Here are several flags that you must set on your compute host for a multi host deploy:
- :option:`--vncserver_listen` <https://github.com/openstack/nova#id3> - defaults to 127.0.0.1 This is the address that vncservers will bind, and should be overridden in production deployments as a private address. Applies to libvirt only. For multi-host libvirt deployments this should be set to a host management ip on the same network as the proxies. - :option:`--vncserver_proxyclient_address`<https://github.com/openstack/nova#id5> - defaults to 127.0.0.1 This is the address of the compute host that nova will instruct proxies to use when connecting to instance vncservers. For all-in-one xen server domU deployments this can be set to 169.254.0.1. For multi-host xen server domU deployments this can be set to a dom0 management ip on the same network as the proxies. For multi-host libvirt deployments this can be set to a host management ip on the same network as the proxies. - :option:`--novncproxy_base_url=[base url for client connections]`<https://github.com/openstack/nova#id7> - this is the public base url to which clients will connect. "?token=abc" will be added to this url for the purposes of auth. When using the system as described in this document, an appropriate value is " http://$SERVICE_HOST:6080/vnc_auto.html"; where SERVICE_HOST is a public hostname. Suppose you have 2 servers, APISERVER and COMPUTESERVER: APISERVER: public hostname = my.server.com management ip = 192.168.1.1 public ip = 172.24.4.1 COMPUTESERVER: management ip = 192.168.1.2 Your nova.conf con COMPUTESERVER would need the following flags: novncproxy_base_url=http://my.server.com:6080/vnc_auto.html or novncproxy_base_url=http://172.24.4.1:6080/vnc_auto.html vncserver_proxyclient_address=192.168.1.2 vncserver_listen=192.168.1.2 Note that novncproxy_base_url references a public ip or hostname (so clients can connect), while the other flags use private ips.
