Room For Improvement

Citrix XenServer users criticize limited Linux support, insufficient backups, high cost, and inadequate performance in free high-availability features.
Oracle VM users seek improvements in UI, integration, documentation, and features like drag-and-drop, backup, and monitoring tools.
Although the product is technically competitive, it is not widely known or used due to poor marketing.
Citrix needs to improve the hypervisor, specifically in security and performance.
We can implement high availability and live migration with pools, along with security and backup to enable role-based access control for safer management.
If I have limited systems and there is maintenance on the hardware, the Oracle systems are impacted.
Not every upgrade goes smoothly, and after an upgrade, it sometimes stops working.
Oracle VM provides automation capabilities in the new version.

Oracle VM offers scalable, secure, open-source virtualization with extensive automation, cost savings, and enhanced compatibility with Oracle databases.

It provides secure access to applications and resources, which is crucial for us and our clients.
It is user-friendly and easy to deploy, making it an attractive option.
If there is an issue with the operating system running on top of it, there's no primary and secondary domain, rather segregated I/Os, disks, memory, everything assigned to a logical domain.
It is easy to copy or clone one Oracle workstation to another.

Featured Reviews

Jörg Köhler - PeerSpot reviewer
Consulting benefits from robust consulting while also recognizing the need for improved disk management
When it comes to optimization, that's one of the weaker points of Citrix XenServer, especially regarding disk management, which is somewhat clumsy. Backup-related issues and disk management should be improved. Especially concerning backup, as discussions with Veeam engineers about Citrix XenServer backup strategy indicate there might not be a solution from Veeam soon. License optimization is not such a significant problem, but licenses are quite complicated. Vendors constantly invent new license models, making it difficult to order the correct licenses needed. There is not a big difference between Citrix and VMware products because Citrix can implement Windows and Linux anyway.
