Probably you have 5 physical disks *partitions* *mounted* on a storage *pool* *directory* defaulting to /var/lib/libvirt/images, right? What I have found is for whatever reason, I need to put a new disk or disk-controller card into the host machine. It can changes the order of the disks as seen by the host. So vm's may not start as the physical disk they are on eg: /dev/sdd is now /dev/sdf or or /dev/sdc What can I do to protect myself from this in the future. Mount points are the mount points, regardless of the disks layout. :) poma -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

If the stated disk in Virt-Manager is sdf for eg Fedora-17 and the host then changes it to sdg, it's still sdf in virt-Manager. Thus it complains about the image not being found. -- Regards, Frank http//www.frankly3d.com -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Frank, it would be nice of you to use the correct terminology[1]. ;) Your so called virt-images are not a virtual machines per se. It is possible that you do not use physical discs as a block based storage pool, nor as a storage volumes at all - but you're adding them directly to guests as a physical devices. So an UUID[2] is probably what you need: /etc/libvirt/qemu/Magrathea.xml […] disk type='block' device='disk' driver name='qemu' type='raw'/ source dev='/dev/disk/by-uuid/x8-x4-x4-x4-x12'/ target dev='sda' bus='scsi'/ address type='drive' controller='0' bus='0' target='0' unit='0'/ /disk […] poma [1] https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/Virtualization_Administration_Guide/index.html [2] http://en.wikipedia.org/wiki/Universally_unique_identifier -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
