similar to: domU can not start in Xen 4.0.1-rc3-pre using tapdisk

I''m getting this message (subject line) in daemon.log every time I start or restart xend. I''m not sure if this is related to the fact that I cannot boot up my Windows domU from a VHD file. The Windows domU was working fine with Xen 4.0.0 (with 2.6.32.14 dom0 kernel). When I upgraded to Xen 4.0.1-rc4 (with 2.6.32.16 dom0 kernel), I can no long boot the Windows domU from VHD. The

Hi All, I''m having a similar issue as Ian Tobin some weeks ago here: http://lists.xensource.com/archives/html/xen-users/2010-02/msg00645.html I''m using Debian Squeeze amd64, downloaded the experimental debian xen-amd64 kernel with pv_ops support. linux-headers-2.6.32-5-common-xen_2.6.32-13_amd64.deb linux-headers-2.6.32-5-xen-amd64_2.6.32-13_amd64.deb

Hello List If i have a PCI=[08:00.0](example) in any DomU config file the xm shutdown <ID> shuts down this DomU and the Dom0! Otherwise i shutdown this DomU from inside the DomU with halt or shutdown -r now, the Dom0 shuts down to. This happend on Xen 3.4.2 and Xen 4.0 (Kernel 2.6.18.8-xen, 2.6.18.8-xen0) The Operating System to Compile xen was Debian Lenny and the Dom0 os. Without

I''m newbie Xen-4.1.1 I''m trying to boot DomU with the following configuration. Sometime DomU boot, but sometime boot failed I''m not sure what is the problem. I can attach that image with tap-ctl on Dom0. Does anybody advice me about this problem?? Sincerely * Environment OS : Scientific Linux 6.1 x86_64 Kernel : 2.6.32.43

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

Hi, I''ve been testing Xen 4.0.1 with kernel 2.6.34.5 + http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.34-4.tar.bz2, and one of the things that I noticed immediately is there are two problems with tapdisk and this combination. First, the syntax "disk = [''tap:tapdisk:aio: ..." no longer works. When tested with HVM domU, it boots, but there was no disk

Hello, I have been playing around with Remus on Xen 4.0.1, attempting to fail-over for an HVM domU. I''ve run into some problems that I think could be related to tapdisk2 and its interaction with how one sets up Remus disk replication in the domU config file. A few things I''ve noticed: -The tap:remus:backupHostIP:port|aio:imagePath notation does not work for me, although this

There seems to be an outdated page to use PV drivers here: http://wiki.xensource.com/xenwiki/XenWindowsGplPv I''d be great if that could be updated. After installing the PV drivers in windows I didn''t notice any difference in performance at all. Windows says the drivers are working. Some more searching and reading and it appears that I do actually need to make some changes to

I have tried 4 time unsuccessfully to install Xen 4 on Ubuntu Lucid (10.4) 64 bit version using the tutorial at http://bderzhavets.wordpress.com/2010/04/24/set-up-ubuntu-10-04-server-pv-domu-at-xen-4-0-dom0-pvops-2-6-32-10-kernel-dom0-on-top-of-ubuntu-10-04-server/ on a Lenovo thinkcentre workstation.

Hi all, I try to use kernel 2.6.36.1 in HVM but building the drivers xen-blkfront, xenfs, platform-pci. I used Xen 4.0.2-rc1-pre and a DomU is a ubuntu 10.04 and I try with ubuntu 10.10. In boot I receive error "Cannot find a root partition /dev/xvda2" and a prompt (initramfs) appear. In dmesg (initramfs) appear: blkfront: xvda: barriers enabled (tag) xvda: xvda1 vbd vbd-51712: 16

Hi, I''ve been working on getting a working blktap driver allowing to access ceph RBD block devices without relying on the RBD kernel driver and it finally got to a point where, it works and is testable. Some of the advantages are: - Easier to update to newer RBD version - Allows functionality only available in the userspace RBD library (write cache, layering, ...) - Less issue when

Hi, In most cases we use image files as virtual disks under the full-virtualization situation.On the version 4.1.2 of xen,I do the following command: ############################################################ dd if=/dev/zero of=myraw.img bs=1M seek=8K count=1 #Before the command below I install the operating system in myraw.img qemu-img-xen create -b myraw.img -f qcow2 myqcow1.img 20000M

Hi, I am running XEN 4.1 on Debian 6 and I cannot find blktapctrl process running. xend is started. I installed XEN from 4.1 source following instructions here: http://wiki.xensource.com/xenwiki/XenParavirtOps http://wiki.xensource.com/xenwiki/Xen4.0 Should there be a blktapctrl process running in this version? The problem I have encountered is that I can create a domain on a raw disk image but

The HVM I am currently trying to run is Debian sarge, which I installed into a disk image and configured using qemu. I am running on an HP Proliant ML150G6, which has Intel-VT hardware

Hi all I was reading through Xen 3 user manual and saw this tap:aio should be used instead of loopback... Then I came to do that, but I can get it working with replacing `file'' URI''s with `tap:aio''.
