similar to: Device /dev/mapper/vg00-virt--linuxtest_32--0 is mounted in a guest domain, and so cannot be mounted now.

Hi, I am doing some experimentation with xen and Ceph and have a problem booting my guest when my disk = [] uses an alternate block script. Installation from a .iso was ok since the boot device was a file but now trying to boot from the rbd neither the hvmbuilder or pygrub can start as they treat the first value after target= as the /dev node to try and use. My disk parameter looks like: disk =

I created a 1TB RAID1. So far it is just for testing, no important data on there. After a reboot, I tried to mount it again # mount /dev/mapper/vg00-btrfsvol0_0 /mnt/btrfs0 mount: wrong fs type, bad option, bad superblock on /dev/mapper/vg00-btrfsvol0_0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or

I have searched the list, and don't see this covered or didn't search for the right words. I'm running CentOS 4.8 and have some DVD's for 5.4. I have a lot of customized and additional software installed and would like to avoid starting over with a scratch install. After the upgrade from the DVD I would do a yum upgrade to 5.5. Is this a workable (and safe) thing to do? What

Hi, I have a system running CentOS4.8. Last month I installed the latest updates including kernel 2.6.9-89.0.23 and rebooted the system. It has been running for almost a month. Last night I updated the system again which updated only a few packages: openssl, tzdata, curl,vixie-cron and logrotate. No new kernel or anything out of ordinary. The reboot after the update stopped with kernel

First let me say that I'm not a sysadmin, but am simply wearing that hat this week so please excuse my ignorance. I need to temporarily move some virtual servers from a CentOS-KVM platform to a CentOS-XEN platform while I do some upgrades to the CentOS box. I've created a local LV, and used DD and SCP to transfer the block device from the VKM machine to the XEN machine. For quite a

Hello , everyone I am a newcomer to xen , which i study in recent months . I have deploy the xen-4.1.2 on dell server , centos as dom0 , now , i use the vhd format to be the virtual hard disk , after i execute " xm new ***.cfg" , this vm generate the vm in "xm list" , but when i execute " xm start *** ", "Error: Boot loader didn''t return any data

I have a self built system using an Intel D 920 processor and a MB that supports VT. I''m able to run HVM domains fine, but have trouble getting multiple VCPUs for these domains. Here is an example of one of my configs. # -*- mode: python; -*- #============================================================================ # Python configuration setup for ''xm create''. #

hello all, it''s my first time ever with xen (or even virtualization in general). I installed Xen 3.2 on top of a Debian Lenny kernel 2.6.26-2-686 via apt-get. Boot options are: title Xen 3.2-1-i386 / Debian GNU/Linux, kernel 2.6.26-2-xen-686 root (hd0,0) kernel /xen-3.2-1-i386.gz dom0_mem=512000 module /vmlinuz-2.6.26-2-xen-686 root=/dev/mapper/athena-root ro console=tty0 module

I am trying to install CentOS from an ISO image file but the installer does not see a CD-ROM drive. The VNC viewer works but the CentOS installer indicates "Unable to find any devices of the type needed for this installation type." Then it prompts with "[Select driver] [Use a driver disk] [Back]". I have tried several variations of the "disk" paramater, all

Hi List, I run XEN 2 since some month (unfortunatly installed by a fiend of mine). Recently I bought some new hardware and tried to get XEN 3 running on a Debian Sarge 3.1. I installed via the Debian installer a RAID 1 with LVM. even though there are some devfs_mk_dir errors systems comes up. Now I installed XEN but system doe not boot as the boot device seems not to be recocnized by the

I installed CentOS on my home-server with 2 IDE 160GB MAXTOR HDD / RAID-1, LVM and ext3 partitions. Previous OS on this machine was FC2. I often "play" with LVM and, sometimes, have to extand or reduce some volumes size. I was surprised to see that resize2fs isn''t included anymore ! The replacing tool is ext2online but this one seems to only be able to grow a filesystem (not

This is happening on anything other than plain vanilla Dell servers. One R730, with dual Tesla cards, one R420, with a fibre card for a RAID device, it never switches root. All these systems have Xeons, not AMD CPUs. We've had this with every one of the 327 kernels. In addition, it seems to happen also with the 229.20.1; the 229.14.1 has no such problem. >From the rdsosreport: starting

I am running a Debian Squeeze Xen 4.0.1 Hypervisor and 2.6.32-5-xen-amd64 dom0. My xen-tools.conf: lvm = vg00 size = 100Gb # Disk image size. memory = 2048Mb # Memory size swap = 2G # Swap size # noswap = 1 # Don''t use swap at all for the new system. fs = ext4 # use the EXT3 filesystem for the disk image. dist = `xt-guess-suite-and-mirror --suite` # Default

In my system I''d like to be able to share one disk among multiple xen quests and boot them up using this shared disk. Is it possible to set a flag somewhere to avoid the following error. # xm create guest2 kernel="/TMP/vmlinuz" ramdisk=/TMP/initrd.img bootloader="" extra=rescue Using config file "./guest2". Error: The uname "/dev/sdz" is already

Hi... I have had a problem when I am going to detach one specific LVM partitions of Xen, so I have been trying xm destroy <domain>, lvchange -an <lvm_partition>, lvremove -f.... So I haven''t had sucess. I restarted the server with init 1 yet and nothing... I have seem two specific process started xenwatch and xenbus, but I am not sure if this processes have some action over

What are methods to debug domU when it hangs? Using xen 3.1 compiled from sources I could not manage to launch no domU. Fot instance, I run something like this: =====8<===================== disk = [ ''file:/oradata-act/sles.disk,hda1,w'', '',hdc:cdrom,r'' ] kernel = "/boot/vmlinuz-2.6.18-xen" ramdisk = "/boot/initrd-2.6.18-xen" cpus =

I''m creating a new domU using ''virsh create <xmlfile>'' without specifying the MAC address within the XML file, under the assumption that the dom0 or hypervisor generates the MAC address for me. Next I''d like to get the MAC address that was assigned to this new domU, and I don''t see a way to get that information from the command line via virsh

Package: xen-utils-4.0 Version: 4.0.1-2 Severity: normal This issue is similar to http://lists.alioth.debian.org/pipermail/pkg-xen-devel/2011-March/003217.html but since I was not able to find a bug report I'm reporting this now. Steps to reproduce: 1) cat << EOF > config name = 'squeeze64' vcpus = '4' memory = '512' disk = [
