Does your VM freeze periodically? Then this article is for you. At Bobcares, with our Server Management Service, we can handle your VM issues.

VM Freezes Periodically: How To Fix It?

Similar to a real server, a virtual machine can become unresponsive, freeze, or hang for a variety of reasons. Some of the reasons include:

• Cannot access VMs across a network.
• Virtual machines could signal a bad situation.
• The VM will not support vCenter Server virtual machine console screen, RDP, and other connection methods.
• VM will not create VNetwork and disk traffic.
• The presence of VMware tools inside the guest disqualifies any potential networking or MKS (Mouse, Keyboard, Screen) problems.

VM Freezes Periodically: Troubleshooting

1. Allocating Resources: Verify the virtual machine’s resource allocation, including its use of CPU, memory, and disk space. Make that the resources supplied are adequate for the workload being run on the VM. The VM may freeze or become unresponsive if it is resource-starved. If there is a need for more resources, take that into account.

2. Ensuring Enough Resources: Make sure there are enough resources on the host system that is powering the virtual machine. The host’s lack of resources can also affect the VM’s performance. To make sure the host system is not overwhelmed, keep an eye on its CPU, memory, and disk usage.

3. Set up Hypervisor: Examine the hypervisor’s configuration options (such as VMware, VirtualBox, and Hyper-V). Verify any specific parameters that might have an effect on the stability or performance of the VM. If necessary, modify parameters for the I/O scheduler, CPU mode, memory allocation, and virtualization extensions.

4. Ensuring Up-to-date OS: Make that the virtual machine’s guest operating system has the most recent patches and updates installed. Compatibility or stability issues may result from outdated software or drivers. Update the operating system, then install any virtualization platform-specific driver updates that are available.

5. Examining System Logs: Look through the virtual machine’s and the host system’s system logs for any error or warning messages that might point to the cause of the freezing problem. Search for any trends or particular error codes that could point to the issue.
