Right, see my comments on that. I'm not sure what feature it provides, apart from something that could be done with qemku-img. > 2, vm snapshot(memory save, snapshot the whole snapshot with transaction qmp > opeartion, only support internal disk snapshot at this step. > in this step, we plan to add the vm snapshot record in xenstore in domain in > order to management the status of vm snapshot. I'm not sure what you mean by "add the vm snapshot record in xenstore". I don't know what "vm snapshot record" is exactly. If you mean the domain save state it's far too big for xenstore. > question: > in GSOC2013, there is a requirement: "Add VM snapshot functionalities to libxl > save/restore and migration functions". is it mean add a flag to create > snapshot > in save, revert snapshot in restore besides the dedicated vm snapshot command? > or just implement the snapshot in save, restore and migration? > it might be more clear for user if there is a dedicated snapshot command. I agree that a dedicated command might be clearer. This is a matter for the implementor to think about and decide in consultation with the community. I don't think the 2013 GSOC requirement was intended to specify an xl UI. > 3, some "advanced" feature such driver-mirror, support other backend. > > when i prepare to send this out, i found that there is a GSOC project during > community review this week. i am sorry about i do not send this discussion > eariler. sorry if i break the plan of xen community. We welcome contributions from anyone, whether within GSOC or without. Sadly sometimes that means things come in parallel, which can involve duplicated work. We'll know fairly soon which GSOC projects have been accepted. Ian. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
