I got the "VirtualBox - Guru meditation" window when I tried to run my virtual machine.

Apparently the image file used by this VM is "inaccessible and is being ignored". How can I fix this?

Here is top part of the log file (I am uploading the complete file):

I think I might have solved it.

I went to the media manager and released the hard drive from the virtual machine.
Then I went to the settings for the Virtual Machine and removed the hard disk.
Added the original hard disk and I was able to start the Virtual Machine again.

No idea why this happened, but happy I got it to work.

Thanks,

Actually, the warning you quote had to do with an ISO you had probably deleted, the warning had nothing to do with the hard disk, nor did it have anything to do with the guru meditation :-

That's a low memory error. The reason is made clear in a couple of lines near the top of the log.

...
00:00:01.209470 RamSize <integer> = 0x0000000145400000 (5 456 789 504, 5 GB)

I.e. you allocated 5GB RAM on a host which only had some 4GB free. For reliability you need to allocate substantially less RAM to the VM, say around 2GB.
