"One or more virtual hard disks, CD/DVD or floppy media are not currently accessible."
My virtual machine becomes inaccessible. Details show this error:
Could not find an open hard disk with UUID {5bad2863-64d0-40a2-a394-7442e3a6adc7}.
Result Code: VBOX_E_OBJECT_NOT_FOUND (0x80BB0001)
This happens when a snapshot is removed, then another snapshot is made and the host computer crashes (e.g. freezes during hibernation). After this, there is a reference to a non-existing HardDisk in the configuration file "~/.VirtualBox/VirtualBox.xml". This needs to be updated with the real value. The last working situation can be found in the log file (e.g. "~/.VirtualBox/Machines/<...>/Logs/VBox.log")

This shows reliably the structure (the snapshot and its parents are listed), so it can be reconstructed by editing the XML file accordingly.

I have that exact problem. But aren't sure what to put where? an example would be great. thanks
ReplyDeleteYou can send relevant parts of your log, like above, and of your VirtualBox.xml (inside <HardDisk> tags).
ReplyDeleteWe will create an example this way :-)
how to?
ReplyDeleteI hv same problem in V1.vbox
ReplyDeletehow to?
ReplyDeleteDo you see the list of HardDisks in the file "~/.VirtualBox/VirtualBox.xml"? Some of them need to be removed.
ReplyDeleteHi,
ReplyDeleteThank you for this article; I have a question.
In your example, the UUID in the error message is the same as the UUID in the logfile (you do not show your xml file which would also be useful for better understanding I guess).
Based on the description I was expecting that in the logfile I'd find a different UUID which is the one that I'd need to add to my XML file overwriting the UUID that is shown in the error message.
Could you please let me know where to get the good UUID from?
Thank you,
Jakab
Hi Jakab,
ReplyDeletemaybe the explanation is not detailed enough.
Unfortunately, I cannot reproduce it anymore with "Oracle VM VirtualBox Manager 4.1.12_Ubuntu"... And I cannot find the "bad" XML file.
Also when I try to post XML tags here, they are invisible. That is why I could not quote it more clearly...
Anyway, I guess that the parent of the Harddisk was wrong, not the UUID that is mentioned in the error (or it was OK in the XML of the machine but not in the global VirtualBox.xml), I do not remember exactly anymore.
And do not forget that you have to look at the last working scenario in the logfile, not just the last one.
I could have a look at the XML that cause you problems.

Thanks! Helped to solve my problem.
ReplyDeletei have the feeling that virtualbox is crap and that i should use qemu -.-
