In addition to all the serious possibilities that everyone else already mentioned, you may also want to take a look at the trivial reasons --- maybe the Windows screensaver is configured to activate after 5 min of user inactivity, and starts draining the CPU by drawing 3D intensive stuff on the virtual display (you know --- pipes, swimming fish, whatever). Naturally, it turns itself off as soon as it detects keyboard/mouse activity, i.e. when you start the virt-viewer again, and you never even know it was there. So you may want to take a look at all the screenlocking, screensaving, power saving, etc... settings in Windows, and make sure all that stuff (that doesn't make sense in a virtual machine environment), is turned off and deactivated. Just a thought. ;-) Best, :-) Marko _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
