Virsh Provider

You can provision virsh virtual machines (VMs) to work with the ICE ClusterWare ™ platform. Complete the required configuration steps to set up a virsh provider, then you can provision VMs and they will function like regular ClusterWare compute nodes.

Configure virsh Provider

1. On the virsh host, add /opt/scyld/clusterware/.ssh/id_rsa.clusterware.pub to authorized_keys.

2. Create the virsh provider in ClusterWare:

    cw-clusterctl providers mk name=<name> type=virsh spec='{
       # interfaces on the hypervisor
       "interfaces": [
          "<bridge name>=<IP>",
          "<bridge2 name>=<IP>"
          ],
          # (OPTIONAL, default=["br0": spec.server])
       # IP for the hypervisor
       "server": "<IP>",
       "server_username": "<username>", (OPTIONAL, default="root")
   }'
   

   For example, the following command creates a virsh provider that attempts to use a remote machine as a virsh host by using SSH to log in as root:

   cw-clusterctl providers mk name=my-provider type=virsh spec='{
      "server": "10.1.1.1"
   }'
   

Work with virsh Virtual Machines

To allocate and attach a VM using the provider name specified during virsh provider creation:

cw-clusterctl providers -i<provider name> alloc --count 1 --attach

To view the VM node status:

cw-nodectl status

To list the provider VMs:

cw-clusterctl providers -i<provider name> resources

To remove the associated compute node and delete the VM:

cw-nodectl rm <node name> --release
