Some month ago I upgraded from Workstation Pro 14 to 17 on a Linux host (Debian 10).
At the time of upgrade I used kernel 4.20.17, and everything was running fine.
Then I tried with a 5.15 kernel (also a 5.10, same outcome), and soon I noticed guest slowing down. With casual occurring, but enough often to be annoying (3-4 times per hour). Lags of 10-15 seconds, guest totally unresponsive. No mouse click nor key press.
When guest was lagging, host was ok and responded as usual.
Since I still have 4.20.17, I did many test and can confirm: 4 is ok, 5 lags.
Since I knew that 5 introduced some mitigation for security issues, I tried disable one of them with tsx=on on boot line.
And this way also 5 works without lags.
Has anyone experienced something similar?
