Hello,
I am trying to deploy OpenStack 10 using OpenStack Platform Director 10.
I am using a bare-metal server with RedHat 7.4, on which I have created 3 VMs:
1st VM is the undercloud node, 2nd VM is the overcloud controller node and the
3rd VM is the overcloud compute node.
The bare-metal server I am using is also my KVM hypervisor for the overcloud.
The bare-metal server has 2 interfaces: an external interface used in
instackenv.json for registering the overcloud nodes and a provisioning interface
which will be used for provisioning the overcloud nodes.
I'm not sure I understand how the bare metal server's interfaces are related
here. What you need is two *virtual* networks: one joining the undercloud and
the host for controlling the undercloud, the other joining the undercloud and
all overcloud nodes for provisioning. You may add more, of course, if you need
them. In your pm_addr field you have to use the IP address of the host node in
the first virtual network.
My 1st question is: Is it mandatory that the KVM hypervisor for the overcloud
VMs and the undercloud are the same machine?
It's not, but making DHCP work across hypervisors may be a difficult task.
As you can see, in my case the undercloud VM and the KVM hypervisor are
different machines.
I saw a blog post which used a topology similar to mine:
https://keithtenzer.com/2017/04/20/red-hat-openstack-platform-10-newton-i...
The error I am getting while running:
openstack baremetal import -- json ~/.instackenv.json
is in ironic_conductor.log: Failed to validate power driver interface for node
<uuid>. Error: SSH connection cannot be established: Failed to establish SSH
connection to host <kvm_hypervisor_external_ip_address >
First of all, put your private key somewhere and make sure the following works
*from the undercloud* without asking for any passwords:
ssh -i <path to private key> <hypervisor ip address>
Hope that helps,
Dmitry
I have created the instackenv.json file which looks similar to this:
"arch": "x86_64",
"host-ip": "<kvm_hypervisor_external_ip_address>",
"power_manager":
"nova.virt.baremetal.virtual_power_driver.VirtualPowerManager",
"ssh-user": "stack",
"ssh-key": "$(cat ~/.ssh/id_rsa)",
"nodes": [
{
"mac": [
"<overcloud_controller_provisioning_interface_mac_address>"
],
"name": "overcloud-controller",
"capabilities" : "profile:control",
"cpu": "4",
"memory": "6000",
"disk": "50",
"arch": "x86_64",
"pm_user": "stack",
"pm_addr": "<kvm_hypervisor_external_ip_address>",
"pm_password": "$(cat ~/.ssh/id_rsa)",
"pm_type": "pxe_ssh"
}
,
{
"mac": [
"<overcloud_compute_provisioning_interface_mac_address>"
],
"name": "overcloud-compute",
"capabilities" : "profile:compute",
"cpu": "4",
"memory": "6000",
"disk": "50",
"arch": "x86_64",
"pm_user": "stack",
"pm_addr": "<kvm_hypervisor_external_ip_address>",
"pm_password": "$(cat ~/.ssh/id_rsa)",
"pm_type": "pxe_ssh"
}
]
}
Do you have any idea what might have gone wrong and how can I progress with my
overcloud node registration?
Thanks,
Anda
