@SpoonyLove @olivierlambert For usb passthrough we are using USB redirector over network For anything storage related we use something like this: mkdir /adm/passSR passUUID=`xe sr-create name-label="Direct access SR" name-description="Direct acces to hdd with simlink" type=udev content-type=disk device-config:location=/adm/passSR` ln -s /dev/sdb /adm/passSR/sdb xe sr-scan uuid=$passUUID xe vdi-list sr-uuid=$passUUID Remember to replace /dev/sdb with your device.
