Whenever I start an Ubuntu Server virtual machine in VMware Workstation Pro, disk usage suddenly jumps and the computer eventually freezes if I keep using it. MySQL also fails to start inside the VM. I have already disabled services such as MySQL, PostgreSQL, and other programs that I do not need running automatically. The host system has 8 GB of RAM, a 7th-generation Intel Core i7 processor, and a 1 TB hard drive. Could limited memory or the mechanical drive be causing the heavy activity and lockups?

MySQL failing to start may be a separate symptom of the VM being under pressure. Check the MySQL service status and its error log inside Ubuntu rather than disabling more host services. Also verify that another database process is not already using MySQL's port and that the VM has enough disk space and memory. If the machine freezes only when the VM is running, monitor host RAM, committed memory, and disk usage to confirm whether swapping is the cause.
The most likely bottleneck is memory and storage, not the processor. With only 8 GB of RAM, the host and virtual machine can quickly run out of usable memory, causing Windows or the VM to swap heavily to the hard drive. That produces very high disk activity and can make the whole system appear frozen. Check how much RAM and how many virtual CPUs the VM is assigned, close other applications, and leave enough memory for the host. Moving the VM and host operating system to an SSD would also make a major difference, although it will not completely solve a RAM shortage.
