Hello, is CoreOS supported by libguestfs? I was trying to run several commands some were successful others ended up with an error: for example virt-df was OK but when I tried to do virt-resize I got the following error message: root@ny2proxd03:/var/lib/vz/images/100# virt-resize --expand /dev/sda3 vm-100-disk-1.qcow2 vm-100-disk-1.qcow2.resized Examining vm-100-disk-1.qcow2 ... 100%

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
