Best regards, Claudiu Belu 2017-07-29 19:02:44 +0300 answered a question cinder volume attach error in ocata. Hello, It would be a lot easier to understand the logs you've provided if they would be included in a paste, like: http://paste.openstack.org/ or any other paste. From what I can understand, 2 errors occured: the first one while connecting the iSCSI volume, and the second one while formatting the exception message. In order to better understand the issue, a few more bits of information would be useful: What kind of iSCSI backend are you using? What locale do you use in this environment? Best regards, Claudiu Belu 2017-06-14 17:20:20 +0300 answered a question Unable to Import Key Pair Hello, The article you mentioned is passing the x509 certificate to the instance through instance user_data, not as a keypair: nova boot --flavor 2 --image your_windows_image --key-name key1 vm1 --user_data=your_cert.pem  That being said, since then, support for x509 has been added to nova-api (but not horizon). See the help for the nova keypair-add command: usage: nova keypair-add [--pub-key ] [--key-type ] [--user ] Create a new key pair for use with servers. Positional arguments: Name of key. Optional arguments: --pub-key Path to a public ssh key. --key-type Keypair type. Can be ssh or x509. (Supported by API versions '2.2' - '2.latest') --user ID of user to whom to add key-pair (Admin only). (Supported by API versions '2.10' - '2.latest')  This has been introduced in nova-api v2.1 (microversion 2.2), so make sure you have that registered as an endpoint: openstack endpoint list # you should see something like this: # | 34291deac24a4a9195c340b70f03830f | RegionOne | nova | compute | True | admin | http://10.14.0.149:8774/v2.1 |  If not, you'll have to register a new endpoint for the /v2.1 URL, and then run a command like this: nova --service-type endpoint_name keypair-add ...  By default, the microversion 2.latest is used, but if not, you will probably want to be explicit: nova --service-type endpoint_name --os-compute-api-version 2.2 keypair-add ...

It's a very bizarre exception, IMO. It basically means that there are at least 2 switch ports with the same ElementName on the same host, which should not be possible.

As previously mentioned, Hyper-V supports only VHD / VHDX images. You can find some already prepared images here: [1] Secondly, make sure that you have the hyperv mechanism driver added in the Neutron server's ml2_conf.ini file in the mechanism_drivers list. Keep in mind that the neutron-hyperv-agent agent doesn't support VXLAN networks [2]. If you want VXLAN / GRE or other network types, you should take a look at Windows OVS + neutron-ovs-agent instead.

A VM's NIC name is the same as its neutron port name.

Also, the guide you have linked is a bit outdated. We have a much simpler and updated guide here: [1] Best regards, Claudiu Belu 2016-11-17 17:34:02 +0300 answered a question Hyper-V cluster with Newton Hello, Unfortunately, some bits regarding how the drivers are loaded changed in Newton, and now the valid drivers are: # clustered driver compute_driver=compute_hyperv.cluster.driver.HyperVClusterDriver # regular driver compute_driver=compute_hyperv.driver.HyperVDriver  Let us know if you have any further questions! Best regards, Claudiu Belu 2016-11-17 17:15:58 +0300 answered a question Cloudbase-init 0.9.9 timing and sysprep Hello, This is might not directly answer your question, but regarding the "unreachable network error", the symptoms you're describing sound like the VM's neutron ports were bound after the VM started. There is a feature in nova, which basically makes nova-compute wait for Neutron vif plug events before starting the VMs. This ensures that the VMs neutron ports and security groups are already processed and bound, ensuring that the VM will have network connectivity. The config option is called vif_plugging_timeout [1]. There is also a config option calledvif_plugging_is_fatal, which will cause the VM to fail to spawn on a host, if the Neutron vif plug events did not occur during the vif_plugging_is_fatal period. We've introduced this feature into compute-hyperv in Mitaka. What OpenStack version are you using? What hypervisor are you using?

Is there a way to force freerdp to require that the user retype the username and password? (duplicate question) I notice that when I use FreeRDP to connect to Windows Server 2012 and subsequently log off, that when I go back to the FreeRDP login screen that it retains my credentials. Is there a way to force FreeRDP to blank out the User ID and password fields so they need to be re-entered? 2016-11-11 23:41:48 +0300 answered a question error with neutron client Hello, From what I can see in the trace, it seems that there are some configurations missing from the neutron section of the Hyper-V compute node's nova.conf file, in particular, configurations regarding keytone authentication. Our Hyper-V Nova compute installer already takes care of such configurations. Also, make sure that you put traces like this into http://paste.openstack.org . This will make reading traces / logs a lot easier. [1] https://github.com/cloudbase/hyperv-n...

Hello, The driver was developed and tested under the Kilo release of OpenStack. Devstack is not mandatory. Please do keep in mind that the VirtualBoxDriver is meant for development only.

Best regards, Claudiu Belu 2016-11-11 23:17:13 +0300 answered a question hyper-v and kvm live migration Hello, No, it is not possible, for many possible reasons. In nova, you cannot simply live / cold migrate across hypervisors. Plus, there are many other things to consider, like adding / removing certain drivers (VirtIO, Linux Integration Services, etc.). The easiest approach to this would be using Coriolis [1], which will help you migrate your VMs accross hypervisors, and to / from public clouds like Azure, AWS, etc. Not to mention that it has integration with Keystone, which means that it'll magically fit in your OpenStack deployment. Best regards, Claudiu Belu 2016-11-11 23:03:07 +0300 answered a question how to increase the rdp speed Hello, FreeRDP's / FreeRDP-WebConnect's performance has increased in the meanwhile. Download the latest stable version and try it out. Best regards, Claudiu Belu 2016-11-11 22:59:56 +0300 answered a question how do i migrate my virtual machines from openstack to Azure using openstack hyper v nova compute Hello, Yes, it is possible. Please see more details about Coriolis [1] Best regards, Claudiu Belu 2016-11-11 22:57:28 +0300 answered a question nova-compute not attaching VM to a Hypver-V vSwitch Hello, The trace you've posted is not the cause of your problem (but the source of it has been fixed). It seems that there is a misconfiguration in your environment. You should take a look at the Hyper-V Neutron Agent guide [1] for debugging networking issues, but my guess is that you have not configured Neutron to use the hyperv mechanism_driver. More details in the article. Best regards, Claudiu Belu 2016-11-11 22:42:41 +0300 edited answer PortBindingFailed Hello, In order to bind Neutron ports on Hyper-V, make sure you have networking-hyperv installed on your Neutron controller node (for liberty, use 1.0.4: pip install networking-hyperv==1.0.4). Afterwards, make sure to configure your Neutron server to use the hyperv mechanism_driver, by adding it to the mechanism_drivers config option in /etc/neutron/plugins/ml2/ml2_conf.ini. You should have something like: mechanism_drivers=openvswitch,hyperv. You can have any other mechanism drivers in the list. For more details and more help in setting up and debugging any networking issues, please follow the article: Best regards, Claudiu Belu
