[libvirt] An API to copy files.
Hi guys, Unfortunately, my company does not allow access to IRC. I need to ask question by email. Why doesn't libvirt have any method to copy files? A kind of virFileCopy(src, dst) for example. Libvirt has a lots of helper functions but it does not have a specific method to copy a file. There is a similar method inside openvz_conf.c. But I don't see any method inside virfile.c -- Julio Cesar Faracco
I think io_helper is a good tool for copy a file, it can be avoided libvirtd fail into uninterruptible sleep status when file system is unreadable or unwritable. On 2017/7/24 3:28, Julio Faracco wrote:

Do you mean a public API (1) or a helper method for internal use(2)? (1) Because copying files is not libvirt's job. (2) Because apparently nobody needed it yet.
Libvirt has a lots of helper functions but it does not have a specific method to copy a file.
Solutions: (1) Libvirt has method which allows to create a new storage volume by copying data from the old one. (2) Write such method if you need it and can justify it.
