When Trying to Use Xen Hypervisor on OpenStack, Virtual machines can not get ip


Gökhan ISIK

Question

Hi ,

I am trying to test hypervisors which OpenStack supported. So I installed 1 controller node , 1 xen compute node and 1 kvm compute node.

I installed OpenStack Pike version. My kvm compute node works properly but I have problem about xen compute node.

ı installed xen server 7.0 version to my server and on domU I created centos 7 virtual machine and ı installed nova-compute on it. For installing Openstack on xen I followed  https://openstack-xenserver.readthedocs.io/en/latest/ guide. When I tried creating virtual machine , virtual machine is created but it has no ip. It didn't get any ip.

I have no experince on xen server and ı don't know how ı can solve this problem. I looked at logs but I didn't see any errors. I need your help. 

I doubt of my neutron config. ı have 2 nics and one for management network and 1 for public network. These are my nics on dom0[https://imgur.com/a/IrdLoCn]. these are my nics on domU [https://imgur.com/a/5RliHa7]. 

I am sending my ifconfig output on dom0[http://paste.openstack.org/show/750146/]  and domU[http://paste.openstack.org/show/750147/].

I am also sending my openvswitch_agent.ini file[ http://paste.openstack.org/show/750148/ ].

ı need your help about creating xen server OpenStack Compute node.
