视窗7错误Socket.Errno：[107]的传输端点未连接

Question

我有Ubuntu的LTS 16.04上的Windows 7的服务器计算机上托管的虚拟框运行。我运行需要两个不同的软件（OpenFOAM和PFC3D）之间耦合的耦合的模拟。这里是我的客户端和服务器的代码：

客户：

from itasca import p2pLinkClient
import numpy as np
from pyDemFoam import pyDemIcoFoam

solver = pyDemIcoFoam()

with p2pLinkClient() as pfc_link:
    pfc_link.connect("10.0.2.2")

    pfc_link.send_data(solver.nodes())
    pfc_link.send_data(solver.elements())
    pfc_link.send_data(solver.rho())
    pfc_link.send_data(solver.mu())

    while True:
        print "waiting for run time"
        deltat = pfc_link.read_data()
        if deltat == 0.0:
            print "solve finished"
            break
        print "got run time", deltat
        solver.n(pfc_link.read_data())
        solver.f(pfc_link.read_data())
        print "got runtime and data"

        solver.set_dt(deltat)
        solver.solve(deltat)

        print "sending data to pfc"
        pfc_link.send_data(solver.p()*solver.rho())
        pfc_link.send_data(solver.gradp()*solver.rho())
        pfc_link.send_data(solver.U())
        print "send finished"

服务器：

import itasca as it
from itasca import cfdarray as ca
from itasca.util import p2pLinkServer

import numpy as np

with p2pLinkServer() as cfd_link:
    cfd_link.start()

    nodes = cfd_link.read_data()
    elements = cfd_link.read_data()
    fluid_density = cfd_link.read_data()
    fluid_viscosity = cfd_link.read_data()
    print fluid_density, fluid_viscosity
    nmin, nmax = np.amin(nodes,axis=0), np.amax(nodes,axis=0)
    diag = np.linalg.norm(nmin-nmax)
    dmin, dmax = nmin -0.1*diag, nmax+0.1*diag
    print dmin, dmax

    it.command("""

    ca.create_mesh(nodes, elements)

        print "sending solve time"
        cfd_link.send_data(dt) # solve interval
        cfd_link.send_data(ca.porosity())
        cfd_link.send_data((ca.drag().T/element_volume).T/fluid_density)
        print " cfd solve started"
        ca.set_pressure(cfd_link.read_data())
        ca.set_pressure_gradient(cfd_link.read_data())
        ca.set_velocity(cfd_link.read_data())
        print " cfd solve ended"

    cfd_link.send_data(0.0) # solve interval


    print "ball z velocity", it.ball.find(1).vel_z()

我跑进错误：Socket.Errno：[107]的Trasnport终点未连接，当我开始所耦合的计算。这个问题被张贴，并解决了MAC操作系统，但没有窗户。我试过MAC解决方案，但它并没有帮助。任何人都可以请帮助呢？

在Python代码客户端，IP地址是不允许进行连接。我曾尝试相同的例子，但在主机的Ubuntu，游客窗口组合。通过VirtualBox的创建静态IP我解决了这个问题。使用在pfc_link.connect("Static Ip of VBox")上的代码客户端。
