Hello everyone, I''m getting my feet wet with Xen 3.0.1 and I''m having trouble creating a DomU which uses an LVM lv as the vbd. I''ve had no problems spinning up DomU''s based on file images and on actual partitions. I''m hoping I''m just missing something simple. I''m running XEN 3.0.1 -- Debian Stable/backports Error message for ''xm create -c ./centOS-4.2_vm1.cfg Using config file "centOS-4.2_vm1.cfg". Error: Device 2049 (vbd) could not be connected. Device /dev/VG1/vmvol1 is mounted in a guest domain, and so cannot be mounted now.

Remember that the kernel and xen-tools that shipped on the released version are buggy. I''m running SuSE10 as dom0 and have succesfully run debian sarge, fedora fc4, SuSE10 and SLES9 as domU, both with file and LVM backends. rgrds, Braulio Gergull _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

The following script will list all block devices in use by xen virtual machines: #!/bin/sh # lsvbds - list all block devices in use by xen virtual machines TREE=/local/domain/0/backend/vbd for VM in `xenstore-list $TREE` ; do echo "VM `xenstore-read /local/domain/$VM/name` is using:" for VBD in `xenstore-list $TREE/$VM` ; do echo " device `xenstore-read $TREE/$VM/$VBD/params`" done done exit 0 -- Patrick Wolfe email: pwolfe@employease.com office: 404-325-7724 mobile: 404-213-1453 Yahoo!: xen2007 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
