project release , which serves as a free and open-source alternative to the proprietary platform for deploying and managing cloud infrastructure. XCP-NG reproduces , which Citrix removed from the free version of Citrix Xen Server starting from version . XCP-NG 8.0 is positioned as a stable release suitable for widespread use. Upgrade from XenServer to XCP-ng is supported, ensuring full compatibility with Xen Orchestra and allowing the migration of virtual machines between XenServer and XCP-ng and vice versa. For downloading the installation image, which is 520 MB in size.
Like XenServer, the XCP-NG project allows for quick deployment of virtualization systems for servers and workstations, offering tools for centralized management of an unlimited number of servers and virtual machines. Features of the system include the ability to cluster multiple servers into a pool, high availability support, snapshot capabilities, and shared resource usage through XenMotion technology. Live migration of virtual machines between cluster hosts and between different clusters/individual hosts (without shared storage) is also supported, as well as live migration of VM disks between storages. The platform can work with a large number of storage systems and features a simple and intuitive interface for installation and administration.
Key innovations:
- Packages for using the ZFS file system for storage repositories have been added to the main repository. The implementation is based on the ZFS On Linux 0.8.1 release. To install, simply execute "yum install zfs";
- Support for ext4 and xfs for local storage repositories (SR, Storage Repository) remains experimental (requires installation of "yum install sm-additional-drivers"), although no reports of issues have been submitted so far;
- Support for booting guest systems in UEFI mode has been implemented;
- A mode for rapid deployment of Xen Orchestra directly from the basic host environment interface has been added;
- The installation images have been updated to the CentOS 7.5 package base. The Linux kernel 4.19 and the hypervisor are now used ;
- Emu-manager has been completely rewritten in C;
- There is now the ability to create yum mirrors, which are selected based on location. In net-install, a check of the downloaded RPM packages by digital signature has been implemented;
- By default, dom0 includes the installation of the cryptsetup, htop, iftop, and yum-utils packages.
- Added protection against attacks (Microarchitectural Data Sampling) on Intel processors.
