Hi,

  We can seperate the xen checkpoint file as three parts: xl config file, memory dump file of the virtual machine and qemu state file.

  So I add two xl sub-commands: `xl save2` and `xl restore2`, the final effect is as follows:

[malei@xentest-4-1 Fri Dec 28 ~/honeypot/xen/xen-4.1.2]$ sudo xl save2

Usage: xl [-v] save2 [options] <Domain> <CheckpointFile1> <CheckpointFile2> <CheckpointFile3> [<ConfigFile>]

Save a domain state as three seperated files to restore later.

Options:

-h ÂPrint this help.

-c ÂLeave domain running after creating the snapshot.

[malei@xentest-4-1 Fri Dec 28 ~/honeypot/xen/xen-4.1.2]$ sudo xl restore2

Usage: xl [-v] restore2 [options] [<ConfigFile>] <CheckpointFile1> <CheckpointFile2> <CheckpointFile3>

Restore a domain from a saved state.

Options:

-h ÂPrint this help.

-p ÂDo not unpause domain after restoring it.

-e ÂDo not wait in the background for the death of the domain.

-d ÂEnable debug messages.

Besides, the `vncdisplay` option in xl config file will determine the ID of the domainU shown in `xl list`, so it's convenient to judge th vm-id according the xl config file.Â

How to submit a patch to the xen source trunk except through hg mecurial?

Does anybody ever go through such thing by sending the patch to the mail list?
