similar to: Xen 4.4 development update: RC0 imminent

This information will be mirrored on the Xen 4.4 Roadmap wiki page: http://wiki.xen.org/wiki/Xen_Roadmap/4.4 Our timeline had us start the code freeze last Friday. However, we have not released an RC0 because we have been waiting for PVH dom0 support. Adding bug fixes during RCs makes sense, but RC0 should contain all of the functionality we expect to be in the final release. PVH dom0 support

This small series reintroduces OVMF support in Xen You can fetch working OVMF tree on: git://xenbits.xen.org/people/liuw/ovmf.git master Working changeset that can be sticked in Config.mk is: 8833370303d3bf3153760ee42760ef1b9b5c562 Note that VNC doesn''t work properly when using OVMF, but that''s not OVMF''s problem. This issue should be addressed in Xen and I''m

There are basically three issues we''re waiting to sort out (see below for more info): * XSA-55 * cpu hotplug in qemu-upsream * The MMIO hole issue Unfortuantely, there is considerable uncertainty about how long it will take for each of those to complete. We''re hoping to be able to release maybe on the 19th, This information will be mirrored on the Xen 4.3 Roadmap wiki page:

Hi all, I was messing around with kexec and it seems to work just fine on KVM, but for Xen domU images, it doesn't work at all. Daniel, I saw some patches from you back in September 2012 for adding this support for Dom0, but they don't seem to have gone into the kernel (but other patches went into kexec-tools at that time.) You mention that domU support is "easy" after your

The aim of this patch is to define a stable way in which PVH is going to do AP bringup. Since we are running inside of a HVM container, PVH should only need to set flags, cr3 and user_regs in order to bring up a vCPU, the rest can be set once the vCPU is started using the bare metal methods. Additionally, the guest can also set cr0 and cr4, and those values will be appended to the default values

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

Hey all, We've been on 4.9 for some time now, and while it's still supported, I think it's time to start thinking about upgrading, and I'd like input from the community about which version to move up to. 4.19 has been out for almost 5 months now. It will include PVH domU support, and PVH dom0 support in what _is believed_ to be the final form; so when the Virt SIG moves to a

George, since you asked on Friday, I though about the situation some more over the weekend. On PV, the requirement to trap all INs and OUTs is a result from us needing the enforce two levels of restrictions - Xen''s and the guest kernel''s. I.e. we can''t make use of the hardware''s access control mechanisms, as we can''t put two I/O bit maps in place, and

Hello everyone! With the completion of our first few release candidates for 4.2, it''s time to look forward and start planning for the 4.3 release. I''ve volunteered to step up and help coordinate the release for this cycle. The 4.2 release cycle this time has been nearly a year and a half. One of the problems with having such a long release is that people who get in features

Hi Debian Grub maintainer, In december, Xen PVH support has been committed in grub master: https://www.mail-archive.com/grub-devel at gnu.org/msg28125.html The last pieces needed in the Linux kernel to boot PVH with grub2 landed in Linux 4.20. I asked our kernel team to carry those patches on top of the Linux 4.19 kernel that is going to ship in Buster, and that wish was granted:

Some firmware, such as OVMF relies on this value to get the size of extra memory above 4GB. Seabios in Xen doesn''t need this as it gets e820 directly from Xen. Rombios doesn''t read this value.

This is problem 1 of 3 problems we are having with live migration and/or ACPI on Xen-4.3 and Xen-4.2. Any help would be appreciated. Detailed description of problem: We are using Xen-4.3-rc1 with dom0 running Ubuntu Precise and 3.5.0-23-generic kernel, and domU running Ubuntu Precise (12.04) cloud images running 3.2.0-39-virtual. We are using the xl.conf below on qemu-upstream-dm and HVM and
