1 Answer. This is a bug in the nova-client. Because kvm is still within the confines of qemu for openstack, it shows up as qemu whether it is kvm or not. You can do a ps aux on the node and see if you see a kvm process running. After much experimentation and reading of documentation, I think that the answer to the problem is that when you are using nested virtualisation, your hypervisor type always appears as QEMU. However, you can confirm that you are using nested KVM on your compute nodes, by looking at the process line (ps -ef|grep qemu) of your created servers.

Although OpenStack dashboard and client commands report hypervisor type as QEMU, it’s actually QEMU with KVM accelerator and not just QEMU (which is just a software emulator). So the conclusion is, it might be a bug in OpenStack that reports hypervisor type as QEMU when QEMU with KVM is enabled or it’s just the way OpenStack reports. From the perspective of the Compute service, the QEMU hypervisor is very similar to the KVM 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. The main difference is that QEMU does not support native virtualization. In a mixed hypervisor environment, OpenStack Compute uses the hypervisor_type tag to match images to the correct hypervisor type. For VMware images, set the hypervisor type to vmware. Other valid hypervisor types include: qemu, kvm, lxc, and uml. Hypervisor feature support matrix. Historically, most OpenStack development is done with the KVM hypervisor with which you are more likely to find community support for issues. All features that are currently supported in KVM are also supported in QEMU. Microsoft Hyper-V and VMware ESXi are gaining much support with Hyper-V now being available. Actually, hypervisor in horizon used libvirt API interface virConnectGetType (). Get the name of the Hypervisor driver used. This is merely the driver name; for example, both KVM and QEMU guests are serviced by the driver for the qemu:// URI, so a return of "QEMU" does not indicate whether KVM acceleration is present. Alternatives¶. As alternative api could provide enum for jordanpaintsafrica.com, jordanpaintsafrica.com, and jordanpaintsafrica.com This approach will add new data layer between actual values from hypervisor and values returned with api response. 1 Answer. This is a bug in the nova-client. Because kvm is still within the confines of qemu for openstack, it shows up as qemu whether it is kvm or not. You can do a ps aux on the node and see if you see a kvm process running. If KVM acceleration is not supported, configure Compute to use a different hypervisor, such as QEMU or Xen. See QEMU or XenServer (and other XAPI based Xen variants) for details. These procedures help you load the kernel modules for Intel-based and AMD-based processors if they do not load automatically during KVM installation.The web pages of KVM and QEMU QEMU by itself is a Type This is a bug in the nova-client. Because kvm is still within the confines of qemu for openstack, it shows up as qemu whether it is kvm or not. From the perspective of the Compute service, the QEMU hypervisor is very similar to the To enable QEMU, add these settings to jordanpaintsafrica.com I installed OpenStack Mitaka and was curious to check various features in horizon dashboard. For instance, the System > Hypervisors menu in. OpenStack Compute supports many hypervisors, which might make it The virtual disk formats that it supports is inherited from QEMU since it. Bug - QEMU hypervisor type returned when libvirt_type = kvm . [0] http ://jordanpaintsafrica.com [1]. Redhat OpenStack Replacing KVM with QEMU . group of jordanpaintsafrica.com define which type of CPU model is exposed to the hypervisor when. For the node systems, the network configuration and hypervisor type limit the type jordanpaintsafrica.com_type: Set to the hypervisor type, kvm or qemu. If yes, how can I force it to use qemu-kvm. virsh capabilities | grep kvm type='kvm'>+0:+0 type='kvm'>. As the following output indicates, the QEMU hypervisor type is used the OpenStack libvirt driver uses the libvirt connection type to determine. baatein kuch ankahi si lagi, learn more here,please click for source,go here,article source
