similar to: [PATCHv2 0/3] Get/set disk GPT GUID API and support in virt-resize.

Some OSes (e.g. Windows Server 2012 R2) fail to boot if the disk GPT GUID has changed. To preserve disk GUID e.g. during virt-resize, we need a way to get/set disk GUIDs. --- daemon/parted.c | 60 ++++++++++++++++++++++++++++++++++++++++++++++++++++ generator/actions.ml | 37 ++++++++++++++++++++++++++++++++ src/MAX_PROC_NR | 2 +- 3 files changed, 98 insertions(+), 1 deletion(-) diff

virt-resize didn't preserve the per-partition GPT GUID. Now that guests using UEFI are becoming common (basically it's the default on aarch64) we need to take into account that sometimes the partition GUID is used by the bootloader NVRAM variables to identify the boot partition, so it must be preserved across resize. This bug caused the 'virt-builder --size' option to fail on

Hi, There has been discussion about the OpenStack output and Richard asked for a public thread on this list, so here it is. For v2v from VMware to RHV, there is a Python script that does some extra steps to create the virtual machine after the disks have been converted. We want to have the same behavior for OpenStack, i.e. have virt-v2v create the instance once the volumes have been created.

Hi, this patch serie adds a new GUID type in the generator, which would do the same as String, but also validating (just in the C output) the passed GUID string. This allows to reject invalid GUIDs before passing them to low-level tools. Pino Toscano (4): utils: add a function to validate a GUID string generator: add a GUID parameter type generator: generate code for parameter validation

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

Hi all, Here is the series fixing the bug I mentioned on IRC regarding the GPT attribute flags to copy to the new disk in a virt-resize.

This is a follow-up to the other generator changes in: https://www.redhat.com/archives/libguestfs/2017-February/msg00217.html Rich.

Hi all, Here is v3 of the series, taking Richard's comments in account.
