It is now possible to modify certain boot parameters without the need to reboot Xen. The Xen Project community also made significant changes to the hypervisor’s user interface.
Tagr 4.10.0 driver#
The PV Calls backend driver was added to Linux 4.14.īetter User Experience through the Xen Project User Interface This enables a new networking model that is a natural fit for cloud-native apps.
Tagr 4.10.0 drivers#
PV Calls Drivers in Linux: In Xen Project 4.9, the Xen Project introduced the PV Calls ABI, which allows forwarding POSIX requests across guests. For more information on alt2pm is available here.
Tagr 4.10.0 software#
A software page table walker was added to VMI on ARM, which lays the groundwork to alt2pm for ARM CPUs. Virtual Machine Introspection improvements: Performance improvements have been made to VMI. Soft affinity adds a flexible way to express placement preference of vcpus on processors, which improves cache and memory performance when configured appropriately. Added tracing support enables users to optimise workloads and introduced soft-affinity. Null scheduler improvements: The recent updates to the “null” scheduler guarantee near zero scheduling overhead, significantly lower latency, and more predictable performance. In addition we added cap support allowing users to set a the maximum amount of CPU a VM will be able to consume, even if the host system has idle CPU cycles.
This enables NUMA aware scheduling for the Credit 2 scheduler. He is a virtualization kernel developer at Suse and maintainer of Xen subsystem in Linux as well as parvirtualization.Ĭredit 2 scheduler improvements: Soft-affinity support for the Credit 2 scheduler was added to allow those using the Xen Project in the cloud and server space to specify a preference for running a VM on a specific CPU. Jürgen has been an active developer for the past few years, making significant code contributions to advance Xen support in Linux. We are also pleased to announce that Jürgen Groß will be the next release manager for Xen Project Hypervisor 4.11. The release is equipped with the latest hardware updates from Arm and a more intuitive user interface. The Xen Project Hypervisor 4.10 continues to take a security-first approach with improved architecture and more centralized documentation. As always, we focused on improving code quality, security hardening as well as enabling new features. I am pleased to announce the release of the Xen Project Hypervisor 4.10. De ontwikkelaars hebben versie 4.10.0 uitgebracht met de volgende aankondiging: What’s New in the Xen Project Hypervisor 4.10 Op dit moment worden alleen Linux, NetBSD en FreeBSD als hostsystemen ondersteund, maar men is druk bezig om ook andere besturingssystemen volledig te ondersteunen.
Voor meer informatie over Xen en de bijbehorende community verwijzen we naar deze en deze pagina. Xen is een baremetal-hypervisor voor het x86- en ARMv7/v8-platform, en laat diverse besturingssystemen gelijktijdig op één systeem draaien zonder de prestaties drastisch te beïnvloeden.
