![]() ![]() Workstation 14 didn't run on older Core-I processors of Intels first CPU generation, introduced 2008. German site has published the article VMware Workstation 14 braucht jüngere Prozessoren, dealing with the same topic. 64-bit CPU from Intel Sandy Bridge or from the AMD bulldozer generation is expected. ![]() While VMware Player 14 runs on older CPUs, the hardware requirements for Workstation 14 has been raised. This requirements may be found under System requirements in VMware's web shop. Now 64-bit processor of the generation "Bulldozer" or better. AMD: Previously 64 FX dual-core processor or equivalent.Now a 64-bit processor of the generation "Sandy Bridge" or better. Intel: Previously Core 2 Duo processor or equivalent.There I saw the changed requirements for Workstation 14: I read a few days ago the announcement of VMware Player 14 and VMware Workstation 14 on a German site here. This feature adds a unified advanced firmware interface (UEFI) Secure Boot module and a virtual Trusted Platform module to ensure the highest levels of operating system security. Within my German article I mentioned, that Workstation 14 Pro provides enhanced support for Virtual Based Security (VBS) in Windows 10 and Windows Server 2016. VMware Workstation and Player allows to virtualize several operating systems as guest in virtual machines on a Windows or Linux host. Now both products has been released end of September. CPU scheduling deep dive.It has been announced in mid of August 2017 (see my German article VMware Workstation 14 Pro und Workstation 14 Player), that VMware Workstation 14 Pro and VMware Player 14 for Windows and Linux will be available in October 2017. It's more complicated than this, but I'm trying to keep it high level. The more vCPUs you give it, the more difficult (slower) it will be to schedule. When you give a vm x number of vCPUs, the VM will need to wait till that many cores are free on the CPU to do 'work'. The way a hosted hypervisor (VMware Workstation) handles guest CPU usage is through a CPU scheduler. You'll may want to start with no more than 2vCPUs, checkout top to see how utilized the application is under load, and then make an assessment for more/less vCPUs. Start with 2GB and see how the app behaves. If you are seeing any swap memory used (paging to disk), you may want to increase the RAM. If you see a low % of RAM being used, you can probably reduce what you're giving the VM. You can also install htop which you may find friendlier than top. Inside your VM (CentOS) you can run top to see how much memory and cpu % is being used. "Correctly" is subjective based upon your expectations. Ideally, you want to provide the VM with the minimum amount of resources the app requires to run correctly. This is referred to as 'right-sizing' a vm, and it is dependent on the application workload that will run inside it. ![]()
