Hi, I install xen 4.1.2 on centos 6 with linux kernel 3.0.4 as dom0 kernel. When I launch virt-manager on the command line ,a window pop up which show the following error: Unable to open a connection to the Xen hypervisor/daemon.

Hi, I encounter a problem that has puzzled me for a long time.On a Xen virtualization platform, some VMs ,whose virtual disks are image files ,are running in DomUs.Under this situation ,does the Dom0 cache the pages from the VMs?Does the filesystem in Dom0 see the VMs as general processes?

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

tags 490409 + patch thanks Hi, The following is the diff for my xen-3 3.2.1-2.1 NMU. It incorporates three patches from upstream and aims to fix CVE-2008-2004 aka #490409.

Kind regards T. diff -u xen-3-3.2.1/debian/control.md5sum xen-3-3.2.1/debian/control.md5sum ---

Hello, I am setting up a new (remote) server. I initially installed 9.2 RC4 amd64 because that's what the data center put in the drive for me. Shortly thereafter I downloaded 9.2-STABLE sources and compiled world and a generic kernel. While doing so the system became unreachable by SSH The SSH sessions appeared to connect but there was never any data returned. I could telnet to port 22

Hi everyone, I thought long and hard (ok, not *that* long) about whether or not to crosspost this to icecast-dev. In the end I decided not to since this isn't about an Icecast or Xiph project. My name is Geoff Shang and I've been an enthusiastic user of Icecast for a long time. I am also the chief tech guy for a project called ACB Radio (http://www.acbradio.org), which is run by

Hi,mail list members, As needed by my test, blktap/blktap2 modules have to work after new VMs start.Maybe the line about disk in the vm creation configure file is the right position where I should be supposed to specify the function of blktap/blktap2 modules.But specifically I don''t know how to configure the disk line.Who can help me? hxk

Hi, Is there a way to tell / narrow down if an issue with errors like below are due to a bad cable or bad port multiplier ? The disks in a particular cage are throwing errors like these below.

Hi: Since I'm not a programmer and just want to get stuff worked out properly in my head, I'm posting this here. I just want to be sure I have all the concepts regarding vorbis and high sampling rates at low bit rates all sorted out. Note that this will involve questions, some of which I've been looking for answers to for some time. The way I understand things is that vorbis is

For many months now we have been trying to create a file-backed qcow image with the qcow-create code. Each time we try to back a file with a qcow, it screams: *** buffer overflow detected ***: qcow-create terminated Below is the output from two different attempts and information about qcow-create. Any ideas/thoughts/help you can offer? Thank you for your help! -Eric [root@trogdor ~]#

Hello, I've got a (P)ATA disk in a special frame. The disk itself supports UDMA-100 (and has an 80-ribbon cable), but the frame isn't compatible with that. By default, FreeBSD negotiates UDMA-100, and the console starts to fill with ICRC errors. In the past, I used a patch to ata-all.c that enabled the following entry in loader.conf to force the disk to UDMA-33, so it worked fine:

Hi, Trying to understand the current state of affairs with QCOW support in Xen with the blktap driver. It''s been made clear that a deviation from QEMU''s implementation of QCOW has occurred and that the QCOW files used in Xen must be created with the associated Xen tools only (e.g. qcow-create) and that images between QEMU and Xen are not interchangeable. My first question is

Hi, I want to ask if anyone of you is familiar with QCOW and has used this with xen? I''ve googled a bit about and could''nt really find out if it''s a good choice or not. Has anyone experience with usage in xen and can say something about performance and snapshot usability? Thanks in advance, Alex _______________________________________________ Xen-users mailing

Hello, I have a question with password never expired flag during changing password. If X flag for password never expired has been set in account flags for a user, password change would cause to lose the X flags. By taking a look at the code of the line 993 in passdb/passdb.c, it said all other acb flags will be inherited from current existing account ctrl bit, except for

Hello, This is a second post, with a trial which is different from the first one , in order to solve my blcok-attach problem. I tried the following two actions, according to the blktap readme: qcow-create 1000 qcowFile.img Creating file size 1048576000 Created cksum: 1813725440 then xm block-attach 0 tap:qcow:qcowFile.img /dev/xvda1 w 0 I see in the /var/log/xen/xend.log: [2007-03-13

Hi, i would like to use qcow2-sparse-images which point to a backup-file. After reading this: http://wiki.xensource.com/xenwiki/DmUserspace i figured out that this feature seems to be unsupported by the ubuntu 8.04 LTS kernel and xen-3.2.1. Is this a ubuntu-specific problem, or is it solved in Suse, Red Hat, XenSource, whatever? When i try to block-attach it, xm displays no error, but the
