修改配置解决VMware vSphere最低内存2G的限制
VMware vSphere对硬件的要求比较高，但是对于测试系统来说我们是希望配置要求越低越好，CPU的要求卡死在哪里，必须要64位系统，安装客户机必须要支持VT技术才能安装64位的，这些是没什么好商量的。
但是内存方面VMware vSphere最低2G的内存似乎是高了点，如果达不到这个要求系统是无法启动的，对于测试环境来说可能每台esx服务器只安装一两个客户机不一定用得到这么多内存，因此我们可以通过手动修改VMware vSphere的配置来达到低于2G内存启动VMware vSphere。
如下图所示，当内存少于2G时，VMware vSphere自动中断启动。
修改办法如下：
满足2G内存的情况下启动VMware vSphere，按Alt+F1进入维护模式
输入命令"vi /etc/vmware/init/init.d/vi 00.vmnix"修改VMware vSphere配置
找到“RequiredMemory=2064384”这行配置，将2064384修改你希望的内存大小，保存配置。
关闭系统，修改低于2G的内存数值，重新启动VMware vSphere就可以正常启动了。
As some of you noticed, when you install vSphere(ESX) within a VM you will need at least 2GB to get the installer started. Even when it has finished installing you can’t reduce the memory because the following error will occur:
I couldn’t find a way of pre-adjusting the memory requirements but there’s a way to change this be
havior and to downsize the memory when the installation has finished. Keep in mind this is, as far as I know, not supported… it’s only to be used to run ESX within VMware Workstation for your demo / test environment. I personally use it for running 2 ESX servers and vCenter within VMware Workstation on my 4GB laptop. (That’s what I actually use to create screenshots and prepare blog articles.)
- Install vSphere(ESX) with at least 2 GB memory
- Login to the Service Console and type the following:
vi /etc/vmware/init/init.d/00.vmnix
- Change the following line to the desired value: RequiredMemory=2064384
- Shutdown the virtual machine and change the VMs memory and boot it up!
- Install vSphere(ESXi) with at least 2 GB memory
- Login to the console via the “unsupported” method.
- Edit the file /etc/vmware/esx.conf and add the following line:
/vmkernel/minMemoryCheck = “false”
- Save the file and shutdown ESXi, change the memory and boot it up!
