Docker For Mac Vs Parrells4/18/2021
After reading what a hypervisor does it adds fuel to my own hypothesis regarding why the processes are acting so strange in the VM.Its running in user space, and doesnt require developers to write kernel extensions to use.
Personally, Ive had erratic stability and performance issues that I can roughly tie to Parallels. Im going to use it in Apple Hypervisor for a while and see how that goes. Its quite possible that Parallels can create a Mac App Store version of Parallels, and keep not all but most of its advantages. I know that people having issues with there Vms not running or booting into a black screen after the parallels desktop 12 update, changing the hypervisor to apple will usually solve this right away and everything goes back to working as it should. It seems to me that the apple hypervisor is at least decently stable. I also did some benchmarking with each hypervisor enabled and didnt notice a difference in the test result. I am using an SSD with native drive access. I was using Ubuntu inside Parallels running some memory-demanding applications. From my observations, Parallel Hypervisor seems to be very extravagant in claiming memories, causing a large chunk of data being put into hosts cache files. Surprisingly, the performance is quite satisfying, and memory pressure is green all the time. Last week I decided to start doing more testing in other OSs. Though I gave the VM 8 gb of RAM, it appears to only use that which it needs. I turned coherence mode off, and the problems seem to have gotten better (but not great and I love coherence mode). Then while browsing the settings I found the hypervisor setting. I can run in coherence mode with the Apple hypervisor and my Mac side CPU usage is less than half, fans dont come on etc. Considered getting a refund for purchasing Parallels, but thought Id see if I could fix the problem first. Docker Vs Parrells Software In TheI switched to Apple hypervisor, and my problem disappeared, no more random reboots Its been stable and memory utilisation is improved which is a bonus Message to Parallels: You are developing software in the virtualisation space. Processes that have never caused issues are now flagged as sucking up 80-400 of the CPU (yes, 400, it depends on if I view the CPU usage from within or outside of the VM) and freezing the entire VM. They run rampant and the end result is that the entire Windows UI freezes. From what Ive read above, changing the hypervisor seems to mitigate the problem.
