Apparently you are not using LVM inside the guest. I would do so for flexibility. If you want to resize the guest partitions from the host, you can make your guest's "hard drive" available in the host by using kpartx. You can then manipulate this device to resize the partitions on it. 'kpartx -av /dev/VolGroupV00/vm' will create /dev/mapper/VolGroupV00-vm. Resize it as you would any disk (see parted, resize2fs) then remove the device mapping with 'kpartx -dv /dev/VolGroupV00/vm' when done. See http://fedoraproject.org/wiki/Getting_started_with_virtualization#Accessing_data_on_guest_disk_images And I have some tangentially related but not directly applicable notes at http://tofu.org/drupal/node/55 http://tofu.org/drupal/node/60 Hopefully that was at least marginally helpful. -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
