Subject: [Qemu-devel] [PATCH RFC 0/3] Migration regressions with Xen.
Date: Tue, 28 Jul 2015 16:54:42 +0100	[thread overview]
Message-ID: <1438098885-4339-1-git-send-email-anthony.perard@citrix.com> (raw)

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 first patch would fix the default case when we use the machine 'xenfv'.

But we can also use the machine 'pc' and I don't know how to fix this case.
The second and third patches are a step in the direction of fixing
migration with the machine 'pc'.

I have not look at save/restore for PV guest yet.

Thanks,

Anthony PERARD (3):
  migration: Fix regretion for xenfv machine.
  migration: Fix global state with Xen.
  migration: Add configuration section to vmstate with xen.
