We use Oracle Virtualization for Oracle products. It is compatible with Oracle, and we are compliant with Oracle. We have Hyper V from Microsoft and VMware. We chose Oracle mainly because it runs well with Oracle products. It's compatible with Oracle technology.

We have used Vmware in the past be faced challenges with supportability , compatibiollity with oracle products and licensing costs and complexity.

The product is not expensive. This support was 2000/year. If you have a very big infrastructure, it can increase because they require you to pay by the server. It becomes expensive if you have a lot of systems running on it.

I have experience with VMware ESXi and a bunch of free products, like Linux-based VMs and KVM. I did not switch from any other solutions to Oracle VM. I use Oracle VM for some special use cases.

We previously used VMware. However, I did not have the ability to use VMware in my tech environment. Since we made a contract with Oracle for our database solution and cloud services, we thought that it would be a good idea to try Oracle VM.

We chose this product because of the compatibility with other Oracle software and the ability to reduce license costs.

We did not previously use a different solution. 

For our database tier, we used proprietary hardware that worked well but we were limited to that type of hardware and it was reaching end-of-life. At the time, Oracle was adamant about their hypervisor being the only one that was license-compliant, so that took us in the direction of Oracle VM. I understand Oracle has backed away from that stance for other hypervisors, but at the time we didn’t want to double or quadruple or database licensing costs.

I also have experience with VMware. The setup for VMware is a little bit easier.

I also use IBM as per project requirements. 

we were using physical servers. then we move to VMWare but we faced issue regarding oracle apps / dbs performance. then we found OVM solution. this is best for oracle products. VMWare is also a good product but as for as performance of Oracle aap / db is concern . Oracle VM server is best option

I have worked with Hyper-V and VMware.

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.

We have a lot of customers out there that are running Oracle Database and, as we're virtualizing, there are other products out there that are not cost-efficient for the customer. Oracle VM is the logical choice there.

I've used VMware quite often, and it's an outstanding solution. It's got lots of different options, and of course, you can do things like VMotion, which allows you to move a VM in the cluster. The reason for deploying Oracle's VM is to manage the licensing, however, as we would have had to buy 10 times the number of cores if it was in a VMware cluster. That would drive up the costs.

I was using Oracle OEM and Dell Foglight on virtual machines that were already on the market. When Oracle came with its own VM product that was better suited to an Oracle environment and easy to use with Oracle builds, we switched.

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.

We used a different solution which had license limitations but Oracle VM is free and unlimited VMs can be provisioned at any time if there is adequate compute power.

I think it becomes more of a why do you use it situation. One of the things is it's a cost savings. Since Oracle VM is free and the support's free when you have Oracle hardware, you don't have to pay the expense you pay with a lot of these other hypervisor packages out there. It's an immediate cost savings out of the gate. The other times you look at what do you want to run Oracle VM is when you have performance issue. The way it works technically under the covers, the lower level of the hypervisor, the VM runs faster and I get better performance. In small environments it's nice my application runs a little faster unvirtualized. In larger environments, it's actually a bigger deal. Not only do my applications runs faster but because of the efficiency I actually have to buy less hardware.

If you compare Oracle VM vs VMware or Oracle VM vs Hyper-V, there is a definite difference in GUI. The GUI of Hyper-V and VMware are phenomenal. The GUI of Oracle VM is not that great, it is sluggish in nature, but it does everything that it is supposed to do. So, you have command line access, you have the GUI based access too, so my recommendation is to make the GUI better. It has improved in the past couple of years, and it should continue to do so.

We were previously using Oracle on HP-UX. They ceased support on HP-UX and we cut over to Linux. We needed to control our licensing costs and Oracle VM was the way to do it.

I have experience with Hyper-V, VMware, and Citrix ZenServers.

The technology is all similar. It's about virtualizing the servers. However, I feel that VMware is much better and much more stable than Oracle VM.

I also use VMware vSphere, but for Microsoft based solutions (Windows Servers, Sharepoint, MSSQL, etc). Oracle VM is a better choice and cheaper one when we are using Oracle Solutions.

We used IBM PowerVM on AIX servers. The main driver was changing the hardware. Both technologies are hardware specific. So we migrated from POWER hardware, AIX, and PowerVM to SPARC hardware, and OVM for SPARC Solaris.

I can compare triple-to-triple and none has any serious disadvantage to the other. Changing the technology was not a technical decision, but we as technical people declared that they are functionally equal.

I previously used VMware but switched because I got better support from Oracle.

We had to switch from a different solution to Oracle. We're an Oracle partner in our country. We have a sister company, which is also a partner of Oracle. Previously, we were on Citrix. It is an open-source platform.

I have prior experience with VMware, Bhyve and FreeNAS. Bhyve and FreeNAS are open-source VM solutions.

The reason we decided to invest in this new solution was all about cost. We were going with an n-tier architecture. We had 12 physical servers. Now, with the ODA, we have two chassis that run on a virtualized platform and it makes it a lot easier to manage.

In our current infrastructure, we have both ESXi and OVM Manager.

I previously used VMware products. I have found VMware vs Oracle VM to be far superior in provisioning and deployment. Additionally, there is more storage availability with VMware products. 

We also use VMware products, which I personally prefer. VMware products are an administrator's dream. They have thought of everything, including DRS, HA, templates, and virtual machine deployment. It is very easy to do all these tasks.

I have also used KVM and it is a good tool.

VMware is another good tool but it is difficult to compare them. VMware has a better hypervisor but Oracle VM does many things, and it costs less.

The company where I was used VMware solutions for virtualization of environments, and we migrated all Oracle products to an Oracle VM infrastructure.
