I am trying these instructions in linux mint 12.
It only brought me to virtualbox 4.1.6.
I’m downloading the 4.1.12 deb version for Ubuntu 12.04 (“Precise Pangolin”) x64 now and will try installing that way.
There is a horrid bug that seems to affect all VirtualBox versions 4.0.0 and after to do with shared folders which prevents the use of Truecrypt volumes on a shared folder (it corrupts them). This seems to manifest itself on Windows, OS/X and Linux although seems worst under Linux (later kernels – e.g. Ubuntu or Fedora). If I use a network mount (e.g. NFS or SAMBA) then it works fine. VMware Player does NOT corrupt Truecrypt volumes in a shared folder although it is slower (on the same hardware) and the OS/X version (VMware Fusion) is payware only.
Has anyone else noticed this problem?
It would be nice to use this facility as:
1) Truecrypt is cross-platform – i.e. I can use volumnes on Linux, Windows and OS/X
2) I can have protected data (e.g. customer data) on a machine without having to necessarily encrypt the host file system (just the child Linux VM using LUKS and external data using Truecrypt)
3) I can move VMs and Truecrypt volumes between host machines (even if they are different host operating systems) without having to change anything.
Anyone else having problems with VirtualBox and Truecrypt?
I run VirtualBOX 4.1.16 under Windows 7 and then tried to Boot “ubuntu-12.04-desktop-i386.iso” LiveCD, it shows a message telling my machine needs PAE… and do not boot Ubuntu LiveCD.
The literal message is:
This kernel requieres the following features not present on the CPU:
Unable to boot – please use a kernel appropiate for your CPU.
If i use ubuntu-11.10-desktop-i386.iso LiveCD it boots perfectly.
If i did not remember bad when i was using VirtualBOX 4.1.12 it boots “ubuntu-12.04-desktop-i386.iso” LiveCD without any problem, as i say if i did not remember bad.
Hope this get fixed… last VirtualBOX version can not boot last Ubuntu LiveCD!!!
Just for that people that will tell me something about 32Bits and 64Bits… my CPU is only 32Bits (Pentium IV HT).
And for thoose telling me about Windows 7 permissions… i have also tried running VirtualBOX with permission elevation… as administrator… etc.
And i have seen something very weird!!! about VirtualHDDs been on different folders…
I open VirtualBOX without admin elevation… go to Manage Virtual Mediums… i drag & drop a .vdi and it adds it… but if i run VirtualBOX with admin elevation it does not let me drop any .vdi there.
Also worst, for some .vdi i must drag & drop them each time i run VirtualBOX because they dissapear from medium manager after closing VirtualBOX!!!
All this BUGs happen when running (at least under Windows 7) VirtualBOX 4.1.16 r78094 (the last one stable version when writting theese lines).
For a small instalation: sudo apt-get install –no-install-recommends virtualbox-4.1
