Grub2 on Xen PV
Hi, Let me start a new thread for this. I contacted the Grub people, and they seem more interested in creating a native Xen port of Grub than piggybacking the Mini-OS environment usin kexec as I tried. But they need some documentation on the Xen "firmware" to assess the task at least. What could be given to them apart from hvc_xen.c and xen-blkfront.c in the Linux sources?

[PATCH] minios: Fix xenbus_rm() calls in frontend drivers
From: Ben Cressey <bcressey@amazon.com> The commit "minios: refactor xenbus state machine" caused "/state" to be appended to the local value of nodename. Previously the nodename variable pointed to dev->nodename. The xenbus_rm() calls were not updated to reflect this change, and refer to paths that do not exist. For example, shutdown_blkfront() for vbd 2049 would

stubdom questions
samuel, I have a try with HVM stubdomain on r17062, but failed to make on 32b platform. Attached patch can fix it, but don''t know if okay. After installation, I failed to start stubdom. So I created it manually and got following debug mesg(both HVMdomain and stubdom are created) Can you give some lights on following questions: 1. I use default vnclisten. Does it matter? 2.

[PATCH] xen/pvhvm: If xen_platform_pci=0 is set don''t blow up.
The user has the option of disabling the platform driver: 00:02.0 Unassigned class [ff80]: XenSource, Inc. Xen Platform Device (rev 01) which is used to unplug the emulated drivers (IDE, Realtek 8169, etc) and allow the PV drivers to take over. If the user wishes to disable that they can set: xen_platform_pci=0 (in the guest config file) or xen_emul_unplug=never (on the Linux command

Xen Roadmap proposal
Folks, Please find attached a proposal for the Xen development roadmap for the next 18 months or so. The roadmap gives a "state of the nation" summary and provides suggestions as to priorities going forward. I''ve tried to be inclusive and collect together many of the various features that folks have asked for, along with some implementation ideas to guide developers. The

[PATCH] xen: initialize platform_pci even if xen_emul_unplug=never
When xen_emul_unplug=never is specified on kernel command line reading files from /sys/hypervisor is broken (returns -EBUSY). It is caused by xen_bus dependency on platform_pci and platform_pci isn''t initialized when xen_emul_unplug=never is specified. Fix it by allowing platform_pcii to ignore xen_emul_unplug=never, and do not intialize xen_[blk|net]front instead. Signed-off-by: Igor

Mini-OS: new_pt_frame fails
Hello, as some might have read in my previous postings, I have a Mini-OS dom0 that constructs a Mini-OS domU on x86 xen-3.0.4-testing. As the memory layout my Dom0 builds does not guarantee, that pages the DomU Mini-OS tries to use as page tables are mapped to existing memory, I changed new_pt_frame in arch/x86/mm.c in the following way: The pt_pfn is mapped R/W, then it is zeroed by a

minios, use of namespace
For a while I''ve been intending to provide a better environment for PV baremetal guests. The current arrangements, based on newlib, take quite a bit of porting for many programs. My plan is to take the FreeBSD libc, and write a set of functions implementing the "system calls" in terms of facilities provided by the Xen PV environment, frontend drivers, etc. As part of this I

[PATCH 0 of 4] Minios improvements for app development
This patch series contains a set of patches making minios rather easier to use, from an application development point of view. Overview of patches: 1 Command line argument parsing support, from Xen. 2 Weak console handler function. 3 Build system tweaks for application directories. 4 Trailing whitespace cleanup. (because it is very messy) Patch 4 is likely to be more controversial than

[PATCH] remove the xen dracut module
The Xen module is unnecessary and it has been for a while. Most Xen systems will not be using the module, even now, because xen-detect is not installed by default on most Xen systems, and dracut uses xen-detect to decide whether to include the module. It also has some problems: 1) it does not try loading xen_platform_pci; 2) it loads modules unnecessarily; modules.alias is where all Xen
