virtualbox.org

I have installed Kubuntu 9.10 on Virtualbox with Windows 7 as host. It worked ok until I tried to access my files on Windows..... I am a newbie to Linux and Virtualbox I used the command:

mount -t vboxsrv NAME of folder /home

Then I got an error message saying that only root could do this. Then I wrote the same only with sudo in front of it (I had seen this in an YouTube video) and entered my password. After this youtube looked very strange..... I tried to log out and marked "restore snapshot". When I tried to log on to Virtualbox again, I got an error message saying that there was a critical error

I have tried to make a new Kubuntu guest, uninstalled and deleted Virtualbox, the ISO files and starting all over, but I get the same error when I have finished the installation and try to log on....

Can someone please help me? I really want to try out Kubuntu Thanks.

See section 4.7. Folder sharing of the VirtualBox Users manual. If share name is share and you created a mount point of /mnt/myshare it would actually look like this:

Thanks for your reply. I know the command was wrong. My problem is that I don't know how to make Kubuntu work on Virtualbox again.... And I really want it to get it up running again asap.....

It may be easier to just install it again. Trouble shooting an OS can be daunting to a novice.

I have already tried that (see my first post) and I get the same error message:

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

For help please see the community section on virtualbox.org or your support contract. Please provide the contents of the log file vbox.log and the image file vbox.png which you can find in the c:\users...... directory, as well as a description of what you were doing when this error happend. Note that you can also access the above files by selecting show log from the machine menu of the main virtualbox window.

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

Unfortunately I don't know how to show you the contents of the files mentioned.....

Open the main virtualbox program and click on machine. Then click on show log.
Click on save and post as an attachment here.

Here is the log file.

It comes through as corrupt. Just the file please, no compression necessary.

Sorry, but the file was too big So I had to compress it.

Well then you need to use something else to compress the file. I have nothing that will open it.

What about this one?

Try setting the RAM at either 1024 or 2048. If this does not help then post a ticket on bugtracker and attach the (complete log). Link is below my post.

Seems to be working now Thank you so much for all your help !!

Actually this Guru mediation was a long outstanding bug, see here. It will be fixed in the upcoming 3.2.6 release.
