    Running Debian 13 with Parallels 20. I noticed in syslog that KASLR is not initialized ... "

    Still have this specific problem at boot as decribed by zslg01. At shut down the VM also waits for 1 min and 30 secs for the non-responsive Parallels Tools service to close down and then it forces it to stop.
    I have an up-to-date Parallels 26, masOS Tahoe, M2 Pro MacBookPro.
