[opensuse-project] Re: "[GSoC]project : add snapshot support to libvrit xenlight driver"

Hi there, This week I managed to get most of the work on the libvirt xenlight driver done. There is some kind of problem on the xen llibxl, developers are not very sure about how exactly it should be done and me and my mentor realized it may take longer to get the work acked in libxl.I worked around that by patching xen to provide some imaginary API.This API should be what will be provided when the xen libxl work gets acked. The libvirt work is now almost complete(considering the imaginary API) and I will push it to github over the weekend( https://github.com/Aslaville/libvirt-SoC- ).The patch will have to wait for the xen libxl work to get acked so that it can be pushed to libvirt master. We then agreed with my mentor that over the coming period I will work on something else. This will be a parser for changing the xl configuration format to libvirt XML and vice versa. Regards, David.

Hi there,

Let me not start another thread because I don't have much to report.

This week I finished working on the above functions and I few other helper functions.

Next week I will hopefully take on the actual snapshot functions and finally the beast domainSnapshotCreateXML

Regards, David.

Hi there,

This week I worked on helper functions which are needed by the major functions(API) which I am supposed to implement.This included

1)libxlsnapshotMetadataWrite This function should be called each time a snapshot is taken to update libvirt xml metadata to track the snapshot.

2)libxlSnapshotMetadataUpdate This function should be called on various occasions e.g to update the current domain xml config after taking or deleting a snapshot.

3)libxlSnapshotForEachQdisk This function is a wrapper function around xen libxl's disk_snapshot function.I takes care of all the disks on a domain.This is what should be called when taking the internal snapshot of an inactive domain.

4)libxlSnapshotObjFromSnapshot This function takes a snapshot and returns a snapshot obj representation.The difference between the two being that the "snapshot obj" structure has more information.

Also because I am following the libvirt qemu driver(which I this has a lot of boiler plate code anyway) I was thinking about having functions to prepare the disks for snapshots.Here I am taking of checking the user commands for errors and maybe some operations which are not supported.

All in all, I will continue working on this and should be done next week.

*Ahem*,..sorry for writing sooo much detail.I just don't know how else to explain this.
