Oracle VM Reviews

Feature-wise, the solution's high availability to most servers is good. The virtual sellers don't have a host. I think that one is the most valuable for me.

I know they moved from OVM, and I think right now, they are moving into KVM or something else. I don't have much to say about the improvement if they are already shifted to the KVM.

The configuration can be more flexible. It is a necessity.

I have been using Oracle VM since 2014. Also, I am not using the solution's latest version. I am using Oracle VM 3.4. I am a customer of the solution.

Stability-wise, I rate the solution a ten out of ten.

Scalability-wise, I rate the solution a ten out of ten.

Right now, no one in my company uses the solution.

I rate the solution's technical support a ten out of ten. I have used their support, and it is good.

Positive

On a scale of one to ten, where one being difficult and ten being easy, I rate the setup a five because the vendor was supposed to have done the biggest part, and they actually don't configure everything.

The deployment was done in a week or two.

Three people, along with the vendor, were needed for deployment.

The solution's UI is good enough.

I rate the overall solution a ten out of ten.

It offers live migration. It is the best virtualization option for Oracle databases for Linux as Oracle recognizes hard partitions for their database licensing.

If you need to put an Oracle Database on Linux or Windows for any reason, and don't want to pay to license a whole VMware cluster, this is the next best option.

There are several VMware features missing. I haven't done an in-depth analysis to understand which exact ones they are.

I've been using it for three years.

There were no issues with the deployment.

Stability was great. There were no issues with instability.

I only deployed it to a small, three-node Oracle X5-2 cluster.

Never had to open an SR. It's pretty stable. I did create ask some fairly technical questions about it on the My Oracle Support Community and got some great help there.

We previously used VMware which we had to use for licensing reasons, and to be able to own the full stack (hardware/virtualization/OS). My team had minimal permissions on the VMware side.

It was fairly easy for an experienced Linux admin.

I did the implementation myself.

I never did an ROI calculation.

It's much cheaper than paying millions for Oracle DB in VMware. Support for Oracle VM and Oracle Linux are included when installed on Oracle hardware, which makes it a very cheap option. There is a free, unsupported version available too. That might be attractive to some.

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.

I have been working with Oracle VM for around ten years. So far, it has been working well. 

If you don't have any issues, it works perfectly. If you do encounter issues, there aren't many. But where there are some issues, it can be a little more challenging compared to other solutions I've worked with. However, I understand it better now as we are transitioning to the latest utilization from Oracle, which they use in their cloud.

I would rate the stability of Oracle VM a nine out of ten. We haven't encountered any issues while working in production. 

However, if there are any issues, it's important that the environment supports optimal utilization. Additionally, it's worth noting that we are using an older version of the Oracle server. We are currently in the process of installing it in a new data center.

It is a scalable solution. The new version is more scalable than the old one.

Overall, I am happy with Oracle's support.

Positive

I work with the paid version. We are moving to the latest Oracle virtualization solutions, so we are going to stick to this solution.

Overall, I would rate Oracle VM an eight out of ten. 

Our customers use the solution for database and service applications.

The solution's most valuable feature is live migration.

The solution's management, hardware, and backup recovery features could be better.

Our customers have been using the solution for four years.

We have ten solution users in our organization. They include system administrators.

The solution's technical support is quite good.

Positive

The solution's initial setup process is easy.

The solution's price is relatively low.

I rate the solution a seven. I advise others to go for Oracle Linux Virtualization Manager, the next platform for Oracle based on KVM.

The main use case of this solution is integration. The integration of the database and compatibility with the affiliate in terms of license management. This will reduce the cost of the license.

It is the same use case as vSan except that you can partition the applications and it forces you to license the processor, as opposed to the server.

I would like to simplify the processes to implement. When you want to implement Oracle, the steps that you perform could be simplified.

The usage could be easier, and more user-friendly.

I have been using Oracle VM for a few months, we started using it in November.

We are using version 3.4.

It's quite stable.

We have 10 users in our organization. It's a new product.

We are still in the testing phase. We are looking forward to observing its behavior. If it behaves well and there are no major incidents that give us or the support team issues, we will continue to plan ahead and implement it.

Technical support could be faster.

It is very difficult to implement.

It is not user-friendly, so you need a bit of skill to deploy it.

When compared to other solutions, it is quite complex. The complexity depends on the individual environment.

For the deployment, you need a consultant and an integrator. It is very difficult to deploy this solution. If you use the server storage, you need a consultant.

Oracle VM is inexpensive. It's open-source, but you pay for support.

Oracle is free of charge, although you have to have a subscription for the support.

Currently, they are trying to improve this solution database and technology. They are trying to upgrade it to make it a more customizable database.

I would certainly recommend this solution to other users who have Oracle applications. It has been customized to optimize this database.

I would rate Oracle VM a nine out of ten.

We are building a private cloud with Oracle VM. We want to implement Oracle RAC with Clusterware releases 12.2 and 18c, and with Oracle Database releases 11.2.0.4 to 18c.

We will implement a full dev/test environment with Oracle RAC and standalone databases. We will be able to fully use our ULA license agreement with Oracle and provide flexibility to our development teams.

Oracle virtual machine templates for rapid deployment are very useful. This allows us to deploy already-implemented and optimized virtual machines.

Snapshotting could be easier. And there could be more intuitive ways for cloning of virtual machines.

When deploying the Oracle database, you can license only the processors used for the database rather than all the processors on the box, as with VMWare. Plus, it’s free.

We are able to build large hosts (using Oracle Virtual Cloud Appliance, for example) and wait to license CPUs for our databases until we need them. That translates into more money up front for servers and salespeople.

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.

I've been using it for three years.

It’s a bit clunkier to deploy and manage than other systems, e.g. VMware.

We have had no stability issues.

Scalability has not been an issues.

Oracle is very good at supporting engineered systems, so if you’re using OVM on a PCA, you get good service. Otherwise, it’s pretty typical tier-one/tier-two tech support.

I have used VMware, Hyper-V, and AIX LPARs. I chose Oracle VM (when using x86) not only because it’s free, but because of the Oracle DB licensing benefits. Hyper-V is not really all there yet. VMware is awesome, but the Oracle licensing is a crippling problem.

I would say it’s less straightforward than you’d expect. I haven’t installed it recently, but my impression was that it was about 70% ready for prime-time. Once you have it installed and sorted out, it runs pretty smoothly. Getting it there is another issue entirely.

We mostly use a vendor to set up OVM, but occasionally we will do it in-house as well. My main advice is to practice it first, read all documentation, look at MOS documents, and review all blogs and community discussions you can find.

For our specific ROI, OVM allows us to buy larger systems to accommodate projected growth but not go broke on licensing. We can get new licenses on demand when we have a reason to buy them rather than all up front and hoping we expand into it. That means we can concentrate on selling new opportunities and buying the licenses after the sales are locked in. We don’t have money sitting out there idling.

The biggest benefit is being able to license Oracle products (especially the DB) based on the number of CPUs actually used rather than all the CPUs on the box as you have to do with VMware. This results in a lot more flexibility in the sizes of servers you can buy and how you plan for future growth. If you had to buy all Oracle licenses for every CPU, you might get a smaller server to start with and that doesn’t really help with expansion.

Properly sizing your equipment for growth often means buying equipment much larger than you need right away. The money you save with Oracle VM by not buying extra licenses means you can focus on preparing your hardware for the future rather than having to balance between licenses, hardware, and practicality.

Before speccing out your systems, it’s best to start figuring out how many CPUs you need now and in the future, then you’ll be able to decide what server/VM solution you need. If you’re looking at a small software footprint now, but in one to two years you expect to double or triple your transactions, you’ll definitely want to start with a big server and OVM to reduce software licensing costs.

My main advice is not to do your first install when sitting at the client building a production system. Practice it beforehand and make sure you work the bugs out. Once you install it the first time, it’ll be far easier to breeze through it on subsequent installs.

The big benefits to Oracle VM that I see in users that I work with are, first of all, performance. You don’t have what I call the "virtualization tax" like you do on other hypervisors. The CPU that you buy actually becomes more and more useful. You don’t have all that overhead. You get really good disk performance, almost comparable to bare metal when you configure it correctly. That’s an important feature for people that are using it. 

Overall, the biggest performance is around virtualization and automation, you can build private clouds with Oracle VM using Enterprise Manager.

Oracle VM is a great free product from Oracle. I love that, when I can say "free from Oracle." It’s a full feature hypervisor. It competes well with other hypervisors in the market. However, it’s free. You don’t pay anything to use it. You can, however, pay for support if you need support. 

It offers all the features you expect in a hypervisor, using technologies that they call Live Migration. It allows me to move VMs from one machine to another. I have a technology called Site Guard which is an automation tool for automating failover to disaster recovery sites. Feature for feature, it does almost everything VMware does but cost a lot less.

One is the hypervisor. Right now, it’s all using Xen. What would be really helpful is to have some choice, and the underlying hypervisor technology use KVM which is very popular with certain workloads. 

There are also some features around it, extracting virtual machines and managing it, that could show some improvement.

There’s still some area for improvement with some of the newer technologies.

It’s actually very stable. In the later releases, you can even patch the hypervisor without a reboot. That adds to the up-time of the environment. When you run Oracle Linux inside as guest VMs, you can also use the Ksplice technology and patch the VMs without any outage.

Scaling in Oracle VM is an interesting prospect because you have two ways you can scale it. You can, first of all, use really, really big hosts with large numbers of CPUs. Four-socket, eight-socket CPUs are fully supported with it. But you could also scale it with a large number of servers in the environment, so you can scale horizontally and vertically. I have not had any issues with the scalability of Oracle VM. It scales really well.

Setting up Oracle VM depends on what you want to do with it. If you want to do a basic install and use the normal management console, I’ve done that in a couple of hours. I’m experienced with it. 

But if you want to build private clouds with it, you want to interface the Enterprise Manager, have chargeback functionality for users, you want to do cloud automation; that’s a little more complicated. If you haven’t done it, it takes about a week. However, there’s a book from Oracle Press about Oracle VM 3 and building private clouds, and that helps a lot with what's involved in this task, to build and support a system.
