project release , which develops a free and free replacement for the proprietary Citrix Hypervisor platform (formerly called XenServer) for deploying and managing the operation of cloud infrastructure. XCP-NG recreates , which Citrix has excluded from the free Citrix Hypervisor/Xen Server variant since version . Upgrading Citrix Hypervisor to XCP-ng is supported, full compatibility with Xen Orchestra is provided, and the ability to move virtual machines from Citrix Hypervisor to XCP-ng and vice versa. For loading 600 MB installation image.
XCP-NG allows you to quickly deploy a virtualization system for servers and workstations, offering tools for centralized management of an unlimited number of servers and virtual machines. Among the features of the system: the ability to combine multiple servers into a pool (cluster), high availability tools (High Availability), support for snapshots, sharing shared resources using XenMotion technology. Supports live migration of virtual machines between cluster hosts and between different clusters/individual hosts (without shared storage), as well as live migration of VM disks between storages. The platform can work with a large number of storage systems and is distinguished by the presence of a simple and intuitive interface for installation and administration.
The new release not only recreates the functionality , but also offers some improvements:
- The installation images of the new release are built on a CentOS 7.5 package base using a hypervisor . Added the ability to use an alternative Linux kernel based on the 4.19 branch;
- Stabilized support for booting guest systems in UEFI mode (Support for Secure Boot is not transferred from Citrix Hypervisor, but created from scratch to avoid intersections with proprietary code);
- Added support for XAPI add-ons (XenServer/XCP-ng API) needed to back up virtual machines by capturing a slice of the contents of their RAM. Users were able to restore the VM along with the execution context and the state of the RAM at the time of the backup, similar to restoring the system state after waking up from hibernation (the VM is suspended before the backup);
- Improvements have been made to the installer, which now offers two installation options: BIOS and UEFI. The former can be used as a fallback on systems that are experiencing UEFI issues (such as those based on AMD Ryzen CPUs). The second one uses the alternative Linux kernel (4.19) by default;
- Improved performance for importing and exporting virtual machines in XVA format. Improved storage performance;
- Added new I/O drivers for Windows;
- Added support for AMD EPYC 7xx2(P) chips;
- chrony is involved instead of ntpd;
- Deprecated support for guest systems in PV mode;
- New local storages now use the Ext4 FS by default;
- Added experimental support for building local storages based on the XFS file system (requires installation of the sm-additional-drivers package);
- The experimental module for ZFS has been updated to version 0.8.2.
