vmWare workstation player v15:
After suspending the VM I wanted to start it again - requesting missing file, this exists but not possible to start anyhow.
Then I cleared the suspended state - Still no luck?
What could be the problem?
enter image description here
from your screen the disk that was not found seems to be only 2KB in size ... I think it is too little like a disk, it is possible that VM was corrupted during suspend/start action?

I have followed this tutorial for developing an operating system. I am using Windows 10 as my host sytem and used wsl for compiling. But my VM fails as soon as I enable interrupts.
This is the log file of the VM that is output, but I cannot understand it. I am pretty naive with VirtualBox. Can someone explain any possible error you see?
Here is the code of the Os. I just have changed the structure I believe. Rest code in execution point of view is same as shown in video series.
That is a lot of log to scroll through and it's hard to be sure on the face of it that just looking at that would be able to tell us what about your startup code (not visible to us as part of the question) would trigger it. However, I can speak to some general strategies about approaching a log file like this.
We can see some general state transitions in there. The log ends with:
00:00:15.712045 Changing the VM state from 'DESTROYING' to 'TERMINATED'
So I can go back through and look at where the first instance of DESTROYING showed up, which was:
00:00:15.698320 Changing the VM state from 'POWERING_OFF' to 'OFF'
00:00:15.701802 Changing the VM state from 'OFF' to 'DESTROYING'
Following the same process backwards to POWERING_OFF, I see:
00:00:08.577363 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

That error line at the top of that block may point to something searchable that would turn up other instances of people having the same or a similar problem. If you scroll up a bit, you can also see that something VGA-related was happening right before the error, which may help narrow it down if it's directly related to the error, or may be another step to backtrack through on the way to the real issue.
I get the following error after upgrading via Migration Assistant my laptop from a 2-core to a 4-core processor:
cpum#1: X86_CPUID_FEATURE_ECX_MOVBE is not supported by the host but
has already exposed to the guest [ver=17 pass=final]
(VERR_SSM_LOAD_CPUID_MISMATCH).
How can i resolve the same?
The solution may be as simple as clicking the big yellow "Discard" button, which will delete the saved state (same as pulling the power cord).
Reference: https://forums.virtualbox.org/viewtopic.php?f=6&t=19351
For people working via a terminal.
The accepted answer correctly mentions to discard the current state of the VM. This basically means pull the power cord, so that the next time you start it, the machine reboots.
You can do this using
VBoxManage discardstate "your machine's name"
Click on the name of the virtual machine, right click on the menu and discard saved status
The Discard button worked for me. Thanks #Justin!
I've been chasing this exact error message off and on for months (fortunately my VM is not part of my daily work). The whole time I thought that it was an issue of being on a new CPU (based on CPUID_MISMATCH) so I was looking at how to move a VM from one CPU to another and how to change the expected CPUID. But everything I found in that searching required that you save and shut down properly on the original CPU, which I no longer have.
Simply "Discard"-ing the "Current State (changed)" version worked for me on all of my saved machines.
Whoda thunk that the fix for a virtual Windows machine was a hard reboot? Not like that works for hardware-based Windows boxes, right? ;-) I guess that's why they call rebooting "the Windows Panacea".
Thanks again.
I'm having problem making a permanent calibration in my embedded solution. I'm developing a Qt-based app for a Embedded Linux environment with touch screen. For this last part, I use tslib (configured by previous developers).
In what comes to simply calibrate the touch screen, everything is fine: ts_calibrate runs and creates the pointercal file correctly. If after calling ts_calibrate I run my Qt app (or ts_test), I can notice that the calibration is successful.
The problem is that the calibration results only works for 1 opening of my app: I calibrate with ts_calibrate, run my app, close it and if I run my app again, the screen is one again non-calibrated.
Now obviously I don't want to have to call the calibration each time my app is closed and reopened. The question is: how to make the calibration results become permanent? (that is, till another calibration is made)
Extra info:
I did some research on the web and I found this SO thread telling about a way to handle this problem using QWSServer. At first I disliked this solution since it depends on the Qt framework to do the job (I was expecting a more general, "C++ solution" (or a call to a script, whatever)). But I implemented it and it worked - but only in a specific case, namely, if I calibrate, open my software, close it and reopen it, then the calibration is maintained. But the problem nevertheless persists if I shut down the hardware completely, turn it on and run my app without a call to ts_calibrate (reloading the Linux kernel in the process); so this show to be only a partial solution and, therefore, not acceptable.
Trying to find the source of the problem, I created a copy of the pointercal file just after calibration and another copy of it after shutting down and turning up my hardware (and confirming that the calibration was over) and I noticed that the file was changed in the middle despite no call to the ts_calibrate or similar app was made:
After calibration:
55438 118 -1920736 -543 -36058 34531168 65536 800 480
After hardware shutdown:
-55040 1280 2526720 -288 35040 -34398240 -62768
The terminal log for the linux boot (tftp; bootm command) don't mention pointercal or a relevant calibration process.
Edit
I recently learned that the pointercal file located inside /etc/ is changing between sections because that entire folder is made new when the hardware is restarted. So what is essentially happening is that Tslib is going after a file that is constantly reset to default each time the hardware is restarted, and what I need to do is to configure Tslib not to look there, but to a more secure folder (in my case, the SD Card). The new question now is: how to do that? I know I have to configure the tslib.sh file making the TSLIB_CALIBFILE variable point to the new location of pointerscal, but tslib.shis itself inside /etc/, being itself temporary.
You have to change TSLIB_CALIBFILE in the image loaded via tftp.
That should do it, since you just have to change that once.

I'm trying to migrate an existing VM from VMWARE to VirtualBox. I've made a copy of the Virtual Machine folder for the VM (so I can experiment and not destroy the original) and have successfully created a VM in VirtualBox. I've got everything booting and running, but the issue is that VM is using the "flat" disk image instead of the correct disk image causing the disk image to be from the past (I know this because all the files on the machine have a timestamp of 2009).
To elaborate, in the VM's folder i have the following vmdk files:
Win2003.vmdk (1 K)
Win2003-flat.vmdk (15 gigs)
Win2003-000002.vmdk (10 gigs)
NOTE: the disk is dynamic.
Looking in the configuration of the VM under VMWARE, it says that it's using the win2003-000002.vmdk as the disk image.
When I import the disk image into VirtualBox (the Win2003.vmdk file), it uses the Win2003-flat.vmdk disk image.
My question is, what can I do to either combine or import the Win2003-000002.vmdk disk image into the Win2003-flat.vmdk disk image so that VirtualBox will use the correct disk image?
I've some instructions on using vmware-vdiskmanager.exe to accomplish this, but I get an error stating "The parent of this virtual disk could not be opened."
After many attempts I was finally able to get this working. Essentially what I did was download and use the vmware converter to merge the two disks into one. After that I was able to attach the newly created disk to VitrualBox.
The steps involved are very simple:
BEFORE YOU DO ANYTHING!
1) MAKE A BACKUP!!! Even if you follow these instruction, you could screw things up, so make a backup. Just shutdown the VM and then make a copy of the directory where VM resides.
2) Uninstall VMware Tools from the VM that you are going to convert. If for some reason you forget this step, you can still uninstall it after getting everything running under VirtualBox by following these steps. Do yourself the favor and just do it now.
NOW THE FUN PART!!!
1) Download and install the VMware Converter. I used 5.0.1 build-875114, just use the latest.
2) Download and install VirtualBox
3) Fire up VMWare convertor:
4) Click on Convert machine
6) Browse to the .vmx for your VM and click Next.
7) Give the new VM a name and select the location where you want to put it. Click Next
8) Click Next on the Options screen. You shouldn't have to change anything here.
9) Click Finish on the Summary screen to begin the conversion.
10) The conversion should start. This will take a LOOONG time so be patient.
11) Hopefully all went well, if it did, you should see that the conversion is completed:
12) Now open up VirtualBox and click New.
13) Give your VM a name and select what Type and Version it is. Click Next.
14) Select the size of the memory you want to give it. Click Next.
15) For the Hard Drive, click Use and existing hard drive file and select the newly converted .vmdk file.
16) Now Click Settings and select the Storage menu. The issue is that by default VirtualBox will add the drive as an IDE. This won't work and we need as we need to put it on a SCSI controller.
17) Select the IDE controller and the Remove Controller button.
18) Now click the Add Controller button and select Add SCSI Controller
19) Click the Add Hard Disk button.
20) Click Choose existing disk
21) Select your .vmdk file. Click OK
22) Select the System menu.
23) Click Enable IO APIC. Then click OK
24) Congrats!!! Your VM is now confgiured! Click Start to startup the VM!
I will suggest something totally different, we used it at work for many years ago on real computers and it worked perfect.
Boot both old and new machine on linux rescue Cd.
read the disk from one, and write it down to the other one, block by block, effectively copying the dist over the network.
You have to play around a little bit with the command line, but it worked so well that both machine complained about IP-conflict when they both booted :-) :-)
cat /dev/sda | ssh user#othermachine cat - > /dev/sda
QEMU has a fantastic utility called qmeu-img that will translate between all manner of disk image formats. An article on this process is at http://thedarkmaster.wordpress.com/2007/03/12/vmware-virtual-machine-to-virtual-box-conversion-how-to/
I recall in my head that I used qemu-img to roll multiple VMDKs into one, but I don't have that computer with me to retest the process. Even if I'm wrong, the article above includes a section that describes how to convert them with your VMWare tools.
Note: I am not sure this will be of any help to you, but you never know.
I found this link:http://www.ubuntugeek.com/howto-convert-vmware-image-to-virtualbox-image.html
ENJOY :-)
This error occurs because VMware has a bug that uses the absolute path of the disk file in certain situations.
If you look at the top of that small *.vmdk file you'll likely see an incorrect absolute path to the original VMDK file that needs to be corrected.
Sometimes a network drive that is already mapped to a drive letter because "disconnected". Using the normal Windows functions to access files / folders on that drive fail. As soon as the user manually clicks on that drive it the Windows Explorer dialog, it's magically repaired.
Since my program is a batch program I'd like to start this "magic" from my program (C++) but I haven't found a Windows function for that. There's nothing in the usual WNet... functions...
NET USE V: /DELETE
NET USE V: "\\server1\videos"
NET USE L: /DELETE
NET USE L: "\\server2\archive"
When the path is inserted, you could check to see if it is a network resource and before opening files, use WNetGetConnection() to get the network resource.
You could also try to use WNetRestoreConnectionW(), which seems to have more spurious support, depending on the environment.
Try re-connecting to the share via net use:
net use \\server\folder [/user:[domain\]username] [password]
If that doesn't work, you can net use /delete it first, then re-connect.
Isn't this what WNetAddConnection and WNetAddConnection2 are for?
I suspect that is really the same thing, though. Explorer probably caches the connection info somewhere in the registry. When the user tries to go to that drive Explorer sees that the mapping is disconnected, reads the connection info from the registry, and re-creates the connection. Maybe you could try running regmon while you create a drive mapping and see if you can figure out where and how the connection information is cached.
I had trouble with this at a client of mine not long ago. I don't know if it's possible in your situation, but our fix was to tweak the Server's network settings to stop the timeouts and disconnects. See MSKB 297684 for details.
I agree with the comment from CMB, above. I've been down this path (excuse the pun) in the past and it caused me no end of trouble.
If the path is user configurable, they could use m:\pathonserver or they could use \server\c\pathonserver.
It shouldn't make any difference to your code, opening a file as m:\blahdeblah.dat or \server\c\blahdeblah.dat will be identical.
Using the UNC path is far more reliable, Windows will reconnect to that path automatically whether or not the mapped letter is there.
If you map a drive to a network
share, the mapped drive may be disconnected after a regular interval
of inactivity, and Windows Explorer may display a red "X" on the icon
of the mapped drive. However, if you try to access or browse the
mapped drive, it reconnects quickly.
To avoid this behavior use the following command:
net config server /autodisconnect:-1
