[Xen-devel] [PATCH][RFC] xm dump-core command add on (TAKE 4)

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi,

These patches add xm dump-core command.
Commets are welcome.

Usage:
    xm dump-core [-L|--live][-C| --crash] <domID> [output path]

    -L| --live Live dump:
        By default, xm dump does an xm pause, unpause before and
        after taking the dump, respectively.  This option disables
        the pause/unpause and simply takes the dump.

    -C :| --crash crash dump: 
        This executes an xm destroy after the dump file is complete.

These patches are;
- check_status_xc_dumpcore.patch
  This patch is a bugfix patch.
  It check status of copy_from_domain_page() in 
  xc_domain_dumpcore_via_callback(). and if it failed,
  xc_core make incomplete list. 
  (I reflect commets of John)
  
- xmdump.v5.patch
  This patch adds xm dump-core command. usage is the above.
  (separate the above patch and up port to xen-unstable.hg-11389)
  
- rename_dumpcore.v2.patch
  This patch adds localtime to corename.
  And if xc_core failed, add "-incomplete" to corename.
  This patch depends on xmdump.v5.patch.
  (not change, only up port to xen-unstable.hg-11389)
