[Users] What are you looking for from oVirt?
Hi everyone, That is a grand subject for my first "proper" email to the Users list, and it definitely needs some context! So let me introduce myself. My name is Dave Neary, and I recently started working for a group which is being formed inside Red Hat called OSAS (open source and standards). The role of my group is to help make any open source projects that Red Hat works in successful, and I would really like to help take oVirt to the next level in terms of adoption and contribution. One of the things I'm still figuring out is what the natural audience for oVirt is, and what you all like about oVirt, and would like to see improved. Based on that, I would like to propose areas we as a community can concentrate on related to the product, the website, and our marketing and promotion, but the first step is still to get a better idea what the target audience for oVirt is, and should be. So - how are you using oVirt? Why did you choose it over alternatives? What do you like about it? and what would you like to see change, whether that is in terms of technical, process, or marketing changes? I'm here to help, but to do so I need your help first! Please feel free to reply to me on-list (if you'd like to start discussion) or off-list (if you'd like your feedback to be more discrete). Any feedback at all will be helpful. Thank you very much - I look forward to hearing from as many of you as possible. Regards, Dave. PS. I'm still figuring out proper mailing list etiquette for this project - I've added board@ and arch@ to CC since I expect our work to have project-wide consequences, but it's more to keep people informed at this point. Please let me know off-list if I'm doing something I shouldn't! -- Dave Neary Community Action and Impact Open Source and Standards Team, Red Hat Phone: +33 9 50 71 55 62

Just some context for folks - OSAS is the team that I work on with other people you've seen around oVirt: Leslie Hawthorn, Carl Trieloff, Jim Jagielski, and Jason Brooks. (You'll likely see others of us, such as Garrett LeSage, as we all work on upstream projects together.) Helping with the open sourcing and community growth of oVirt is really the first project the OSAS team worked on together.

Small private cloud deployments. We choose it because it was focused on KVM, RedHat driven, simple to manage, and libvirt based. Would love to see real glusterfs integration, quantum integration, and better API.

What does your deployment look like - it's be great to understand how you're using it - eg. Linux guests only, Windows, size of deployment - do your users use poweruser portal etc.
to see real glusterfs integration, quantum integration, and better API.
GlusterFS and Quantum are certainly in the works, but in a separate thread I'd love to hear feedback on the API what the issues/enhancements are. Would you be able to post some initial comments on that? thanks Aic

I have 2 deployments I am working on with two different companies. The first is two clusters (SJC and NYC) each with 20 boxes PXEBooted to a backend NetApp. All guests are Linux (Centos, RHEL, and Fedora). One of the unique things with the clusters is they use read only linux and NFS root. The 2nd is still in design stage, but is starting out with 3 clusters (East / West US and Europe) each with 20 boxes. Each server is based on white label Xeon E5-2687W, 128GB RAM, 10GBase-T, and 12 SATA disks on a hardware RAID 6 controller. This is also going to use shared NFS read only root with PXEBoot from NetApps. I have been running GlusterFS on and off for 5 years and are looking at running GlusterFS on all the raw 300TB RAID6 in each server. Each server will be a brick, two servers with distribute for redundancy, 10 distribute pairs then will be unified. I have been trying to use this for raw image store for years, but its just not ready, so we will use NetApp for that, however GlusterFS will be very handy for tier 2 bulk storage.

APIs are great today on the backend, we are looking at the ability to modify the front end so we can tie it into our portal allowing users to manage their VMs seamless with the other services we offer.

So - how are you using oVirt? Right now we are testing it. Running the engine in a vmware guest and have 2 servers to act as nodes. Looking at a way to replace VMware.
Why did you choose it over alternatives? Open Stack requires much larger clusters and is more cloud then data center in it design. Most of the other projects I have looked at are either designed to be AWS clones or designed for extreme flexibility making then very hard to use (Open Nebula)
What do you like about it? Web interface is simple and fairly easy to work with. Has some really nice feature built in like live migrations flexable in the hardware it works with (Compared to Xen and it CPU must be almost exactly the same). and what would you like to see change, whether that is in terms of technical, process, or marketing changes? I would like to see the project move away from its RHEV/RHEL roots some more.
Example: When started a VM you have a choice of a dozen windows / rhel versions and Other Linux NO choices for Fedora, CentOS, Ubuntu, Debian, or other Linux based systems. It makes since for RHEV since those are the only OS they official support but ovirt wants to run on other OS it should at least start with something visiable like this. The guest agent only exist for Windows, RHEL, Fedora, and CentOS (Someone outside the project created). Where is the agents for Debian based ones? Or even a list of requirement to build the agents? If it exists someone please point me to it. The really isn't a clear index on the wiki stuff is all over the place. Features pages that are added when development starts but most of the time no one updates them when the feature is implemented or changes are commited.

Hi Dave, everyone I have run a Web Hosting from 10 years ago. I integrated the Web Hosting server with KVM 2 years ago. I thought I tried to offer the VPS server which was rare in Japan, using the remaining resources. I am a server engineer, not a programmer. Regrettably, VPS market has stabilized at a low price while I spent much time in programming the "Administrator Portal" and "User Portal". However, the VPS and the cloud have restrictions even now. * Can not use your favorite OS.(That can only be used a template) * Can not strengthen by focusing on specific performance. I want to provide services which improve this issue I do not have money to buy expensive software, such as RHEV. When I started to give up the dream, I found a oVirt. Now, I am studying the feasibility of a dream by oVirt. I hope to be able to concentrate on infrastructure design without programming by oVirt However I feel that there is not enough stability yet if VPS is provided with oVirt version for now. oVirt community has companies such as RedHat. I believe that the operation of the oVirt will be stable in the version of near future. I was late in the VPS market. I have "chagrin" in the VPS market. I want to be a pioneer in Japan as that does not happen in oVirt. Therefore, I forward preparing offers of VPS using oVirt in the fall. I hope "the Japanese translation" and "stabilization" of oVirt than new features. thanks. P.S. I seek the formation of Japanese community in order to become one of the pioneers. --------------------------------------------------------------------- SeireiNetwork representative director : Takamune Konishi 19F HiltonPlazaWest 2-2-2 Umeda Kita-ku Osaka Japan Corp http://seirei.ne.jp/ Blog http://konishi.me/ <= oVirt Install Guide ISP http://vpos.seirei.ne.jp/ WebHosting http://seirei.ath.cx/ tel +81-6-7494-6690 --------------------------------------------------------------------- 2012/6/13 Dave Neary <dneary@redhat.com>:

I could have created this list myself. I have hit pretty much every one of these limits in the last few months working with the project. 3.1 adds limited support for Gluster and ovirt seems to be more stable dispute F17 instability. As for the question of stability the file storage system in 3.0 can be a bit unstable. If your NFS share disappears for a few mins the file system tends to go offline and wont reactivate. Not sure about iscsi or FC since I don't have access to those file systems.
This is all giving me great insight into who's here - please keep it coming!

3.1 adds distinction between a storage domain going down due to an error or admin maintaining it. in case of an error, there is a new recovery mechanism in 3.1 which should improve this. Itamar

Hello, I don't run currently any oVirt deployement in production but I have a lab. I used to run in production the old oVirt product (in rails). My best wishes for the future release of oVirt are : * GluserFS support as many of us * Nova (OpenStack Hypervisor) driver support ( http://docs.openstack.org/trunk/openstack-compute/admin/content/selecting-a-... ). I choose oVirt because my first goal is to manage a virtualized datacenter with OSS. But we begin to look at private cloud deployement. I think Aeolus would work with oVirt virtualization backend but AFAIK it only support redhat based linux which is not possible for us as we run almost only debian server except for virtualisation layer. So we would like to deploy OpenStack but to rely on oVirt for KVM hypervisors. * Fully supported stateless ovirt-node Regards, Romain 2012/6/28 Robert Middleswarth <robert@middleswarth.net>

I must admit the first part of managing GlusterFS with 3.3 works very well out of the box on oVirt 3.1. Turn on GlusterFS in the cluster Add your nodes Manually add the peers in Gluster Edit /etc/nfsmount.conf and set Defaultproto=tcp and Defaultvers=3 Create your gluster volume Start the volume Mount it in on one of your nodes in say /mnt chown 36.36 /mnt The only problem now is that you have to now use the volume as a NFS server.

i have these steps courtesy of haim ateya worth trying: * add new volume constructed from one brick - volume name = myVol - brick dir = /opt/myBrick * start volume - ssh to node * chown -R vdsm:kvm /opt/myBrick - using ovirt do the following): * create new DC (Posix compliant FS) * create new cluster * add new host (virt) * new domain dialog - path = node:/myVol - VFS Type = glusterfs - Mount Options = vers=3 * if start vm failedt to selinux - disable SELINUX on host you would need the newer kernel with direct_io iirc

i have these steps courtesy of haim ateya worth trying: * add new volume constructed from one brick - volume name = myVol - brick dir = /opt/myBrick * start volume - ssh to node * chown -R vdsm:kvm /opt/myBrick - using ovirt do the following): * create new DC (Posix compliant FS) * create new cluster * add new host (virt) * new domain dialog - path = node:/myVol - VFS Type = glusterfs - Mount Options = vers=3 * if start vm failedt to selinux - disable SELINUX on host
you would need the newer kernel with direct_io iirc The mount options is useful to know. I have moved over to centos 6.2 since F17 was freezing up on me every 10 to 12 hours.
I am guessing I will need to wait for CentOS 6.3 to get direct IO support and hopefully live snapshots as well. I might test glusterfs as well. PS I use localhost:/volumename for NFS. Thanks Robert

I must admit the first part of managing GlusterFS with 3.3 works very well out of the box on oVirt 3.1.
Turn on GlusterFS in the cluster Add your nodes Manually add the peers in Gluster Edit /etc/nfsmount.conf and set Defaultproto=tcp and Defaultvers=3 Create your gluster volume Start the volume Mount it in on one of your nodes in say /mnt chown 36.36 /mnt

For the record. This instructions worked also. Will make a note about this as well. Thanks Robert

Hello,
I don't run currently any oVirt deployement in production but I have a lab. I used to run in production the old oVirt product (in rails).
My best wishes for the future release of oVirt are : * GluserFS support as many of us * Nova (OpenStack Hypervisor) driver support ( http://docs.openstack.org/trunk/openstack-compute/admin/content/selecting-a-... ). I choose oVirt because my first goal is to manage a virtualized datacenter with OSS. But we begin to look at private cloud deployement. I think Aeolus would work with oVirt virtualization backend but AFAIK it only support redhat based linux which is not possible for us as we run
Aelous has a RHEVM/oVirt driver that works today. If there are problems getting Aeolus working with oVirt we should dig into it, there shouldn't be any issues.
almost only debian server except for virtualisation layer. So we would like to deploy OpenStack but to rely on oVirt for KVM hypervisors.
Out of interest what are you getting from OpenStack that you don't get from oVirt
* Fully supported stateless ovirt-node
Regards,
Romain

So - how are you using oVirt? Why did you choose it over alternatives?
What do you like about it? and what would you like to see change,
whether that is in terms of technical, process, or marketing changes?
I'm here to help, but to do so I need your help first!
Thank you to all those who have replied, on and off list, so far. For those of you who sent me private messages, I'll be (anonymously) collating your feedback and forwarding it on.
The range of users who have replied so far includes:
* Sysadmin at small web hosting business
* Cost-sensitive IT department of an unrelated industry
That would be me.
* Hosting provider specialising in HA
* Running a private cloud
* Test lab set-up considering for production deployment
Well no one should be crazy enough to go live with a product they haven't at least ran inside a testing lab.
And the top features you've cited are:
* Stateless hypervisor
* Ability to migrate VMs
Number one reason I am working with oVirt
* RHEL and KVM
We are a debian based org so changing over to the RHEL based OS's is more a pain then a benefit. KVM is still kinda young compared to both Xen / Vmware it seems to work well but there aren't as many os's covered by the vitro drivers and there seem to be more bugs / race conditions but that has been steadily changing as it has been getting more mature
* Cost
* The ability to have your preferred OS as both hypervisor and guest as a first class citizen
* Aimed for data center use-case rather than cloud
This would be number 2 in the list.
And the top gaps you've identified so far:
* Insufficient resources (docs) to help with production deployment on ovirt.org
* Difficulty of configuration and getting started
* You'd like to see a more diverse contributor community
* Stability (unfortunately, I don't have any concrete examples of this from the commenter)
* History on resource usage in hypervisors and guests
* Integration with Gluster
* Offer choices of guest agents with other distributions than RHEL
I could have created this list myself. I have hit pretty much every one of these limits in the last few months working with the project. 3.1 adds limited support for Gluster and ovirt seems to be more stable dispute F17 instability.
As for the question of stability the file storage system in 3.0 can be a bit unstable. If your NFS share disappears for a few mins the file system tends to go offline and wont reactivate. Not sure about iscsi or FC since I don't have access to those file systems.
This is all giving me great insight into who's here - please keep it coming!
Cheers,
Dave.
