[sheepdog] QEMU with sheepdog reconnect support

[MORITA Kazutaka]

Hi,

Unfortunately, sheepdog reconnect patches didn't merged into qemu 1.6.
However, for users who want to test the feature ASAP, I've rebased
them onto qemu v1.6.0-rc2 and pushed to

  git://github.com/collie/qemu.git

I'll rebase and push again after the qemu 1.6 release is out.

Thanks,

Kazutaka
