...this before - it seems like this code didn't exist in the versions of qemu that were in Fedora, or somehow this code only runs some of the time. But anyway, this breaks the tests in Fedora 11 and RHEL 5.3 right now. The attached code attempts to work around this stupidity by adding checks in list_devices and list_partitions to see if the device is openable, and ignoring any which aren't. These fake, empty CD drives fail this extra check with error "No medium found", so they get ignored. [I'm still running all the tests with this patch, so not quite sure if it's correct.] Ri...

Before I rush to change something I request your comments on the subject. Let me know what do you think and if it does make sense. The issue: guesfs_list_filesystems is inconsistent in its output. For, example, it filters out partitioned physical devices but doesn't do the same for MD devices. More over, according to its name and API documentation guestfs_list_filesystem should return

Although the commit message ties this to https://bugzilla.redhat.com/1804207, in fact I believe this commit could be applied independently. It's a simple optimization. Rich.

The following patch attempts to implement sparsification of LUKS-encrypted partitions. It uses lsblk to pair the underlying LUKS block device with its mapped name. Also, --allow-discards was added by default to luks_open(). There are several potential issues that I can think of: 1) If and entire device is encrypted (not just one of more partitions), the lsblk trick might not work. 2) The
