I have a &quot;home lab&quot; ESXi 5.0 host with 16GB RAM and about 8 VM's, two of which are running currently: a Win 7 32-bit with 1.5GB RAM (all reserved) and a Windows Server 2011 64-bit 3 GB RAM (none reserved). <br />
<br />
1. vSphere client reports on the host summary tab having 16 MB RAM but the resource allocation tab for VM's reports only about 13GB available. (See attached.) Why is that? Is there something wrong? Note that the overhead for one VM is 45MB and for the other 90MB for a total of 135MB - nothing approaching the ~3GB difference.<br />
<br />
2. vSphere client reports having 4 x 3.392 MHz = 13.584 MHz of CPU capacity, yet the capacity apparently available to VM's is only 11532 Mhz. (see attached.) Why is that? Is there something wrong with my configuration?<br />

VMware ESXi 5.0 not using all available CPU and RAM?

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
