The qemu hypervisor supports the following virtual machine image. Openstack is also a linux distribution, so the marriage of openstack with kvm makes sense. Hypervisors and openstack work handinhand to create, manage, and monitor virtual machines. The openstack server migrate command is used to migrate an openstack instance from one compute host to another. The key performance factors in the nfv use case are throughput, latency and jitter. The openstack map gives you an at a glance view of the openstack landscape to see where those services fit and how they can work together. The difference lies in the underlying hypervisor used by libvirt. Also integrated are the guest initialization tools cloudbaseinit, security updates, proper performance and security configurations as well as the final sysprep.

Flexibility is power the amount of flexibility openstack has to offer from a design and deployment aspect is the power all infrastructure admins want and need. According to a recent openstack user survey, the most widely adopted hypervisor in the openstack community is kvm. The virtual disk formats that it supports is inherited from qemu since it uses a modified. Kvm is perhaps the most famous open source hypervisor, and for openstack, kvm is used extensively. For sake of optimal performance, it will default to using virtio for both disk and nic models. The only openstack services required on a hyperv node are novacompute and neutronhypervagent. Xen is a virtualmachine monitor providing services that allow multiple computer operating systems to execut. For example, you can use vendorspecific network technologies like open vswitch, cisco nexus1. Most of the logics at the openstack layer are the same when using either hypervisor. This is a common task when compute node has issues or maintenance has to be done on it.
This extension applies to the nova api and exists for the purpose of defining additional hypervisor location information needed to support making placement decisions with respect to a more detailed datacenter model than has been possible heretofore. Supports kvm, several public cloud providers, openstack, docker and bare metal servers. From the perspective of the compute service, the qemu hypervisor is very similar to the kvm hypervisor. Sharklinux sharklinux is a 64 bit os that specializes in virtualization and features a custom matexfce desktop.

I installed openstack mitaka and was curious to check various features in horizon dashboard. First, all of the openstack services make use of restful apis that allow you to plug and play your own backend technologies.
Also important is the hypervisor s feature parity, documentation, and the level of community experience. If you specify qemu as the hypervisor, you can run your vm in emulation mode, which was qemu originally designed for. All features that are currently supported in kvm are also supported in qemu. You must install the novacompute service in a paravirtualized vm. Mostly it is not used as emulator but as virtualizer in collaboration with kvm kernel components. Applications in the virtual machines can thus use any gpu in the physical machine to. Openstack compute nova supports many hypervisors to various degrees, including. If we create vm with usb device but no usb controller, the usb device will default be attached to the default uhci controller, but speed may mismatch. Xen using libvirt xen project hypervisor using libvirt as management.
Openstacks role in the life of a hypervisor trilio. The main difference is that qemu does not support native virtualization. Update 12152016 follow same guide line lines to get packstack working on centos 7. Qemu kvm this hypervisor is a virtualization layer in the kernelbased virtual machine kvm. It blends perfectly well with any new or existing cloud deployment, interoperating with other hypervisors like kvm, vmware vsphere esxi or xenserver. It is possible to move an instance from one compute host to another in openstack. Where are hypervisors and how they work in openstack. Explain what hypervisor is and what type of hypervisor. Why does openstack report hypervisor type as qemu when. I would like to know if the problem is related to this specific vmware environment, because the image is for kvm and not vmware virtualization.
In that case it utilizes the virtualization technology of the hardware to virtualize guests. Note that qemu is used for both qemu and kvm hypervisor types. Red hat openstack platform 10 director configures the compute nodes to enforce resource partitioning and fine tuning to achieve line rate performance for the guest vnfs. Now, your multi hypervisor openstack environment is all set. However, you can use computefilter and imagepropertiesfilter to schedule different hypervisors within the same installation. You remember those old nokia phones having thick pin charger.
Vocale is an extension to the qemu hypervisor that emulates the cuda library in qemu s virtual machines. Hi friend, i have installed liberty on 3 node ubuntu. Today i received an email from customer, question us, what hypervisor usually use openstack, kvm, xen or vmware. The red hat customer portal delivers the knowledge, expertise, and guidance available through your red hat subscription. We plan to release images for additional hypervisors as well quite soon xenserver xcp and esxi vsphere. Win2012 boot error on openstack in vmware env cloudbase. How to migrate openstack instance from one compute host to. This can happen if you load the kvm module before you install novacompute. Consequently, the openstack community embraced kvm and turned it into the most highly tested and feature rich hypervisor to use in an openstack cloud. Regarding the resources needed for this host you have to consider that hyperv will require 16 gb 20 gb of disk space for the os itself, including updates. The results of this can be seen from the capabilities xml output. I successfully install openstack on real hardware with vitalization enabled, then i configure it to use kvm. This filter checks that the aggregate metadata satisfies any extra specifications associated with the instance type.
The qemu hypervisor supports the following virtual machine image formats. In this scenario, openstack is used as the control plane to manage a multi hypervisor cloud, running both vsphere and an alternate hypervisor such as kvm or xen. Windows instances work out of the box on hyperv, without the need of external drivers and with the benefits of microsoft support. Qemu is a type 2 hypervisor that runs within user space and performs virtual hardware emulation, whereas kvm is a type 1 hypervisor that runs in kernel space, that allows a user space program access to the hardware virtualization features of various processors.
Nameurl, description, ui type, last updated, notes, license. For the smm system management mode feature, only the qemu q35 machine type is supported. Our official openstack windows server evaluation images got updated to the freshly released 2012 r2 version just in time for the hong kong summit full support for openstack havana is included for kvm and hyperv.

We have documentation to help get started, mailing lists where you can connect with other users, and communitysupported packages of the most uptodate openstack releases available for download. Qemu is a machine emulator that can run operating systems and programs for one machine on a different machine. After configuration of compute node i could see hypervisor list is empty please find the below details as per my observation and suggest me for any possible solution on this. I read a lot about that but i cannot find a solution which fits for me.
Microsoft hyperv is an amazing compute option for openstack. Use your open source software to manage your open source hypervisor. Both are controlled through libvirt, both support the same feature set, and all virtual machine images that are compatible with kvm are also compatible with qemu. It is a hypervisor manager intended to remove the worry over hardware and its management. Openstack compute supports many hypervisors, which might make it difficult for you to choose one.
