[open-vm-tools-devel] Getting "Failed opening default VMCI device with error 2"

[Cam M. <ca...@cs...>]

Hi,

Rather sporadically I am getting an error from VMCI.  It was working 
previously.

cam@hardy:~/VMCI$ ./sharedMemApp -s
Failed opening default VMCI device with error 2.
Failed to init VMCI library.

/dev/vmci exists but strace shows the following error:
open("/dev/vmci", O_RDWR|O_LARGEFILE)   = -1 ENODEV (No such device)

Here is the output from dmesg referring to VMCI.

[713259.760719] VMCI: Major device number is: 253
[713259.762032] Probing for vmci/PCI.

[713277.483196] Opening vmci device
[713277.483568] Received open on uninitialized vmci device.

It seems the probe is failing.  I am running Ubuntu with 2.6.24-16.  Is 
it known what combination open-vm-tools version and kernel that work 
well together?

Thanks,
Cam
