2013-07-25Revert "ioport: remove LITTLE_ENDIAN mark for portio"Paolo Bonzini
This reverts commit c3cb8e77804313e1be99b5f28a34a346736707a5. The scenario where I/O ports are accessed with DEVICE_LITTLE_ENDIAN endianness now works and will soon be unit tested. Since the PortioList indirection assumes little endian, define portio_ops the same way.

2013-07-23Fix real mode guest segments dpl value in savevmOrit Wasserman
Older KVM version put invalid value in the segments registers dpl field for real mode guests (0x3). This breaks migration from those hosts to hosts with unrestricted guest support. We detect it by checking CS dpl value for real mode guest and fix the dpl values of all the segment registers.

2013-07-23Fix real mode guest migrationOrit Wasserman
Older KVM versions save CS dpl value to an invalid value for real mode guests (0x3). This patch detect this situation when loading CPU state and set all the segments dpl to zero. This will allow migration from older KVM on host without unrestricted guest to hosts with restricted guest support. For example migration from a Penryn host (with kernel 2.6.32) to a Westmere host (for real mode guest) will fail with "kvm: unhandled exit 80000021".

2013-07-23rdma: introduce MIG_STATE_NONE and change MIG_STATE_SETUP state transitionMichael R. Hines
As described in the previous patch, until now, the MIG_STATE_SETUP state was not really a 'formal' state. It has been used as a 'zero' state (what we're calling 'NONE' here) and QEMU has been unconditionally transitioning into this state when the QMP migration command was called. Instead we want to introduce MIG_STATE_NONE, which is our starting state in the state machine, and then immediately transition into the MIG_STATE_SETUP state when the QMP migrate command is issued. In order to do this, we must delay the transition into MIG_STATE_ACTIVE until later in the migration_thread(). This is done to be able to timestamp the amount of time spent in the SETUP state for proper accounting to the user during an RDMA migration. Furthermore, the management software, until now, has never been aware of the existence of the SETUP state whatsoever. This must change, because, timing of this state implies that the state actually exists. These two patches cannot be separated because the 'query_migrate' QMP switch statement needs to know how to handle this new state transition.

2013-07-23rdma: allow state transitions between other states besides ACTIVEMichael R. Hines
This patch is in preparation for the next ones: Until now the MIG_STATE_SETUP state was not really a 'formal' state. It has been used as a 'zero' state and QEMU has been unconditionally transitioning into this state when the QMP migrate command was called. In preparation for timing this state, we have to make this state a a 'real' state which actually gets transitioned from later in the migration_thread() from SETUP => ACTIVE, rather than just automatically dropping into this state at the beginninig of the migration. This means that the state transition function (migration_finish_set_state()) needs to be capable of transitioning from valid states _other_ than just MIG_STATE_ACTIVE. The function is in fact already capable of doing that, but was not allowing the old state to be a parameter specified as an input. This patch fixes that and only makes the transition if the current state matches the old state that the caller intended to transition from.
