Vmware

Background: The business system, running in Windows version, is deployed locally and consumes approximately 5% of CPU resources. The Linux version of the business system, deployed within a VMware-installed CentOS8 environment, exhibits abnormal resource consumption.

Problem Description

• Host Machine: Windows 10 Enterprise
• VMware: 17.5
• Virtual Machine: CentOS8 The virtual machine resource allocation is 4C8GB, running the business system. The business system is deployed in the Linux system within the virtual machine, and the internal top command observes system resource usage. CPU utilization is not high, while the external Windows system’s Task Manager shows very high CPU resource consumption. Examining processes reveals that the VMware process consumes a large amount of CPU resources.

When installing a development system with VMware virtual machines, it’s generally recommended to allocate extra disk space. Over time, the local disk space consumed by the VM will far exceed the actual size of its files.

Scenario Description

The df -h command revealed that the current machine was using 60GB of disk space, and after deleting all snapshots and clone images, the local virtual machine still occupied significantly more than 60GB, further straining the already limited hard drive.
