Hi Experts,
I use VMware Workstation on my Zorin OS 16 Pro machine.
(Please don't suggest another hypervisor. I need the virtual TPM in VMware to run the vm for work. None of the other hypervisors will work.)
Is there a way to implement a fix in Zorin going forward for the following issue: kcompacd0 using 100% CPU with VMware Workstation 16 - Unix & Linux Stack Exchange
Additional Notes
This is the solution for me on Zorin 16 Pro:
Shut down the VM
Open the <vm_name>.vmx file for the VM using a text editor
Add the following lines to the end of the vmx file:
# Fix problem where vmware battles with kcompactd0.
vm.compaction_proactiveness=0
Save file and restart VM
If you upgrade to VMware Workstation Pro 16.2.1, make sure you upgrade your VMs to 16.2 and reboot your machine before testing. I did not reboot after upgrading and the issue persisted until the reboot.
