I''ve tryed to use LVM in my domU, but the "vgdisplay" says: --- Volume group --- VG Name xenvg System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 47 VG Access read/write VG Status resizable MAX LV 0 Cur LV 45 /proc/misc: No entry for device-mapper found Is device-mapper driver missing from kernel?

Did you check for device-mapper in dmesg?> Is this a valid idea to use LVM within a domU?Most people use LVM in dom0. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
