You can try this from dom0 (in this example the domU uses LVM): kpartx -av /var/lib/xen/images/vm2.img You may need to install kpartx yourself, not sure if it comes "free inside" (yum search kpartx on CentOs) maps disk partitions to device table entries uses losetup to create loop devices to disks vgscan To find volume groups on the newly mapped disk vgchange -ay VM_VG00 Activate the volume group you need, VM_VG00 is just an example... mount /dev/VM_VG00/VM_LV00 /mnt Mount the filesystem you want, Make your changes umount /mnt vgchange -an VM_VG00 kpartx -dv /var/lib/xen/images/vm2.img To unwind things.
