[Xen-devel] [PATCH for-2.4 v3 0/3] Migration regressions with Xen.

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

Hi,

We've spotted several regression which prevent migration with Xen using the
same version of QEMU or from a previous version of QEMU (tryied with 2.2).

Regression have been introduce by at least:
- df4b1024526cae3479da3492d6371fd4a7324a03
  migration: create new section to store global state
- 61964c23e5ddd5a33f15699e45ce126f879e3e33
  migration: Add configuration section

The last patch fix migration for 'xenfv' machine and for 'pc,accel=xen'
machine. 'xenpv' machine is not affected as there is no emulated device
state to save.

Change since in v2:
- replace memcpy() call by a strncpy().
- Move the skip_config_section and the like from 'xenfv' machine init to
  xen_init() which is called by accel_init_machine. (in 3rd patch)

Thanks,

Anthony PERARD (3):
  migration: Fix global state with Xen.
  migration: Add configuration section to vmstate with xen.
  migration: Fix regression for xenfv and pc,accel=xen machine.
