I use a VirtualBox machine as a local web server (this is an Open Suse VM). But for a few days, problems occurs with my VM.

First, I can't delete my oldest snapshot, the reason is:

Result Code: NS_RROR_FAILURE (0x80004005)
Component:   SessionMachine
Interface:   IMachine {480cf695-2d8d-4256-9c7c-cce4184fa048}

Another issue came today:

VirtualBox - Guru Meditation

A critical error has occurred while running the virtual machine and machine
execution has been stopped.

[...]

Press OK if you want to power off the machine of press Ignore if you want
to leave it as for debugging. Please note that debugging requires special
knowledge and tools, so it is recommended to press OK now.

It's pretty painful, because, it's the third time it happens, and I can't work on my web server...

Here is the link to the VirtualBox log file

Note that, I just upgraded my Lubuntu from 12.10 to 14.04 (I got problems during this upgrade -- blank screen when I was booting, but I fixed them). Open Suse is running on my VM, and I use Interbase, PHP, Apache. The first time the issue happened, I was using Netbeans, then it was when I was using Kwrite. I previously got many networks problems with this VM (it's the reason why I take snapshots to avoid rebooting).

Why am I receiving critical errors when attempting to run the virtual machine?


Today I got the same error message, and resolved it by closing the Android Emulator that was also running.

I've figured the answer. 99 Percent of the cases including me will have the same solution. We have assigned more memory for the VM so the Host system does not have enough memory to handle VM. You can get rid of Guru meditation by assigning less memory to the VM. you can do this by: Open Vm>Settings>System> And reduce assigned memory to a lesser value.

Hope it helps.
