Hi. We are running xen-3.0-testing. We use loop back mounted file systems. The server we are running restarts itself/crashes. This seems to happen around setting up loop back devices. (>63 loop back devices seems to trigger a crash, but we have seen then with fewer devices mounted as well). We have swapped all hardware (bar the disks) to a new server. Same issue. I see no disk

Hi all When I have a domU that resides in the auto directory I get ''Error: Device 2049 (vbd) could not be connected'' and the domain starts in a paused mode. Shutting it down and restarting has the same effect. Following is some output from the xm log and an attempted restart. Directly after dom0 reboot: xen0:/etc/xen/scripts # xm list Name ID

Hi. I''ve just upgrade my xen 3.0.1 to xen unstable. I noticed that there is no vmx driver here, only hvm. Actually I cannot start my VT domain: root@akira:/etc/xen# xm create bluszcz.hvm Using config file "bluszcz.hvm". Error: Device 768 (vbd) could not be connected. Backend device not found. root@akira:/etc/xen# my config: import os, re arch = os.uname()[4] if

Hi, I have seen many posts regarding this but have not found the soultion. So please cna someone shed some light on this Thanks - padma I get this error when I do try to create a domU guest (xen 3.0.0, 2.6.12.6).

hi, I am trying to start a new domainU but got the error: Error: Device 0 (vif) could not be connected. Hotplug scripts not working I have struggled with it for a long time. I found somebody else report this but can not find a solution. The xen version is xen-3.0 latest version. I do not have a initrd. Domain0 works fine but when I create a new domain, it always gives an error as above. Thanks,

Hi, Thanks or all the suggestions. The problem was the lack of hotplug support! The problem was solved by a reinstall of the native linux (RHEL4) with selecting all packages. I had initially chosen some packages and I believe hotplug support was left off (don''t know which package it belonged to.

I''m running Xen3 7775 with udev 073 (which was a PITA to get working, as the initrd I''ve been running for quite some time uses an older one -- but that''s an entirely different story). My dom0 is Gentoo-based. When I try to start a DomU, it times out waiting for hotplug-based notification, as per the following: DEBUG (DevController:69) Waiting for devices vif. DEBUG

Hi I''m a sysadmin and I''ve installed on my server Red Hat Enterprise Linux 5 to use its xen embedded with six virtual machines just created and running. Now I have a problem: when I attempt to create my seventh virtual machine, xen gives me this error: Error: destroyDevice() takes exactly 3 arguments (2 given) In /var/log/xen/xend.log find this errors: [2007-11-13 11:34:00

After a yum update my two guests that had been shutdown do not start any more. I have two other guests running that seem to work okay but I am now afraid that they won't come up again if I restart them. I am running CentOS5 with kernel 2.6.18-8.1.8.el5xen. Previously I had following xen versions installed: Oct 14 23:45:10 Updated: xen-libs.i386 3.0.3-25.0.4.el5 Oct 14 23:46:05 Updated:

Hi, I cannot boot Windows XP domU on SXCE104 dom0. It was running for weeks.. Is it a known bug? # virsh start wxpp01 & # virsh dumpxml wxpp01 <domain type=''xen'' id=''-1''> <name>wxpp01</name> <uuid>fb96e8c9-940d-7e0a-12ef-f167a7f1102c</uuid> <os> <type>hvm</type>

Hi, I have been trying to get Xen 3.1 running on Fedora 7 since yesterday and no luck. At the beginning I thought it was a problem with teh installation of Fedora 7 so I reinstalled it. Still, I have the same problem. I have never had this problem with Xen (FC5,FC6). The xend.log (below) includes a line "VmError: Device 0 (vif) could not be connected. Hotplug scripts not working."

Hi all, I installed 2009.06, xVM and happily installed a domU with no issues. I just did this through the virt-manager GUI, and kept it as simple as possible. Later I installed and booted a zone with very simple and standard configuration. My existing xVM virtual machine did not immediately stop working, or have any interruption at all. But, I can no longer create new virtual machines, or even

Hi, I have been getting the following error (logged in /var/log/xen/xend.log) when I try to migrate a VM from one particular host to the other (the reverse migration works fine). My system was working fine for a long time (i did several migrations in both the directions). I am using Xen-3.4.3 (installed from source code) with CentOS 5.4. I am using drbd to replicate the disks.

Hi List, beneeth some debian domU''s I tried fedoraCore3 from xen-get... My tests are sucessfull bu I can''t reboot this domU.

Hi, every one: I had problem creating domU on diskless device by using xen-unstable. Following, please find out details. BTW, the same configuration works fine on device with hard disk (1) Xen, dom0 kernel and dom0 root file system are loaded/mounted over via eth0 (2) DomU root file system is created in a file-backed virtual block device(VBD). The file-backed VBD locates at some directory on

Yes, I saw that problem and removing the vif line or changing it to vif0 fixed it for me.
