Read-only file system

[tansaku]

I just made a clone of a vdi in order to create a second copy. That all worked fine. I have two VMs from the original VDI. However not the original is giving me the following error:

saasbook@saasbook:~/Documents/github/LocalSupport$ git pull
error: cannot open .git/FETCH_HEAD: Read-only file system

Has anyone ever had this before. I saw some mention of it on the windows forums, but none here. I'm on OSX 10.8.4 and VirtualBox 4.2.16

I used the clone mechanism in virtual box to make a full clone of the original - and then I deleted the original to allow me to make a fresh VM from the original VDI image. I can read and write files fine on the new VM, but the cloned VM gives this read only file system error.

Any help much appreciated.
