[libvirt-users] security BPC

HI! Disclaimer: I'm a libvirt beginner using it for managing virtual machines based on qemu-kvm. Is there any documentation describing how to harden libvirt/qemu-kvm installations? Escpecially how to improve isolation of VMs: - secure time sync (with or without ntpd?) - random number generation - running VMs as different host OS users I do not need general OS hardening advice. Ciao, Michael.
