Oracle VM Room for Improvement

Rasika Sudasinghe - PeerSpot reviewer
Senior Director - Systems Architecture at MIT ESP

Oracle VM is an obsolete product in that no new features are coming for it. The new version is called Oracle KVM. The only improvement needed for Oracle VM is the look and feel of the interface. When comparing the user console with vCenter, the interface used to control VMware environments, Oracle VM's user interface is not that rich in terms of user experience. If Oracle could improve that, it would be good.

Besides that, we don't know if the solution comes with a roadmap because it comes free of charge with Oracle x86. We can't expect something similar to vCenter in KVM, but at least if you can improve what users can experience, then it would be good.

The solution is an outdated Xen-based application. They only perform maintenance support for it. The new version is Oracle Linux Virtualization, which is a re-skinned version of the over stack, basically the same as the one that Red Hat sells. They could harmonize management between their products better.

Initially, you did not have an option in Oracle VM to build an image and just restore into a different physical or virtual environment, but now the option is included. That's one thing I thought wasn't there and wanted to have, because we are planning to move our Essbase database server from physical to virtual, and I thought it's not going to be easier because you can't just export the physical server and just import everything into the virtual machine. Now the integration is there. You can export the physical server's configuration, their registries and everything, the databases and then just import them to virtual machines. That's the only lacking feature I thought was with VM, but they have included it. 

It still takes some time and the valuations have to be done by the admin, so it still is taking more time. That's, I think, one of the challenges that we recently had when we were talking to our administration team. The Windows and Linux admins took some time, like a couple of days, to build servers for us, which as far as I think being an IT person, it's a virtual machine. Once you have the image it should be easy enough to import it into the new virtual machine, built up like a snapshot. 

I think they could make the implementation faster. It's still taking some time, which should be eliminated in the future, I think, and it will be because I've seen a lot of improvement already.

If there are issues with the storage, then all the machines go down, even if I have a backup solution in place. So I have to restart the server, and then it starts working again. It has happened a few times, and it wasn't very comfortable. 

Apart from that, it's an okay solution for deploying VMs or switching them to another server if you have availability installed, and so on.

I'm not familiar with the latest version. There might be some new functionalities that we would like to have in our current solution. For example, having better backup options for virtual machines, such as online backup, would be cool to have.

This is something that I would like to see in our virtualization solution.

Oracle VM should have centralized storage, without which you can't clone or move one VM to another. If you have two Oracle KVM hypervisors without central storage and want to replicate a clone from one hypervisor to another, there is no technology to do that.

Oracle VM needs to change or refine its partition system. Oracle OVM takes five minutes to one hour to clone a system.

The solution lacks a lot of extra key features.

If you do a gap analysis between VMware and Oracle VM, you can't do VM Snapshot. That's one thing you can't do. It's a sort of a snapshot, but it's not really Snapshot technology. It requires that you're running on CFS-2.

There's an overall lack of integration with other software and there is also a lack of integration with backup solutions.

Oracle has stated that they intend to improve the solution. I'm not sure when this will happen, however. It may have been declared end of life, therefore, I can't imagine that they'll actually add to it at this point.

Something that could be improved are the snapshots that go in the ZFS Storage. If you want to enjoy Oracle VM, you will definitely want it to go together with ZFS Storage to maximize on the snapshot facility.

In other virtualization like VMware, you can do the snapshot right at the level of VMware itself. You'll get customers complaining that, "We can't take a snapshot just like we do on our normal VMware solution."

I always advise my customers to go with ZFS Storage. If you maybe had a snapshot on the Oracle VM itself, it would make sense.

JK
President with 201-500 employees

I've found that using Oracle VM is like stepping back in time. It's not kept up with technology. The only reason anyone uses it is that they're afraid of Oracle's licensing. Oracle has a tremendously bad licensing approach.

VMware, in comparison, has got so many different features that you can use in ESXi for example. Oracle is a lot simpler with fewer features.

I find their VM backup features to be somewhat difficult. I wish it was a little easier to back up and clone.

It would be ideal if Oracle could grow to take on VMware directly, in order to foster more competition.

Development of the product seems slow, but then again, I do not want a rushed product. Oracle states that this is their solution for their products, but Windows is fully supported. It may not have all the features of VMware, but those features come at a cost (monetarily and performance-wise). I want a rock solid foundation, and I don't want a bunch of hooks into the foundation of my Windows infrastructure.

I’d like to see an improvement in read latency and write bandwidth to meet or exceed VMware's performance, and also smooth out the variance in both. People are choosing VMware over OVM left and right despite the licensing issues. OVM needs to be faster than anyone else, especially with Oracle’s own products.

The user interface of the version that we have requires improvement. They have already improved the user interface by moving away from OVMM to OVM or KVM which uses the oVirt engine and has a completely new feel for the user interface, but we are yet to migrate to that. The new UI is much better and more intuitive.

I would like it to be simple. It is serving all of our needs, and I don't think it is necessary to keep adding. We are able to provision a VM in ten minutes, and provisioning it in five minutes will not have any added benefit.

Just keep it simple.

Better disaster recovery, though they just introduced a new technology called Oracle VM Site Guard that's helped a lot in disaster recovery.

Sr. Unix System Administrator at a media company with 1,001-5,000 employees

I would like them to include greater flexibility. I would like them to include multitudinous users and permissions capabilities. I would like them to design the system so that it is optimized for 10GB Ethernet at a minimum as opposed to 1GB Ethernet.

Oracle VM does not have what is commonly called role-based user permissions.
Everyone logs into the management console as an ‘admin’ and has full control over everything, as opposed to VMware, where you can (for example) give a particular user control over a certain virtual machine but no others. You can even give different grades of control, so a user would be able to reboot ‘his’ virtual machine but could not add disk space to it; or a storage administrator might have the right to add and delete storage but not affect any virtual machines at all.

I had a problem with Ethernet timeouts on my 10gb Ethernet connections and when I contacted them, they informed me that they had optimized their settings and values in the operating system kernel for 1gb Ethernet as was standard at the time. They gave me a listing of changes to the operating system that might optimize it for 10gb, but that might cause problems if and when I were to upgrade the system. The Oracle VM Server is not meant to be modified by the user; it is the hypervisor, and I didn’t wish to engage in the danger of modifying my base system.

I also am skilled in VMware. VMware costs about 10 times as much but also is about 10 times more usable. If they could learn that usability that VMware has, that would be wonderful.

I'm still evaluating the product and getting to know it.

The only thing I'm finding is that the backup software, which is supporting Oracle's virtualization platform, needs improvement. We're struggling to get a solution that will support my Oracle virtualization environment for backup purposes. I just found one on the internet. I was trying to reach out to that team now, to see how best we can use it. However, if Oracle had a solution to this, that would be ideal.

You need to have a model for documentation available for the users. Right now, if you have to search for some troubleshooting, you need to have Oracle login. Many personnel might not have that login. The reach, the availability of information to the end-user, is not there.

There are some articles that are publicly available, but there are some important documents that are not available to the public. You need to subscribe, or you need to have a licensed copy, some subscription with the product.

Any product, at the end of the day, needs support. When the support or the knowledge base or the information is not available or the documentation is not available for any of this, for the person who is implementing this, it's very difficult for them to get used to this product. They will simply move to another product.

  • The SR-IOV technology should be improved more as it only supports basic functions.
  • It does not have a graphical maintenance screen. The OVM manager interface has so little functionality for managing control domains only. It is not a big problem if you have experienced administrators, but it would be nice to have a beautiful screen to use for everything which guides you into not making mistakes.
  • Error handling takes the safest way, but safest way may cause business discontinuity. A few bad experiences occurred in this manner and should be fixed. For example, if you restart the server and resources assigned to virtual systems are more than available, it removes all virtual system definitions and resource assignments like WWNs. You have to redefine everything from backups. This takes time and the system is out of service in the meanwhile.
  • Virtual WWNs were lost in one of the PDOMs while it was in maintenance mode. The system continued with other servers, but all disk access paths had to be re-defined from scratch for some LDOMs. It was so annoying because this was not accepted as a bug by Oracle.

At the moment the discovery of hosts and configuration can be performed only via the GUI and not by a command line on the hosts. To resolve some other issues, we decided to install Oracle Enterprise Manager Cloud 13c to add monitoring capabilities, which OVM Manager lacks completely.

Backup: It's possible to clone a VM (Virtual Machine) or make a template from it, but the option to create a snapshot backup from OVM Manager is missing. This option is available in VMware vSphere If you want to make snapshots using Oracle VM then it must be done by the storage product.

Jobs, the OVM manager handles only one job at the time. For a lot of actions, for example, starting or stopping a Virtual Machine, a job is created. If I start a couple of VM's at the same time I only see one job for starting the first VM. The other five jobs are in an invisible queue, after finishing the first job the second job starts and becomes visible at that moment. What to improve: make at least visible which jobs are in the queue and make it possible to run multiple jobs at the same time.

Security: there is no role based access control available in OVM Manager, if it’s needed then you have to use Oracle Enterprise Manager with the right plugin.
