Please take a look. This feature is necessary for in-place image expanding.

This action moves second(backup) GPT header to the end of the disk. It is usable in in-place image expanding, since free space after second GPT header is unusable. To use additional space, we have to move second header. This is what sgdisk -e does. However, sgdisk -e may perform additional actions if the partition table has unexpected params (e.g. if we call sgdisk -e /dev/sda1, it may fix

I'm pleased to announce libguestfs 1.34, a library and set of tools for accessing and modifying virtual machine disk images. This release took about 8 months of work by many contributors. Amongst the new features are large performance improvements, substantial enhancements to virt-p2v & virt-v2v, better SELinux support, and APIs for doing forensic analysis of disk images. See the release

Just to remind: I am waiting for reaction on this issue. I will create a patch for part_get/set_disk_guid, if you agree this feature is useful. Thanks!

Tried to make it in accordance with your comments. Difference to v1: Added reply_with_error where necessary. Changed name get_min_size -> vfs_min_size. Difference to v2: Changed name to vfs_minimum_size. Changed parsing to xstrtol + STR* macros where possible. Difference to v3: Decapitalize error messages.

Hello everyone! I have to implement the functionality of mounting all VM disks/partitions. E.g. if a VM has 2 disks of 2 partitions each (I get it from virt-filesystems), I want to get the following structure on host node after mount: mnt/ ------hdd0/ -------------volume1/ -------------volume2/ ------hdd1/ -------------volume1/ -------------volume2/ I'd like to use guestmount due to
