vmware workstation "Could not open /dev/vmmon"

Bug Description

10.04 LTS 64-bit
VMware Workstation 7.0.1 build-227600
I expect my guest OS to load.
I get an error "Could not open /dev/vmmon..."

This issue is due to the VMware service not starting and is not consistent. It happens about 80-90% of the time after a reboot. The other 10-20% of the time the guest loads fine. I am able to resolve the issue by using the command "sudo service vmware start" in a terminal session but that only works until the system is rebooted again. This issue is new since I upgraded to Ubuntu 10.04 LTS.

The same issue here.

VMware Player: 3.1.0 build-261024
Host kernel: 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 08:03:28 UTC 2010 x86_64 GNU/Linux

If I manually start the above mentioned command 'sudo service vmware start' everything works OK until the system reboot.

This issue is just a few days old; VMPlayer worked correctly in 10.04 for months...

This issue and a couple others seem to have been resolved in a recent update. However I have not using Workstation regularly recently so I will hold off saying this has been fixed until I have fully tested it.

I am experiencing the same problem. I have the latest updates and still vmware (vmmon) is not starting at boot, requiring manual start.

The issue has returned for me too. After an update a while back it went away then an update or two later it came back but with a lesser severity. Most of the time I can launch Workstation just fine but every once in a while I still need to manually start the service. I have been using Ubuntu since 7.10 and I have to say that so far Ubuntu 10.04 LTS is the first version to disappoint me. Hopefully the next release will be less buggy.
