1, 5 Jan 20 12:24 zero Version-Release number of selected component (if applicable): libguestfs 1.0.80 on RHEL 6. How reproducible: Always. Steps to Reproduce: 1. export LIBGUESTFS_DEBUG=1 2. Run any libguestfs program, eg. guestfish. Actual results: Doesn't see any disks. Expected results: Should see disks. Additional info: Requires an additional kernel module to be added to the kernel module whitelist. At a guess the missing module is crc-t10dif.ko
