Hi everybody , my english is pool , so i can speak chinese

Environment Ubuntu 14.4 LTS

Version : Liberty

Quesion :

  1. how to add Xen hypervisor using libvirt ,not use devstack ?

    I look a lot of info online, almost using devstack.

    I don't use devstack , I follow Openstack office docs to install .(ubuntu 14.04)

    Please give me advise to achive add Xen.

    Default "KVM" change "Xen" , I need Xen environment .

    TARGET : Enable new instance with Xen hypervisor .

    如何透過 libvirt 加入Xen hypervisor ?

    查閱過很多線上的資訊,大多都使用 Devstack 這 script 來安裝Openstack , 同時也用 Devstack 加入Xen

    我不會使用 Devstack 安裝 Openstack ,更不會使用它來加入Xen

    我是使用Openstack官方提供的 Docs 來架設 Openstack (Ubuntu 14.04 LTS)

    請各位高手給點建議或者能否提供教學,還是能提供相關連結網站來幫助我

    因實驗需要,需將原本預設的 "KVM" 換成 "Xen" 環境

    目標 : 能夠啟動新的VM在Xen的環境下


  1. If add Xen hypervisor , can both "KVM" and "Xen" in two compute node runnung ?

    Now , Openstack have support multiple hypervisor running ?

    如果可以成功架設 Xen ,是否可以同時存在"KVM" 和 "Xen" 在各自的 compute node

    現今的Openstack 是否能支持同時執行多個 hypervisor 的環境

    跑不同hypervisor的VM

    please help me.

    THANKS.

    請各位幫忙

    感激

So, Controller running neutron-server , works via Libvirt with Xen Hypervisor on Compute Node
Am I correct ? and you don't use XENAPI.

See http://docs.openstack.org/mitaka/conf...
Known issues

Networking: Xen via libvirt is currently only supported with nova-network. Fixes for a number of bugs are currently being worked on to make sure that Xen via libvirt will also work with OpenStack Networking (neutron).

Question :- If add Xen hypervisor , can both "KVM" and "Xen" in two compute node runnung
Try in different AZ each compute node

what is Known issues of Networking .... ??

I detail look , but I don't understand what mean.

what help to me ?

It would work only with Legal Nova Network and won't work with Neutron. For myself (RDO deployments) this feature in meantime doesn't make any sense. RH deprecated Nova Networking in Havana Release. You do can work with Xen , however not via Libvirt. Just do some Googling
