As far as I remember, there was an idea to kill stubdoms after boot, which would both reduce risk (as stubdoms run in PV) and CPU+memory overhead. I cannot try it right now, because I haven't installed Q4. > If I switch to disposable VMs, I assume the risk would be reduced. You can sort reduce

Hello, I was able to improve battery runtime following the tips from this thread: I've switched all my AppVMs to virt_mode = pv, using: dom0: qvm-prefs --set virt_mode pv In order to monitor my battery runtime and battery discharge rate, I've setup a small monitor in my xfce4-panel: 1)

Another partial workaround, you can change virt_mode from hvm back to pv for trustworthy VMs, like vault, etc... The bug: https://github.com/QubesOS/qubes-issues/issues/2849 For me it amounts to an overhead of 10% x cpu core per hvm, according to xentop. -- You received this message because
