Greetings, I recently upgraded from 20.xxx to 26.2.0, and it is a constant battle to keep my VMs up. I do software consulting and generally run between 3 and 5 VMs at a time on an M2 Max with 96GB ram. I use VMs, (mostly linux) to isolate each customer's work to a single machine. My schedule doesn't allow a lot of time to do anything but work to keep up with my customer workload, so I need to determine if I can go back to the last 20.xxx version. Briefly, since upgrading to the latest, I am seeing the following issues: The dreaded 2199 bug, https://simulakrum.com/dreaded2119-bug.html has gone from happening every few weeks/months to every few hours/days VMs sometimes go to 100% CPU on the Mac activity monitor and become unreachable, even by ping, sometimes they come back on their own, and sometimes I have to reset the VM For the heck of it, I tried setting a script to run renice on processes consuming 100% CPU, but it didn't help, likely the high CPU usage is coming from a kernel task I see a lot of watchdog timeouts in the logs, so it seems like CPU starvation might be the culprit, but hard to say. If I had the time, I could dig in, but that is why I pay for parallels. I am happy to help troubleshoot as my time allows, but for now, I would like some advice about reverting the parallels version. Is is possible? Is it easy? Thank you
Today, I was happy to see my VMs survived overnight, however ~5 hours later, the 2199 bug hit. A reboot resulted in the machine coming up still with the far off future date. I had to shutdown and restart to fix that.
