[one-users] CfP VHPC20: HPC Containers-Kubernetes
CALL FOR PAPERSa 15th Workshop on Virtualization in High-Performance Cloud Computing (VHPC 20) held in conjunction with the International Supercomputing Conference - High Performance, June 21-25, 2020, Frankfurt, Germany. (Springer LNCS Proceedings) Date: June 25, 2020 Workshop URL: vhpc[dot]org Abstract registration Deadline: Jan 31st, 2020 Paper Submission Deadline: Apr 05th, 2020 Springer LNCS Call for Papers Containers and virtualization technologies constitute key enabling factors for flexible resource management in modern data centers, and particularly in cloud environments. Cloud providers need to manage complex infrastructures in a seamless fashion to support the highly dynamic and heterogeneous workloads and hosted applications customers deploy. Similarly, HPC environments have been increasingly adopting techniques that enable flexible management of vast computing and networking resources, close to marginal provisioning cost, which is unprecedented in the history of scientific and commercial computing. Most recently, Function as a Service (Faas) and Serverless computing, utilizing lightweight VMs-containers widens the spectrum of applications that can be deployed in a cloud environment, especially in an HPC context. Here, HPC-provided services can be become accessible to distributed workloads outside of large cluster environments. Various virtualization-containerization technologies contribute to the overall picture in different ways: machine virtualization, with its capability to enable consolidation of multiple underutilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; OS-level virtualization (i.e., containerization), with its capability to isolate multiple user-space environments and to allow for their coexistence within the same OS kernel, promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; lastly, unikernels provide for many virtualization benefits with a minimized OS/library surface. I/O Virtualization in turn allows physical network interfaces to take traffic from multiple VMs or containers; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology is furthermore enabling virtualization of HPC infrastructures. Publication Accepted papers will be published in a Springer LNCS proceedings volume. Topics of Interest The VHPC program committee solicits original, high-quality submissions related to virtualization across the entire software stack with a special focus on the intersection of HPC, containers-virtualization and the cloud.

Hi to all I'm planning a new opennebula infrastructure what do you suggest as shared storage? Gluster or ceph? it would be used as system image running images directly and not as simple golden image hosting Gluster is easier to setup and administer but ceph seems to be much more used in openstack ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

Re: [one-users] DISK 0: User 0 does not own an image with name
That's why if you're hard-coding your templates like that, you should be using the UID + Name if you want compatability; OR you use only Image ID directly, as it will never fail. Also remember guys, OpenNebula Mailing List is now a Forum. -- On Fri, 29 May 2015 05:52:31 -0700, Robert Foote rfo...@bpsnode.com wrote: Ok, see how the disk image is called 'imgCentOS7' in oneadmin show 1, however your template is trying to use the name ' diskCentOS7' for the image name.

Re: [one-users] I am getting following error when i tried to install CentOS VM with an ISO file and an empty Datablock. Boot failed: Could not read from CDROM (code 0004) No bootable device.
Hello Vivek, Could you tell which version of OpenNebula you're running ? Could you paste the template you're using to instantiate your VM ? If you just want to run a basic CentOS image, you can use the one available on OpenNebula's Marketplace (available from Sunstone).

[one-users] CfP Virtualization in High-Performance Cloud Computing Workshop (VHPC '15)
= CALL FOR PAPERS 10th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '15) held in conjunction with Euro-Par 2015, August 24-28, Vienna, Austria (Springer LNCS) = Date: August 25, 2015 Workshop URL: http://vhpc.org Paper Submission Deadline: May 22, 2015 CALL FOR PAPERS Virtualization technologies constitute a key enabling factor for flexible resource management in modern data centers, cloud environments, and increasingly in HPC as well. Providers need to dynamically manage complex infrastructures in a seamless fashion for varying workloads and hosted applications, independently of the customers deploying software or users submitting highly dynamic and heterogeneous workloads. Thanks to virtualization, we have the ability to manage vast computing and networking resources dynamically and close to the marginal cost of providing the services, which is unprecedented in the history of scientific and commercial computing. Docker et al. OS-level virtualization, with its capability to isolate multiple user-space environments allows for their co-existence within the same OS kernel. It promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; coupled with lightweight OSs it forms a potent architecture with promise to become a mainstream environment for HPC workloads. Machine virtualization, with its capability to enable consolidation of multiple under-utilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; I/O Virtualization allows physical network adapters to take traffic from multiple VMs; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology and IP addressing, provides the fundamental ground on top of which evolved network services can be realized with an unprecedented level of dynamicity and flexibility; These technologies have to be inter-mixed and integrated in an intelligent way, to support workloads that are increasingly demanding in terms of absolute performance, responsiveness and interactivity, and have to respect well-specified Service- Level Agreements (SLAs), as needed for industrial-grade provided services. The Workshop on Virtualization in High-Performance Cloud Computing (VHPC) aims to bring together researchers and industrial practitioners facing the challenges posed by virtualization in order to foster discussion, collaboration, mutual exchange of knowledge and experience, enabling research to ultimately provide novel solutions for virtualized computing systems of tomorrow. The workshop will be one day in length, composed of 20 min paper presentations, each followed by 10 min discussion sections, and lightning talks, limited to 5 minutes. Presentations may be accompanied by interactive demonstrations. TOPICS Topics of interest include, but are not limited to: - Virtualization in supercomputing environments, HPC clusters, cloud HPC and grids - OS-level virtualization including container runtimes (Docker, rkt et al.) - Lightweight compute node operating systems/VMMs - Optimizations of virtual machine monitor platforms, hypervisors and - Hypervisor and network virtualization QoS and SLAs - Cloud based network and system management for SDN and NFV - Management, deployment and monitoring of virtualized environments - Performance measurement, modelling and monitoring of virtualized/cloud workloads - Programming models for virtualized environments - Cloud reliability, fault-tolerance, high-availability and security - Heterogeneous virtualized environments, virtualized accelerators, GPUs and co-processors - Optimized communication libraries/protocols in the cloud and for HPC in the cloud - Topology management and optimization for distributed virtualized applications - Cluster provisioning in the cloud and cloud bursting - Adaptation of emerging HPC technologies (high performance networks, RDMA, etc..) - I/O and storage virtualization, virtualization aware file systems - Job scheduling/control/policy in virtualized environments - Checkpointing and migration of VM-based large compute jobs - Cloud frameworks and APIs - Energy-efficient / power-aware virtualization Important Dates April 29, 2015 - Abstract registration May 22, 2015 - Full paper submission June 19, 2015 - Acceptance notification October 2, 2015 - Camera-ready version due August 25, 2015 - Workshop Date TPC CHAIR Michael Alexander (chair), TU Wien, Austria Anastassios Nanos (co-chair), NTUA, Greece Balazs Gerofi (co-chair), RIKEN Advanced Institute for Computational Science, Japan PROGRAM
[one-users] vOneCloud - Folder Deployment Selection
Hello OpenNebula Users, I received the announcement that vOneCloud has been released today so I thought I'd spin it up since we're currently in the market for a self service cloud portal to enable customers to deploy VMs to our vSphere infrastructure. This was really easy to setup (compared to VIO for instance), I'm really impressed. However, I can't seem to figure out how to select which folder to deploy VMs to. Currently when I instantiate a template it's created in the TEMPLATES folder where all of the discovered templates are. I'm currently using the CloudAdmin user / I'm the vSphere admin so it's not a big deal to just drag it to the appropriate folder, but as we start opening this up to other users we'll want to restrict them to their assigned resources and it's not really feasible to have someone continue to do that. Our current permissions model calls for each customer to have their own: Resource pool, vSphere folder, port group, and datastore. Is there a way to select app pool? Can vOC import existing app pools? The way we've implemented permissions seems to be a similar concept to the VDC. My ultimate goal is to be able to have OpenNebula available but still allow users access to vCenter for the time being (basically a transitional period for lack of a better word). Is that something that is possible in the current version of vOneCloud? I'm glad I've stayed subscribed to the mailing list, you guys do awesome work. Thanks, Jon A ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] Fwd: Support for ESX 4.1?
Hi, According to 4.12 document, vmware support is ESX 5.5 and vCenter 5.5. Currently, we are still running ESX vsphere 4.1 environment. Will the latest opennebula support ESX 4.1? Or do I have to downgrade in order to support ESX-4.1? We are trying to slowly phase out ESX and use open source hypervisor, so opennebula may be a good candidate for us to manage our old esx and well as new kvm, while we slowly phase out esx. However I am not sure if vsphere-4.1 is supported. Can anyone enlighten me before I start testing it? Thanks.

Hi All, i installed opennebula 4.12 on ubuntu 14.04 using (apt-get) Log shows the error as command execution fail, if [ -x var/tmp/one/im/run_probes] .. , hostkey verification failed I tried (i) onehost sync, and onehost delete and add also… (ii) added ~ssh/config also (iii) Permission to /var/tmp/one/im/run_probes also . However I can run the script “ /var/tmp/one/im/run_probes….”, ( shows all information ) kindly help for a solution. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] Error to restore a virtual machine
Hello, I have an OpenNebula 4.6.2 with vmware. When I suspend a virtual machine and I try to boot after that state (SUSPENDED), always fails and VM doesn't change of state. In vmware the VM appears power off and when I try boot it from there, it boots fine but it isn't synchronized with Sunstone. In Sunstone it appears suspended.

[one-users] Sunstone - Time out errors
Hi Everyone, We're currently experiencing a weird issue on our OpenNebula management node. The node is setup with the following configuration: - CentOS 6.6 - Two interfaces in an balance-alb bond. - MySQL backend - /var/lib/one mounted on glusterfs and shared with all nodes. - OpenNebula 4.12 - We're behind a proxy, so all proxy variables are set in the environment for all users. When working on the commandline everything works as a charm, you can list all nodes/datastores, view the details, etc. All working smooth and fast! The problem we face however is working inside the sunstone interface. It seems that listing resources (nodes and datastores) works normally but when we click a datastore/node/whatever it takes ages (minutes) before it shows the contents. The sunstone.error logs only give the following info (in debug mode): Errno::ETIMEDOUT - Connection timed out - connect(2): /usr/lib/ruby/1.8/net/http.rb:560:in `initialize' /usr/lib/ruby/1.8/net/http.rb:560:in `open' /usr/lib/ruby/1.8/net/http.rb:560:in `connect' /usr/lib/ruby/1.8/timeout.rb:53:in `timeout' /usr/lib/ruby/1.8/timeout.rb:101:in `timeout' /usr/lib/ruby/1.8/net/http.rb:560:in `connect' /usr/lib/ruby/1.8/net/http.rb:553:in `do_start' /usr/lib/ruby/1.8/net/http.rb:542:in `start' /usr/lib/ruby/1.8/net/http.rb:1035:in `request' /usr/lib/ruby/1.8/net/http.rb:772:in `get' /usr/lib/ruby/gems/1.8/gems/faraday-0.9.1/lib/faraday/adapter/net_http.rb:80:in `perform_request' /usr/lib/ruby/gems/1.8/gems/faraday-0.9.1/lib/faraday/adapter/net_http.rb:40:in `call' /usr/lib/ruby/gems/1.8/gems/faraday-0.9.1/lib/faraday/adapter/net_http.rb:87:in `with_net_http_connection' /usr/lib/ruby/gems/1.8/gems/faraday-0.9.1/lib/faraday/adapter/net_http.rb:32:in `call' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/middleware/request/retry.rb:20:in `call' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/middleware/request/encode_json.rb:21:in `call' /usr/lib/ruby/gems/1.8/gems/faraday-0.9.1/lib/faraday/request/multipart.rb:14:in `call' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/middleware/request/upload.rb:16:in `call' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/middleware/request/etag_cache.rb:31:in `call' /usr/lib/ruby/gems/1.8/gems/faraday-0.9.1/lib/faraday/request/authorization.rb:38:in `call' /usr/lib/ruby/gems/1.8/gems/faraday-0.9.1/lib/faraday/response.rb:8:in `call' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/middleware/response/parse_iso_dates.rb:11:in `call' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/middleware/response/logger.rb:20:in `call' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/middleware/response/callback.rb:14:in `call' /usr/lib/ruby/gems/1.8/gems/faraday-0.9.1/lib/faraday/response.rb:8:in `call' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/middleware/response/raise_error.rb:9:in `call' /usr/lib/ruby/gems/1.8/gems/faraday-0.9.1/lib/faraday/rack_builder.rb:139:in `build_response' /usr/lib/ruby/gems/1.8/gems/faraday-0.9.1/lib/faraday/connection.rb:377:in `run_request' /usr/lib/ruby/gems/1.8/gems/faraday-0.9.1/lib/faraday/connection.rb:140:in `get' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/actions.rb:104:in `find!' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/actions.rb:119:in `find' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/collection.rb:62:in `send' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/collection.rb:62:in `find' /usr/lib/ruby/gems/1.8/gems/zendesk_api-1.4.6/lib/zendesk_api/client.rb:56:in `current_user' /usr/lib/one/sunstone/routes/support.rb:66:in `zendesk_client' /usr/lib/one/sunstone/routes/support.rb:121:in `GET /support/request' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:863:in `call' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:863:in `route' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:521:in `instance_eval' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:521:in `route_eval' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:500:in `route!' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:497:in `catch' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:497:in `route!' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:476:in `each' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:476:in `route!' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:601:in `dispatch!' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:411:in `call!' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:566:in `instance_eval' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:566:in `invoke' /usr/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:566:in `catch'

[one-users] CfP 10th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '15)
= CALL FOR PAPERS 10th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '15) held in conjunction with Euro-Par 2015, August 24-28, Vienna, Austria (Springer LNCS) = Date: August 25, 2015 Workshop URL: http://vhpc.org Paper Submission Deadline: May 22, 2015 CALL FOR PAPERS Virtualization technologies constitute a key enabling factor for flexible resource management in modern data centers, cloud environments, and increasingly in HPC as well. Providers need to dynamically manage complex infrastructures in a seamless fashion for varying workloads and hosted applications, independently of the customers deploying software or users submitting highly dynamic and heterogeneous workloads. Thanks to virtualization, we have the ability to manage vast computing and networking resources dynamically and close to the marginal cost of providing the services, which is unprecedented in the history of scientific and commercial computing. Various virtualization technologies contribute to the overall picture in different ways: machine virtualization, with its capability to enable consolidation of multiple under-utilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; OS-level virtualization, with its capability to isolate multiple user-space environments and to allow for their co-existence within the same OS kernel, promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; I/O Virtualization allows physical network adapters to take traffic from multiple VMs; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology and IP addressing, provides the fundamental ground on top of which evolved network services can be realized with an unprecedented level of dynamicity and flexibility; These technologies have to be inter-mixed and integrated in an intelligent way, to support workloads that are increasingly demanding in terms of absolute performance, responsiveness and interactivity, and have to respect well-specified Service- Level Agreements (SLAs), as needed for industrial-grade provided services. Indeed, among emerging and increasingly interesting application domains for virtualization, we can find big-data application workloads in cloud infrastructures, interactive and real-time multimedia services in the cloud, including real-time big-data streaming platforms such as used in real-time analytics supporting nowadays a plethora of application domains. Distributed cloud infrastructures promise to offer unprecedented responsiveness levels for hosted applications, but that is only possible if the underlying virtualization technologies can overcome most of the latency impairments typical of current virtualized infrastructures (e.g., far worse tail-latency). The Workshop on Virtualization in High-Performance Cloud Computing (VHPC) aims to bring together researchers and industrial practitioners facing the challenges posed by virtualization in order to foster discussion, collaboration, mutual exchange of knowledge and experience, enabling research to ultimately provide novel solutions for virtualized computing systems of tomorrow. The workshop will be one day in length, composed of 20 min paper presentations, each followed by 10 min discussion sections, and lightning talks, limited to 5 minutes. Presentations may be accompanied by interactive demonstrations. TOPICS Topics of interest include, but are not limited to: - Virtualization in supercomputing environments, HPC clusters, cloud HPC and grids - Optimizations of virtual machine monitor platforms, hypervisors and OS-level virtualization - Hypervisor and network virtualization QoS and SLAs - Cloud based network and system management for SDN and NFV - Management, deployment and monitoring of virtualized environments - Performance measurement, modelling and monitoring of virtualized/cloud workloads - Programming models for virtualized environments - Cloud reliability, fault-tolerance, high-availability and security - Heterogeneous virtualized environments, virtualized accelerators, GPUs and co-processors - Optimized communication libraries/protocols in the cloud and for HPC in the cloud - Topology management and optimization for distributed virtualized applications - Cluster provisioning in the cloud and cloud bursting - Adaptation of emerging HPC technologies (high performance networks, RDMA, etc..) - I/O and storage virtualization, virtualization aware file systems - Job scheduling/control/policy in virtualized environments - Checkpointing and migration of

[one-users] Ruby problem Centos 7 pcsd and Opennebula
Good morning, I am building a block LVM KVM cluster with 4 machines, but i am having a strange problem which keeps me busy for days now, i am using a standard Centos 7 server as frontend and Centos 7 nodes with opennebula and opennebula-server installed. software installed opennebula-ruby-4.8.0-1.x86_64 opennebula-common-4.8.0-1.x86_64 opennebula-sunstone-4.8.0-1.x86_64 opennebula-4.8.0-1.x86_64 opennebula-server-4.8.0-1.x86_64 I also installed pcs-0.9.115-32.el7_0.1.x86_64 to use clvmd en dlm locks on the opennebula nodes and frontend. Now the problem i am facing i have installed pcsd (ruby) and opennebula (ruby) on the same machine, when i install rack and sinatra via gems as ordered by the install in the documentation the psc daemon binds only to the localhost interface. If i uninstall sinatra and rack then the psc daemon listens as ordered via the config file on all interfaces but opennebula won't start! After installing sinatra via gems their are 2 versions of sinatra on the system /usr/lib/pcsd/vendor/bundle/ruby/gems/sinatra-1.4.4/lib/sinatra /usr/local/share/gems/gems/sinatra-1.4.5/lib/sinatra So i assume something is overruling BindAddress directive in the config of pscd on centos 7 when i install the software needed to run opennebula. I have tried setting the BindAddress directive in ssl.rb to *, nil and :: but nothing fixes the problem also my knowledge of ruby is to low to investigate further. see below howto reproduce this problem [root@cloudmanager rack-1.6.0]# !lsof lsof -i | grep ruby ruby 1368 root9u IPv6 1474379 0t0 TCP localhost:efi-mg (LISTEN) ruby 1368 root 10u IPv4 1474380 0t0 TCP localhost:efi-mg (LISTEN) ruby 13803 oneadmin 10u IPv4 913310 0t0 TCP *:9869 (LISTEN) [root@cloudmanager rack-1.6.0]# gem uninstall sinatra rack Successfully uninstalled sinatra-1.4.5 Successfully uninstalled rack-1.6.0 [root@cloudmanager rack-1.6.0]# systemctl restart pcsd.service [root@cloudmanager rack-1.6.0]# !lsof lsof -i | grep ruby ruby 4377 root9u IPv4 1739444 0t0 TCP *:efi-mg (LISTEN) ruby 13803 oneadmin 10u IPv4 913310 0t0 TCP *:9869 (LISTEN) [root@cloudmanager tmp]# gem install sinatra Successfully installed rack-1.6.0 Successfully installed sinatra-1.4.5 [root@cloudmanager tmp]# systemctl restart pcsd.service [root@cloudmanager tmp]# !lsof lsof -i | grep ruby ruby 4551 root9u IPv6 1740682 0t0 TCP localhost:efi-mg (LISTEN) ruby 4551 root 10u IPv4 1740683 0t0 TCP localhost:efi-mg (LISTEN) ruby 13803 oneadmin 10u IPv4 913310 0t0 TCP *:9869 (LISTEN) Any tips how i can solve this problem?

[one-users] Problems after update from 4.8 to 4.10 and one question.
After updating from 4.8 to 4.10 my sunstone and oned became very very slow. Listing logs for a VM can take a minute or two, when before update it took about second or two. Also migrating live, creating VM or any other operation are now 10 times slower. Anyone had similiar problems? Also i want to now how can i limit a group to get access only to certain networks. I created group called test, gave them permission to use template and images, also i gave them to use only one network permission, but on the network list while adding interface i can see all of my networks available. Is there any way to get rid of seeing all the networks ? ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
Re: [one-users] VMM 'unknown' state not being set?
We set the VMM to report :deleted and it went into 'unknown' state, which is perfect for us as we can then issue a VM cancel and it will clean up the VM on the hypervisor as well.

Re: [one-users] Clone images in datastore /w TM_MAD=qcow2
Hi Dimitri, We are moving the community to the new forum by the end of the week [1]. This last week things are getting even worse with the hosting company... seems a good time to move on ;) Anyway there are two drivers DS and TM. QoW is used for TM when a persistent image (or master/golden) is cloned to fire a new VM. The original image is moved to used state and so it won't be deleted. On the other hand, a DS clone operation creates a completely (read independent from) the original image. Using QoW for this would be faster, but we will need more logic to flatten the snapshots when the original is deleted, and potentially we will end up with multiple snapshot layers that will degrade performance.

Re: [one-users] Setting filesystem type for new disk crashes GlusterFS
I've missed this one, sorry.
Searching for your problem I've found people with the same problems using
glusterfs and XFS. Also XFS is usually the backing storage for gluster, at
least that's what most of the howtos say.
That's good to know that a new version solved the problem.

Hi,
There seems to be a problem with sparse files and glusterfs and/or the
underlying FS (XFS?).
No, it's only in combination with mkfs. Creating sparse files without a
preset filesystem (i.e. raw images) works perfectly.
By the way: How did you figure out that XFS is used? Is it known to
produce problems?
In addition to your suggestions, I experimented with overriding the
filesystem type setting by setting FSTYPE = raw in
/var/lib/one/remotes/tm/shared/mkimage. As far as I tested, that worked as
well. However, we recently upgraded to Ubuntu 14.04 and GlusterFS 3.4.2.
Now the bug seems to be gone.
Thanks anyway!

You can disable that functionality adding an exit 1 command at the
top of these scripts:
* /var/lib/one/remotes/datastore/mkfs
* /var/lib/one/remotes/tm/mkimage
Another way of solving this is changing the what the image is created
(so it is not sparse). The problem is that it will take a lot more
time to create the image. The commad to change is 'dd' from those
scripts. For example, for 'mkfs':
exec_and_log $DD if=/dev/zero of=$DST bs=1 count=1 seek=${SIZE}M \
Could not create image $DST
to
exec_and_log $DD if=/dev/zero of=$DST bs=1M count=${SIZE} \
Could not create image $DST

Hi,
Our OpenNebula setup uses GlusterFS to share /var/lib/one among all
machines. Yesterday a customer created a new volatile disk for a VM. But
this image creation crashed the gluster client on the host the VM was
running on. I assume it has something to do with the fact that the
customer
entered 'ext3' as filesystem type.
This isn't the first time this bug occured, we also had it almost one
year
ago and there it was also related to the filesystem type of an image. I
believe that this feature is rarely used by our customers and simply
wasn't
used in the meantime. Now we are using OpenNebula 4.8.0 on Ubuntu
12.04.5

We tried 'p' but it means we can't cancel the VM. We have to resume the VM just to stop it, and then cancel it.

Hi:

bug... bug the patch seems to be into some branch

I don't pretend to confuse you with how we discover this bug, but in
short it appears when executing some accounting software by Boris Parak for
the Federate cloud of the EGI project
I hope the patch i link help to clarify the situation.

Hi to all.
As Esteban say, we have a planned updated to last stable opennebula
release the Wednesday 18th, but i think we can wait if the libxmlrpc-c
is updated in the next days or maybe weeks.
I think we can wait because the new ON not have critical changes (we
have pached one-flow yet) and make 2 updates in the same month can be a
problem for our costumers... (we use oneflow in a lot of critical
services and is a problem make 2 scheduled stops)
But if the change is programated to 4.12 we going to update and patch it
(I think Ruben have a special love story paching software hehe)
Again, a lot of thanks.

Hi Carlos,
Thank you very much for checking it :)
About if it should be fixed in 1.33.14, I hope Rubén answer to this
tomorrow since it is the one looking at this issue.
When do you think we could test this? Sorry for the question/hurry but
we are failing accounting due to this issue in FedCloud (EGI). In
principle, we are going to update to last ON version next Wednesday
18th.
Thanks in advance,

Hi,
That IP looks good (202.45.142.114). It might be a bug that can be affected by
the ruby version.
Since this is a 4.2 version and the leases were completely redone for new
versions, maybe the best thing to do is comment out the whole vnet section in
fsck.rb, lines 920-1066.

Yes... that's the way we usually do it: by cherry picking the commits. Ok, I'll broke everything to rebase on master then. Unfortunately we don't think there's an easier way. Personally, I prefer to use DaggyFix[1][2] over cherry-picking. This requires to base the commits on the oldest supported release and then merge them everywhere needed, which can be seen as a lot of work, but not that much different from doing cherry-picking ;-) I think DaggyFix is more GIT friendly and respect the context as explain in an article I just found[3]. For example, here is the GIT graph to apply a foo-bar patch (issue #42): o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-M₃ - master \ \ \ \ / \ \ \ o-o-o-o-M₂ /- prod/4/master (integration branch for version 4) \ \ \ / / \ \ \ o-o---+ - prod/3/42-foo-bar (short living branch) \ \ \ / \ \ \ o-o-o-o-M₁ - prod/3/master (integration branch for version 3) \ \ \ o-o-o-o-o-o-o-M₀ - prod/2/master (integration branch for version 2) \ \ / \ o-o-o-o - prod/2/41-fix-something \ o-o-o-o-o-o - prod/1/master (integration branch for version 1) in this example: - version 1 is not supported anymore - version 2 is supported but not concerned by #42: foo-bar A temporary branch is created based on version 3 named prod/3/42-foo-bar and the commits are done here. I use do to prefix my branch names by the name of the release branch it first apply to, it help to sort them when doing “git branch” ;-) Then, this 42/foo-bar branch is merge back into version 3 integration branch (commit M₁), to prepare a new release 3.X. This 42/foo-bar branch is merge into version 4 integration branch (commit M₂) if it apply to it like in my example. Finally, this 42/foo-bar branch is merge into the main development branch (commit M₃) if it apply to it like in my example. This is based on the “successful Git branching model[4]” I extended with the packaging branches. I hope it will help you, it took me time to find some kind of best practice I agree with, like “Is it better to rebase or merge?[5]”. Regards.

Compile our own OpenNebula will break the package system maintenance. You can forget use yum or any other package management system.

In the easy way, OpenNebula staff should use a fixed version of libxmlrpc-c and so distribute a fixed package of OpenNebula.

Re: [one-users] datastore layout question
Hi Steve, Normally If I have to use NFS based shared hosting then I mounted /var/lib/one directly on all nodes instead of mounting datastores seperately. Else recently I configured multiple OpenNebula Nodes with local /var/lib/one directory added one Node just for backup and sync only datastores of all nodes on that backup node. So that I can easily live migrate VMs to that backup Node from any node. It worked well for me. Pros: 1. Speedy managing instances as it uses local storage. 2. Live Migration works 3. Very Low cost compare to Fiber infrastructure 4. No need for separate Network storage as backup node can work as OpenNebula Host. Cons: 1. It cannot be realtime sync but you set cron for every minute 2. Need to monitor syncing.

That IP looks good (202.45.142.114). It might be a bug that can be affected
by the ruby version.
Since this is a 4.2 version and the leases were completely redone for new
versions, maybe the best thing to do is comment out the whole vnet section
in fsck.rb, lines 920-1066.

Hi,
I don't know what can be causing the error. Can you to add the following
lines right before line 929 in /usr/lib/one/ruby/onedb/fsck.rb?
warn
warn row[:ip]: #{row[:ip]}
warn doc: #{doc.to_s}
https://github.com/OpenNebula/one/blob/release-4.2/src/onedb/fsck.rb#L929
Maybe that will show if there is something wrong with that IP that is
throwing the error.

Appreciate the expert help on this.

Re: [one-users] about firewall
Hi, you are right, we don't have this. I just created this in order to document http://dev.opennebula.org/issues/3602 Answering your specific question: What is not clear is about the tm driver. An ssh connection is open from oned admin server to the hypervisors, to run the clone/cp/etc actions. I need to know if the hypervisor will in those actions initiate some SSH connection back to the oned admin server? (we are using ssh, shared, and lvm drivers). We want to block this king of traffic (ssh to oned admin server from the nodes). The ssh connection to the frontend from the nodes **is** required. It's used in actions like undeploy or stop. In any case as you say, creating a reference guide for the connections in OpenNebula would come in very handy. cheers, Jaime On Fri, Feb 6, 2015 at 11:07 AM, Madko madk...@gmail.com wrote: Hi, Is there any documentation about the ports and network traffic in use with OpenNebula?

Thanks, I have one issue with OpenNebula branches. I based my work on the 4.10 package[1] to compare the original package content with mine. Now, I would like to follow master and derive the packaging based on OpenNebula version, but I have a lot of conflicts when I merge master into my packaging branch. The base idea is to have one packaging branch following OpenNebula master branch. On a new release, a “release dedicated” packaging branch is derived from the master packaging branch to follow the OpenNebula release. Should I rebase[2] all my branches on master directly and then follow the OpenNebula releases or is there a path to merge master and one-4.10? Hmm, writing the question seems to gives my answer, it looks like the cherry-picking of master commits on the one-version branches are the reasons of the merge conflicts. Any hints?

I also don't generally like forums but we think we've found one that can be used mostly like a mailing list. You can subscribe to a category and you'll get all the new posts opened there. It is supported also to reply using email so you don't need to open the web interface for that. Creating new threads by email is still not enabled as we want to figure out the best way to do it. We decided to make the change as the current mailing list service does not work from time to time and the archives (when working) is almost unusable to search for old answers. The good thing about the forum interface is that the answers can be easily searched and even moved to a FAQ or Howto section.

[one-users] datastore layout question
My one4.8 installation is set up with NFS-based shared image store #102 and local-based system datastore #100 instantiated in local disk on each VM host. Thus far it seems that I am forced to set up the datastore path as /var/lib/one/datastores/dsno So that means I have to NFS export datastore #102 to all VM nodes with exactly that path (/var/lib/one/datastores/102) and then as long as the /var/lib/one/datastores path is there on the VM host the directory /var/lib/one/datastores/100 will be made when the first VM is launched. All of this works just fine but it does mean that I have to be careful every time I reset the cloud to make sure that the image datastore is created as datastore #102. If I ever end up changing the number for whatever reason I will have to change all the mount points all across the cluster. Has anyone ever figured out a better way to deal with mounting a shared NFS data store? Steve Timm -- Steven C.

Re: [one-users] clusters in 4.8
Hi My Fault, you are right the cluster requirements are also used for system datastores. Note that the default cluster behaves as described for VNETs. This behavior is not coherent with the documentation as you mentioned in a previous mail, so it seems a bug. I filled an issue [1] to look at this before 4.12.

Seems like if I require any resource from the cluster, in this case a vnet, then all resources have to be in the cluster. Am I missing something?

[one-users] Migrate OpenNebula to another host
Hi everyone, So Ive set up OpenNebula with the SQLite DB and everything is fine. Now I am tasked with changing the server which hosts OpenNebula and Sunstone, since the other server is better secured and all in all in a more reliable environment. Is there a guide for migrating ONE and Sunstone to another server or would I basically just have to install it on the other server and copy the database + configs ? What about the other opennebula-node nodes? Some hints or help would be greatly appreciated ;-) Cheers, Christian --- Christian Hüning, BSc.

Re: [one-users] How to secure VNC access?
The novnc-server will translate WebSockets traffic to normal socket traffic, therefore you don't have to expose the host IP to the final user, she will interact with the proxy. Cheers On 10 February 2015 at 11:33, Nico Schottelius nico-opennebula@schottelius.org wrote: Hey, I think I haven't (at least I didn't enable it explicitly). If the novnc-server is enabled, how do I configure the templates? Because at the moment, vnc listens to 0.0.0.0 and is accessible if someone knows the IP and port. Cheers, Nico Daniel Molina [Tue, Feb 10, 2015 at 10:54:36AM +0100]: Hi, Are you using the novnc-server included in OpenNebula? This component uses a websocket proxy, so that you don't have to expose the VNC socket to your users, and it will take care of the different tcp sockets. Cheers On 6 February 2015 at 12:50, Nico Schottelius nico-opennebula@schottelius.org wrote: Good day, we are about to setup our fourth hosting plattform in the next weeks, based on opennebula 4.10.2, ubuntu 14.0 and gluster 3.x (x ~= 4..6). In our tests the VNC socket of the VMs has been exposed on the hosts directly accessible on 0.0.0.0 - for everyone. Given that sunstone will be usable by our customers and VMs will be running on hosts other than the one running sunstone, what is the default secure alternative in opennebula? Do you support vnc / ssh tunneling like described on [0]? This process is pretty neat, because you don't need to expose VNC at all and not care about numbering of tcp sockets. I guess a combination of ssh unix socket tunneling plus spice on the frontend is probably the safest solution - what are your opinions? How do you configure VNC access at the moment?
