This is my setup:

I have a 160GB system drive that is split into three partitions:
75 GB : Windows Vista 64
75 GB : Ubuntu 7.04 64
10 GB : swap for Ubuntu

I'm in the process of trying to configure Vista as my host OS while virtualizing the Ubuntu installed on the second partition. I have followed the direction in the User Manual using the following commands:

Code: Select all

RAW host disk access VMDK file Bagheera.vmdk created successfully.

This part seems to work just fine.

I then open the VirtualBox GUI and access the Virtual Disk Manager. I use 'Add' to add my newly created .vmdk file. I choose the file and an entry appears in the HardDisk listbox.

Name: Bagheera.vmdk
Virtual Size: 152.74
Actual Size: 703B

Should not the virtual size equal the size of the partition? I am hesitant to try to start this VM because I am worried it may write on my other partitions.

Why not boot from a LiveCD with your VMDK attached and do a fdisk -l plus a R/O file system check?

No, that's fine (this also stumped me the first time I tried it). Virtual size is always shown as that of the whole disk but the guest OS will obviously only be able to read from / write to the partitions you've chosen.

Yup, but (77824+73232+6000)/1024 = 153.375 not 152.74. That's what got me puzzled.

Doesn't say anywhere his partitions are taking up the whole disk. If I do the same sum for one of my own disks it matches since I don't have any unpartitioned space.

Thanks guys, it seems to work fine! =)
