How about using the following patch with
+#if !defined (_WIN32)
.bdrv_get_allocated_file_size = nfs_get_allocated_file_size,
+#endif
Also,
+static blkcnt_t nfs_get_st_blocks(const struct nfs_stat *st)
+{
+#if defined(_WIN32)
+ return (st->st_size + 511) / 512;
+#else
+ return st->st_blocks;
+#endif
+}
Change to be
+static blkcnt_t nfs_get_st_blocks(const struct nfs_stat *st)
+{
+#if defined(_WIN32)
+ return-1; /* TODO: unimplemented on win32 yet */
+#else
+ return st->st_blocks;
+#endif
+}
