Host CPU does not scale frequency when KVM guest needs it As for the distribution, I mentioned Ubuntu as problematic because it is. Both on SF and other sites, I keep seeing people reporting KVM related issues that I never manage to reproduce on Fedora or RHEL. Please feel free to disagree, I am not continuing into a flamewar here. |

Host CPU does not scale frequency when KVM guest needs it Nothing to do with live migration actually. The CPU flag set is easily brought to a common denominator by libvirt's CPU model abstraction, but have you actually tried to migrate a production VM between two drastically different CPUs? In quite a few applications, alternating frequencies can cause problems. And with VMs the problem can only grow, because there is no mechanism that would provide a feedback to the CPU controller. |

Host CPU does not scale frequency when KVM guest needs it I don't have any articles handy, but think about what virtualization is for, and how it works. You are planning to utilize an underutilized machine by loading it with VMs. The VMs should be stable and predictable. Do you think a CPU frequency adjustments underneath the VMs will help with that? And talking about best practice, ubuntu as a virt host is not a good idea in my experience |

How do I send a shutdown event to a QEMU guest (OpenBSD)? none of these is a shutdown. system stop with no poweroff and a reboot are not shutdown. Maybe Alt+SysRQ+o will work (it's APM, so I doubt the VM with terminate after stopping everything, but...) the key combination can be sent via the qemu-monitor sendkey routine |

Do I need hardware support for KVM for virtio paravirtualisation wiki.libvirt.org/page/Virtio#Requirements - as you can see KVM is not required. You do need to formulate your questions better though, because "Do I need hardware support for KVM for virtio paravirtualisation" is very KVM specific |

Do I need hardware support for KVM for virtio paravirtualisation what you're talking about is true, but it has nothing to do with kvm. kvm is full virtualization only |
