)。

有人知道如何做到这一点吗？

我设法将其理解为我们的并将其集成到 Git repo 中.

代码:

cpus = `wmic cpu get NumberOfCores`.split("\n")[2].to_i
mem = `wmic OS get TotalVisibleMemorySize`.split("\n")[2].to_i / 1024 /4
