Hi I have already fulfill a an issue, but it looks like it's not the recommended process. We are using a LUKS partition containing a GPT table and several partions. With libguestfs we can open the LUKS partition and the |/dev/mapper/<mapname>| device become available, but nested partition are not seen by the kernel. |partprobe| need to be run (or may be kpartx) to make partitions available in |/dev/mapper|. AFAIK there are no simple solution. As a workaround we use |guestfs_debug| but it's not a long term solution. We can see two solutions: * adding a udev rule that will automatically run partpobe when a new device appeared in /dev/mapper * adding a new API in libguestfs |guestfs_partprobe(device)| that can be call by the user when needed. What is the best best solution from your point of view? We can help implementing it.
