vMotion Issue

[CollabSensei]

Running Esxi 5.5. When vmotioning a vm with a serial interface on it, the VMware Client says "An error occurred while saving the state for migration.
The serial port concentrator did not acknowledge the migration within the allowed time limit. ".

From a logging perspective from vSPC, I see the following:
05-30-2015 09:34:06 User.Error 10.255.83.94 May 30 08:34:06 ps-collab-vsc vSPC.py[1027]: Worker exception caught#012Traceback (most recent call last):#12 File "build/bdist.linux-x86_64/egg/vSPC/server.py", line 112, in _queue_run#012 queue.get()()#12 File "build/bdist.linux-x86_64/egg/vSPC/server.py", line 224, in #12 self.task_queue.put(lambda: self.new_vm_data(vt))#12 File "build/bdist.linux-x86_64/egg/vSPC/server.py", line 179, in new_vm_data#012 neg_done = vt.negotiation_done()#12 File "build/bdist.linux-x86_64/egg/vSPC/telnet.py", line 276, in negotiation_done#012 self.process_available()#12 File "build/bdist.linux-x86_64/egg/vSPC/telnet.py", line 273, in process_available#012 self.process_rawq()#12 File "build/bdist.linux-x86_64/egg/vSPC/telnet.py", line 156, in process_rawq#012 self.option_callback(self.sock, c, NOOPT)#12 File "build/bdist.linux-x86_64/egg/vSPC/telnet.py", line 415, in _option_callback#012 getattr(self, meth)(data)#12 File "build/bdist.linux-x86_64/egg/vSPC/telnet.py", line 34...

function _handle_vmotion_begin has a bug. try change to 👍

def _handle_vmotion_begin(self, data):
    cookie = data + struct.pack("l", hash(self) & 0xFFFFFFFF)
    if self.handler.handle_vmotion_begin(self, cookie):
        logging.debug("vMotion initiated: %s" % hexdump(cookie))
        self._send_vmware(VMOTION_GOAHEAD + cookie)
    else:
        logging.debug("vMotion denied: %s" % hexdump(cookie))
        self._send_vmware(VMOTION_NOTNOW + cookie)

I confirm this issue.

Running ESXi 5.5u3, I have a cluster of 2 ESXi and when I try to migrate a VM with a serial port configured for the vSPC server it fails.

This does not happen with other VM with a serial port configured on an Avocent (a commercial virtual serial port concentrator)

Error output:

A general system error occurred: Migration to host <> failed with error Connection closed by remote host, possibly due to timeout (0xbad003f).
Migration to host <> failed with error Connection closed by remote host, possibly due to timeout (195887167).
vMotion migration [-1062076156:1476173590574550] failed to send init message to the remote host <>

The vMotion failed because the destination host did not receive data from the source host on the vMotion network. Please check your vMotion network settings and physical network configuration and ensure they are correct.

I confirmed that the patch mentionned by xuguanghan is fixing the issue.
This issue is also a duplicate with issue #17. Can you fix this issue and merge it with master ?

Fixed in master.
