So I take it that --> "You can't have them both at once, at the same time" which turns out to be really unfortunate for my tasks. ERGO: what I'm going to try is: o) delete all static kvm stuff in the kernel .config / rebuild / reboot o) un-merge app-emulation/kvm-84 "without modules" o) emerge vmware-workstation o) emerge app-emulation/kvm-84 "with modules" o) don't auto-load kvm and kvm-[intel|amd] o) !! EITHER start vmware o) !! OR load / start KVM, o) !! thus manually avoiding those threatening kernel lockups. Are there any plans @ KVM to change the (*) behavior in the future, e.g. switching in and out of root mode each time so as to not conflict with other virtualization software?
