Xen at Silicon Valley Linux User Group

By July 15, 2011March 7th, 2019Announcements

Stefano Stabellini, one ouf our Xen maintainers will talk about Xen Support in the Linux Kernel: Upstreaming Efforts and New Developments at the Augst  SVLUG meeting. The SVLUG meeting is held in Mountain View, Aug 3 from 7-9 PM at the Symantec Offices. See you there!
Xen reuses many externals of open source projects, Qemu and Linux in particular. During the first years of existence, Xen accumulated a large number of changes to these external projects, but then struggled to upstream them. In the last couple of years, the Xen community has been removing dependencies on downstream modifications, and establish better relationships with other open source communities. What is the current status of Xen in relation with other free software projects?
At the same time, Xen development proceeded at a fast pace, and several new features were introduced; this talk will go through one in particular: PV on HVM support in the Linux kernel. Traditionally, Linux has always run on Xen either as a pure PV guest or as a virtualization- unaware guest in an HVM domain. Under the name “PV on HVM”, work has been done to make Linux aware that is running on Xen, and enable as many PV interfaces as possible, even when running in an HVM container.
