Using KVM.

KVM, Cinder with iSCSI over 10 gigabit network.

Hi, I created a VM using horizon. I picked source as image and I set a volume size of 120GB.

When the VM runs the disk it is visible as /dev/vda and this disk is created on block storage correct?

So when this instance is running on the computer node, if it's a single disk, which part of it is running on the compute and which part is on the block storage? Or in this case it's all running on block storage?

But when reads/writes happen on the VM on the compute node are they not cached locally first and then written to the Cinder block storage?

Update 2018/11/21: Using KVM, Cinder with iSCSI on 10 Gigabit

Currently my network is at the office is setup with private ips of 10.0.0.xxx IPs.

I installed devstack on a 32 core server machine for testing. That machine is 10.0.0.123 all the openstack service are bound to that I.P

My network admin has alowed me to run instances on 10.0.0.22.xxx ranges. How do I change that? Right now I have instances create don 10.0.0.2 and 10.0.0.3 and can't access them....

I think brtfs on OpenSuse was causing plenty off issues. Anyways I installed devstack on Ubuntu 12 and it seems to be working fine...

It was but still wasn't connecting anyway I gave up on it for now...

Followed all the steps until now for OpenSuse 13.1 Everything seems to have installed right but having problems starting the network services. Btw installing everything on a single box for proof of concept.

But when try to start a network service using:

nova network-create vmnet --fixed-range-v4=10.0.0.0/24 --bridge-interface=br100 --multi-host=True

Here is the nova.log

I'm at the endpoint registration for the compute node and the instructions state to run:

keystone endpoint-create \ --service-id=$(keystone service-list | awk '/ compute / {print $2}') \ --publicurl=http://controller:8774/v2/%(tenant_id)s \ --internalurl=http://controller:8774/v2/%(tenant_id)s \ --adminurl=http://controller:8774/v2/%(tenant_id)s

The output of the command is...

+-------------+-----------------------------------------+
|   Property  |                  Value                  |
+-------------+-----------------------------------------+
|   adminurl  | http://controller:8774/v2/%(tenant_id)s |
|      id     |     ca1a13483f5a4159a7cb2b84b89704ad    |
| internalurl | http://controller:8774/v2/%(tenant_id)s |
|  publicurl  | http://controller:8774/v2/%(tenant_id)s |
|    region   |                regionOne                |
|  service_id |     cfd20998eda04692bac6013c22c4b214    |
+-------------+-----------------------------------------+

Is tenant_id suposed to be replaced with something or is that how it is expected?
