No need to covert the VDI file to RAW format. Just copy the vdi file into the local folder. For me, I will just put it at /root/testing.vdi
Step 2, Create a new VM in Proxmox
On the “OS” tab, choose “Do not use any media”
On the “Hard Disk” tab, choose “local-lvm”, as storage, Disk size is any size you want, for example, 8GB. Format, choose “Raw disk image (raw)”, On CPU and Memory, choose the same as the Virtualbox settings.
Confirm to create the new VM.
Step 3, Detach and Remove the Hard Disk
Say my VM ID is 109, choose Virtual Machine 109, Hardware, Hard Disk, choose “Detach” button.
At this point, the hard disk will be listed as “Unused Disk.” It still exists but is not attached to the system. To destroy it completely, select the Unused Disk and click Remove again; and confirm when prompted.
It is a problem I met since Virtualbox 5.0.4. I can not make the guest OS communicate with Internet or Host, even the IP address is correct. It is similar to the Virtualbox bug of bridged connection, which is fixed in Virtualbox 5.0.6. So, installed the latest version of Virtualbox on my Windows 7 64bit.
The guest OS is Ubuntu 14.04 64bit. I upgrade my installation to Virtualbox 5.0.6. So the following are based Virtualbox 5.0.6.
When I tried to run yum update to do a update, it can not connect to the repos. And the wired thing is it is using IPv6 address. And actually I don’t have IPv6 implement in my LAN.
The network adapter information as below, looks normal.
The first time I run the command of yum update, it said another app is currently holding the yum lock. I don’t know why, and saw no process in memory by top command. So I just delected the lock file /var/run/yum.pid.
VirtualBox is a must have on my Windows 7. I installed Centos 6 32bit and 64bit testing guest system in it. And also retired Windows XP. So, keep Oracle VM VirtualBox updated is very important. Here is a new release of VirtualBox 4.3.
VMM: more work on improving the emulation of certain MSR registers on certain host CPUs (e.g. bugs #12734, #12736, #12744, #12748, #12686, #12770)
VMM: fixed single-stepping for real-mode guests (VT-x without unrestricted guest execution) and some I/O instructions (bug #12636)
VMM: fixed a potential problem with COW pages if nested paging is not available
GUI: Mac OS X: experimental native full screen support for Mountain Lion and Mavericks (bug #12292)
GUI: Mac OS X: removed the mini-toolbar minimize button which doesn’t work under Mac OS X full screen mode anyway

VBoxSVC: fixed a segmentation fault on Linux hosts if a very long path exists under /dev (bug #12760)
API: fixed guest misbehavior under certain conditions if a storage medium was attached or removed at VM runtime
Windows installer: make the –silent parameter work again (bug #12764)
Mac OS X Networking: prevent local traffic (VM-to/from-host) from leaking to wire (bug #12750)

Windows Additions/WDDM: fixed divide by zero exception with multiple guest screens under certain conditions
Windows Additions/WDDM: fixed crashes with 2D video acceleration enabled (4.3.8 regression; bug #12745)

I am thinking about to have a try on VirtualBox. I did find the place to download at Hexxeh nightly build.
I download the virtualbox zip file. It is a image file.
For testing purpose, I need a CentOS 6.3. So I download CentOS DVD image. Installed it in VirtualBox as web server.
Note: The network of guest system is using bridged, which allow the guest access internet, and also allow the computer in Lan can access the guest system.
The installation is simple, no problem. I would like to share my experience I met later.
1) Prepare the network
Only lo, or loopback is active. I can not access Internet from the CentOS.
eth0 is not showing when I run ifconfig command.
VirtualBox 4.1.22 is the latest maintenance release or VirtualBox 4.1.
There are following changes:
VMM: fixed a potential host crash triggered by shutting down a VM when another VM was running (only affected 32-bit hosts and 64-bit OS X hosts, 4.1 regression, bug #9897)
VMM: fixed a potential host crash under a high guest memory pressure (seen with Windows 8 guests)
VMM: respect RAM preallocation while restoring saved state.
VMM: fixed handling of task gates if VT-x/AMD-V is disabled
Storage: fixed audio CD passthrough for certain media players
USB: don’t crash if a USB device is plugged or unplugged when saving or loading the VM state (SMP guests only)
RTC: fixed a potential corruption of CMOS bank 1
Mac OS X hosts: installer fixes for Leopard (4.1.20 regression)
Windows Additions: fixed memory leak in VBoxTray (bug #10808)
After upgrade my 4.1.20 to 4.1.22, no automatic upgrade from 4.1.22 to 4.2. You have to download the 4.2 manually and install it.
