[Qemu-devel] [PATCH v3 1/6] vl.c: do not save the RAM state when Xen is enabled

[Stefano Stabellini <stefano.stabellini@eu.citrix.com>]

From: Anthony PERARD <anthony.perard@citrix.com>

In the Xen case, the guest RAM is not handle by QEMU, and it is saved by
Xen tools.
So, we just avoid to register the RAM save state handler.
