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_unplu...

...le to install arbitrary HVM images. We want both PV and emulated drivers to appear. The reason for this is for compatibility with images that were prepared for Xen 3.3, which assume emulated devices exist at boot time (particularly for running the boot loader). If I do not specify on the boot line xen_emul_unplug=never, then under some guest OS''s (e.g. Ubuntu Natty (2.6.38)), the domU kernel unplugs the non-PV devices, which is undesirable in my application. I cannot arbitrarily change the kernel command line because it is in effect set by the user''s image. Therefore what I need to do is...

...iver: 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 line) except it does not work properly. The PV drivers still try to load and since the Xen platform driver is not run - and it has not initialized the grant tables, most of the PV drivers stumble upon: input: Xen Virtual Keyboard as /devices/virtual/input/input5 inpu...

Hi Linus, These patches make it possible to inhibit the Xen emulated device unplug on the kernel command line (mostly "Just In Case") and renames xen_emul_unplug=ignore to the clearer xen_emul_unplug=unnecessary. Since it changes the name of a command line option we''d like to get it in before 2.6.36 proper. The third changeset is a pure cleanup which you could ignore for 2.6.36 if you wanted. I can resend without if you prefer. Ian. The followi...

Hi! I tried booting ubuntu natty/oneiric domUs with 2.6.39 and 3.0rc1 linux-image packages, but they all "just stop" after the kernel is loaded and the init process should take over. The problem must be within the linux-image package, since natty domUs with the standard 2.6.38 kernel boot just fine. I also have debian and gentoo domUs running 2.6.39 without issues, so it''s

Hi Konrad, I just tried linux-3.4-rc0 (linus his tree, last commit f52b69f86e27903d6896ed5fa7cd280fec8de532) with 3 additional branches from your tree pulled on top of that: branch stable/for-ingo-3.4.v2 (required for dom0 to boot) branch stable/for-jens-3.4 branch stable/for-jens-3.4-bugfixes Hypervisor is xen-4.1.3-rc1-pre linux 3.3 vanilla works fine Booting dom0 goes fine, but

Hi- I am trying to pass an LSI SAS2008-based HBA (IBM M1015) through to an HVM Solaris VM, using Xen 4.2 unstable and the qemu-traditional device model. On boot I see the following error: MPT BIOS Fault 09h encountered at adapter PCI(00h,05h,00h) A list search yielded (http://comments.gmane.org/gmane.comp.emulators.xen.devel/128172), however there was no solution for an HVM VM. I''ve

In the past I have used clonzilla under xen to backup windows domains. I just tried it and it will not work. this is xen 4.1.2 and clonzilla-live 1.2.10-14 the disk line is: disk = [ ''phy:/dev/xvg0/nfdlts-c,hda,w'', ''file:/extra/isoimages/clonzilla.iso,hdc:cdrom,r'' ] It boots cd OK. The problem is devices are xvda not hda and clonzilla is not happy with

Hello, I''m currently trying to understand some problems I had in the past with mixing look-back with blktap(2) for HV and PV domains. I''m stuck reading the source code, so I''d like to get some help from the list. Interrupt me if I got something fundamentally wrong in my understanding so far: 1. With pure-HV the domU gets an emulated IDE (or whatever) disk. The

Moving to public discussion... This was found with Xen hypervisor version supporting device unplugging and the domU kernel having net-/blkfront and pci platform built-in (or as module). The block device is defined as hda and the NIC type=ioemu (so theoretically guests without pv support would work, too). Since both drivers are present, the kernel tries to unplug the emulated devices and
