ya man I wouldn't just restart them I'd delete them and recreate them. I don't think I notice this happening on my machine. I have noticed that xentop shows cpu more accurately though then qubes manager in the past. it will show cpu usage qubes manager doesn't show. But I would still see something happening qubes manager at least. And I don't notice anything weird on idle vms. But I always shut down more trusted ones that have net access just in case they get attacked form other vms. I have noticed, when first started using qubes, that sometimes when an appvm is open it will check for updates. Or that updates won't be checked until you open up an appvm that use that template, but I don't know if thats changed since earlier Qubes versions. I never dug into what process, just correlated the cpu activity with the network activity that would go at the same time on sys-net. Its too hard for me to monitor so many vms on a polylithic system like Qubes. So at first sign of anomaly I just delete the vm so much easier. I mean unless I was experimenting I really don't give a crap whats causing something at this point in my life. Possible malicious? ok wipe it. Qubes makes it easy. If it keeps happening then you need to find out whats going on. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
