[Qemu-devel] [PATCH for-2.7 4/4] virtio-balloon: fix stats vq migration

The statistics virtqueue is not migrated properly because virtio-balloon does not include s->stats_vq_elem in the migration stream. After migration the statistics virtqueue hangs because the host never completes the last element (s->stats_vq_elem is NULL on the destination QEMU). Therefore the

Previously all test cases in a category, such as check-qtest-y, are executed in a single long gtester command. This patch separates each test into its own make target to allow better parallism. Signed-off-by: Fam Zheng --- This saves 50% of the time "make check takes" compared

[Qemu-devel] [Bug 1603734] Re: Hang in fsqrt

Thanks for this bug report. The problem here is that QEMU is not correctly handling the obsolete "unnormal" 80-bit floating point format. The Intel architecture reference says that this should be handled by raising the invalid-input exception and returning the default NaN. See also the discussion

[Qemu-devel] [PATCH v4 1/2] trace: Remove 'trace_events_dstate_init'

Removes the event state array used for early initialization. Since only events with the "vcpu" property need a late initialization fixup, threats their initialization specially. Assumes that the user won't touch the state of "vcpu" events between early and late initialization (e.g., through QMP).
