I am running VMware Workstation 6.1.5 (build-126130) on CentOS 5.3 (Final).
One of the guest machines was reporting an error when I tried to power on the most recent snapshot. Snapshots further back in the timeline powered on without any problem.
Error: Unable to change virtual machine power state: Cannot find a valid peer process to connect to.
Apparently I’m not the only one with this problem. Others have been reporting it since at least early 2005. The forums say to delete unused lock files and restart any hung VMware processes (or restart the host machine), which did not help.
Then I tried to clone the snapshot before making any more changes – just to have a backup – and that failed too!
Cloning failed: reached the host's limit for open files
Thinking the two errors are related, I looked into how many files are actually part of this VM. The list was HUGE. (more than 1500 files in the folder)
I had 13 snapshots before the one giving me trouble, so I deleted a few of them to reduce the number of files VMWare would need to open.
This fixed everything.
I could have increased the max number of allowable files, but some of the snapshots were not needed any longer. Your situation might be different, but this is a solution I couldn’t find anywhere else on the web. Hope that helps someone.
This is an ‘out-of-band’ post for my Accelerating Future series… I didn’t plan on covering Virtual Reality as a significant technology for change, but the folks over at Blue Mars really surprised me with this demo:
Taken in today’s context, it might look like “just another game” or “just a nice demo” but the potential is much bigger than that.
Mobile smart phones are bringing the Internet closer to everyday activities. GPS and RFID are bringing location awareness to everyday objects. Smaller (and cheaper) high definition sensors and displays are making our window into the digital world easier to wear and carry. New computer human interfaces are making our interactions with software more natural. Moore’s law is bringing the raw processing power and storage needed for life-like simulations. It’s all quite a convergence!
So virtual and augmented reality are not going to be “just a game”. They will work with all of tomorrow’s technologies to provide an environment for modeling the real world along with all its social interactions and information. Just about every part of our lives will be affected by this next step of the web, just like we have been changed by the web as it is today.
It’s been a while since I’ve posted part 2, but the Accelerating Future series is not going to be abandoned. It will probably span across most of 2009 since the rest of this year will be very busy for me. Here’s what I have planned:
Part 1: Computing and Moore’s Law – complete Part 2: BioTech – complete
Part 3: Robotics and Robots with Guns – in the works
Part 4: Nanotechnology
Part 5: Energy
Part 6: The Big Risks
