Well, the mainline kernel just hit 2.6.27-rc1, so it's time for an update about what's new with Xen. I'm trying to aim this at both the user and developer audiences, so bear with me if I seem to be waffling about something irrelevant. 2.6.26 was mostly a bugfix update compared with 2.6.25, with a few small issues fixed up. Feature-wise, it supports 32-bit domU with the core devices

From: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Hi all, This series adds a new microcode driver for Xen. The Xen hypervisor can deal with all the low-level details of doing a microcode update (Intel vs AMD, doing all the physical CPUs present on the system, current and future, etc), so all the driver has to do is make a hypercall to upload the microcode into Xen. This only

I''ve been trying for several days to get a xen dom0 booting as described on Boris Derzhavets blog. I have been able to boot Jeremy Fitzhardinge''s pv_ops kernel under xen, but my X server wouldn''t start so I''ve been trying to get Andrew Lyon''s rebased opensuse patches to work. I have asked for help in the freenode ##xen channel but they

Hi Ingo, Here''s the chunk of patches to add Xen Dom0 support (it''s probably worth creating a new xen/dom0 topic branch for it). A dom0 Xen domain is basically the same as a normal domU domain, but it has extra privileges to directly access hardware. There are two issues to deal with: - translating to and from the domain''s pseudo-physical addresses and real machine

Hi all, I've been looking at the next steps to try to get Xen running fully on top of pv_ops. To that end, I've (just) started looking at one of the next major jobs --- i686 dom0 on pv_ops. There are still a number of things needing done to reach parity with xen-unstable: x86_64 xen on pv_ops Paravirt framebuffer/keyboard CPU hotplug Balloon kexec driver domains but it

Hello. log of the crashing boot process: http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-bootlog-14-xen331-linux-2.6.29-rc6-crash.txt 2.6.29-rc5 based pv_ops dom0 works on the same computer.. with the same Xen version. I tried with and without pci=nomsi. adding ''noapic'' doesn''t seem to help (I need that with 2.6.29-rc5 to make it work). Any ideas

Hi, Im trying to install Netware and Windows 2008 server but im having problems with it reading the ISO. Im guessing this is because im running version 3.2.1 debian packages so i want to upgrade to unstable and use the 3.4 deb packages. My problem is that there isn''t a kernel package so when booting you cant boot into xenified kernel mode. If i try and use a kernel from the

Hi folks, I've finished off Xen dma support for pv_ops, and dom0 now boots! I've had an uptime of 40 minutes so far with it. Under intensive disk load it locks up with a soft lockup, but still, this is good progress. I've pushed the current bits to the "WIP" (work-in-progress) branch at the usual git repo, git://et.redhat.com/linux-2.6-dom0-pvops.git with gitweb at

I''m currently working on moving storage services into their own domain and I''ve been looking at blktap2. I''ve been trying to get an image mounted with blktap2 and for some odd reason and tapdisk2 keeps hanging instead of quitting at the end. I haven''t removed any of the storage startup code at this point so everything should be as it normally is in xen-unstable.

Hi, I found latest pv_ops dom0, commit 3dd81018a392941fcc722ee521de344527481eb8, fails to boot with call trace. And commit 34ffcd2bde0018cf78d5b4f1f5427c38a3e9b502 has no such issue. Could anyone help on this issue?

Hi, On paravirt x86 (both 32- and 64-bit), since cset 13998: http://xenbits.xensource.com/xen-unstable.hg?rev/13998 we translate all ptes from being mfn-based to pfn-based when the hardware _PAGE_PRESENT bit is cleared. We do this for PROT_NONE pages, which appear to the HV to be non-present, but which are special-cased in the kernel to appear present (a different bit in the

Hello, I seem to be having some troubles regarding the latest 2.6.31.6 and 2.6.32.9 Xen dom0 pv_ops trees. Our platform: -Xen 3.4.3-rc3 (also tried 3.4.2 on 2.6.31.6 pv_ops dom0) -2.6.32.9 pv_ops dom0 kernel, perhaps a week old checkout from xen/stable git (can provide changeset if requested). -100+ domU''s, all PV. Ever since we switched to a pv_ops dom0 kernel (we were using 2.6.26
