Failed to start network name resolution

Post by yacarsan »

I obtained this error while trying to access the machine. I didn´t have any problems before but it stopped working and I need some documents that are inside the machine and I don´t know how to access it. I tried clonning the machine and the error was the same.

How were you:

Does this mean you were trying to start the VM? Or Access it over a network?

Start the VM from full power off, not save-state. Run until you see the problem happen, then shut down the VM from within the VM OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Please right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.

Also, Please right-click the VM in the main Virtualbox window's VM list, choose "Show in Explorer/Finder/File Manager". In the window that opens, zip the VM's .vbox file, and post the zip file, using the forum's Upload Attachment tab. (If you have a Windows host, please make sure all file extensions are shown, so you will be able to see the .vbox extension easier.)

RAM is overcommitted:
00:00:02.978713 Host RAM: 16303MB (15.9GB) total, 7364MB (7.1GB) available
00:00:03.143757 RamSize <integer> = 0x0000000280000000 (10 737 418 240, 10 240 MB, 10.0 GB)
Video RAM is undercommitted:
00:00:03.143933 3DEnabled <integer> = 0x0000000000000001 (1)
00:00:03.143939 VRamSize <integer> = 0x0000000001000000 (16 777 216, 16 MB)
The display is acting weird:
00:00:47.828048 Display::i_handleDisplayResize: uScreenId=0 pvVRAM=0000000000000000 w=800 h=600 bpp=0 cbLine=0x0 flags=0x2 origin=0,0
00:00:47.829889 Display::i_handleDisplayResize: uScreenId=0 pvVRAM=000000000d510000 w=800 h=600 bpp=32 cbLine=0xC80 flags=0x1 origin=0,0
00:00:47.831785 GUI: UIMachineLogic: Guest-screen count changed
(repeated ad infinitum)
Try 4GB regular RAM. Also try 128MB video RAM, or keep what you have and turn off 3D acceleration.

The VM's OS might run better if you give the VM 2 processors instead of the 1 you have now.

Network actually seems to run OK, so I doubt the "Failed to start network name resolution" is really the problem. It's more likely a "not quite ready during boot" report that normally goes away as the VM finishes booting and clears its screen, but which apparently never shows because the display is acting weird.

Looks like that's the same log as the one posted before?

This new log does not have the display issue it had before. The VM runs normally and ends normally. I don't think this is a Virtualbox problem, at least not that I recognize. It may be a problem inside the VM's OS. Try pretending the OS is installed on a real computer and troubleshoot using the OS support channels.

I don't understand this, autocorrect maybe took over?
