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, 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, Ive just tried Xen 4.0 on Gentoo with 2.6.32 (also tried 2.6.31) forward ported dom0 kernel, Xen itself seems to boot up successfully and everything else on the system is working normally, but when I try to start a domain xm create appears to hang and eventually I get a hotplug scripts error: Error: Device 2049 (vbd) could not be connected. /etc/xen/scripts/block failed; error detected.

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. Verify that: - A Xen host kernel was booted - The Xen service has been started Details: Unable to open connection to hypervisor URI ''xen:///'': no

Hi all. I''m using sles11 for my xen servers. I would really like to be able to do hot snapshots of disk AND memory, and then have these snapshots backed up to tape or off site for disaster recovery. I''m thinking this would be done weekly or monthly, not nightly. Two questions: 1) Is this even possible? 2) I could probably have the systems shutdown to make a clean backups, but

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

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 guys, i''ve just installed xen 4.0. Since always blktapctl has never worked on my dell 1950III. I even posted a bug but so far i can''t use tap:aio or similar. I thought that with version 4 this would work, but it didn''t. I still see syslog errors from blktap version 1.0.0. Today i wanted to try version 2 I found on the xen/tools source folder. I compiled the source

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.

Hello, I just started writing a wiki page about blktap2. It''s here: http://wiki.xensource.com/xenwiki/blktap2 I need more information about blktap2.. I''m not very familiar with it myself.

Hey all, I have need to boot 32bit domu''s on a amd64 system. I was able to deploy a 32bit image but the kernel is still 64bit. I have a feeling in my .cfg file for the domU I need to specify a 32bit kernel. Is this correct? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

At long last, I've got some beta CentOS 6 4.4.1 packages up on the CBS. Major updates include: * Update to Xen 4.4.1. Also includes all XSAs through 114 * Update to latest blktap 2.5 * Updated libvirt packages (1.2.10), which work well with libxl To use, add the following to a file in /etc/yum.repos.d: [virt-testing] name=CentOS-$releasever - virt-testing

Get blktap2 running on pvops. This mainly adds eventfd support to the userland code. Based on some prior cleanup to tapdisk-queue and the server object. We had most of that in XenServer for a while, so I kept it stacked. 1. Clean up IPC and AIO init in tapdisk-server. [I think tapdisk-ipc in blktap2 is basically obsolete. Pending a later patch to remove it?] 2. Split tapdisk-queue into

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
