Hi, It does seem to me that a few of your points are overly harsh, for example you say that Oracle database is a single point of failure. It was possible to migrate the database to a RAC instance if you needed that sort of high availability however it is also important to note that the data within the database is not essential to keep your vms running and as long as you have your vm manager uuid you can recreate the metadata database from scratch, In fact this is how DR works . when you say database corruption i assume that the data in the database is inconsistent with the status of the servers. I have not seen actual corruption in the database. as you talk of Oracle XE its clear you are not on the latest version as version 3.3 and above have switched to mysql. Fromyour article it seems you are mostly using OVM to run windows boxes. we do not see issues on our linux guests when we shut thenm down even if the ha flag is enabled. Perhaps this is becasue they are pvm guest instead of hvm guests. \"a set of consultants who knew little more than us\" - were these from Oracle or did you hire them ?<\/p>\n\n

\"If you already have another VM environment (VMware, Hyper-V) you are essentially setting up a parallel VM environment to manage.\"<\/p>\n\n

That is self evident and true from any product. If you have vmware and want to creae a hyper-v environment you will have 2 products to manage. don\'t see why this was even part of your nitpick.<\/p>\n\n

We have been using OVM since 2010 for over 6 years and though we have had a couple of issues most of them were due to incompatibilties in hardware or drivers. I bet if you had used oracle hardware and storage you would have had a better experience, especially as you mention issues with EMC entry level storage and SAN disk as a single point of failure.<\/p><\/div>

I use this all the time, and have not experienced many of the problems or limitations you point out. What version were you running?<\/p><\/div>

I had tough time working on OVM environment especially on performance metrics and seems to be an immature product for Production Readiness.<\/p>\n\n

Unless you use Oracle Enterprise manager you may not be able to monitor the performance.<\/p><\/div>

I have used VMWare for virtualization. And I really feel that it is best for virtualization, when it is compared to Oracle VM and any other virtualization. Regular enhancements and good technical support makes VMWare best in market.<\/p><\/div>

Before Oracle bought Virtual Iron (Oracle\'s virtualization product), Virtual Iron was a great, up-and-coming virtualization tool. It rivaled VMWare because of the way it was priced and it worked well. I don\'t know what they have done to the product now to have such an adverse experience, especially within their own solutions. It\'s too bad for Virtual Iron and if Oracle really appreciated what they own, they would have developed this tool even further beyond their own solutions. VMWare is the industry standard for server virtualization.<\/p><\/div>

We used HP hardware, not provided by Oracle but in their compatibility matrix. I find that IBM and HP do a better job of standing behind their product than Dell, which tends to point fingers at their OEMs. However, it has been several years since I have dealt with a new Dell server, so that may have changed.<\/p>\n\n

I only have direct experience with VMware and Oracle VM, so I would have to say VMware. It is definitely the most robust and mature virtualization product. I understand Hyper-V has improved over the years but I haven\'t had the opportunity to try it.<\/p><\/div>
