I'm giving this presentation on TADDM for the NYC TUG today and the Philadelphia TUG tomorrow, and wanted to make it available online.

Accessing your Windows files from a Linux VM
At least in VMWare Workstation 6.5 (and probably earlier versions, tho I'm not sure) running on Windows, you can easily access any of your host OS files from any Linux VM. You just need to enable Shared Folders (from VM->Settings, in the Options tab) and specify the folders you want to have accessible from Linux. Once you do this, you should see those folders under /mnt/hgfs in Linux. So it looks just like a regular filesystem from the Linux perspective.
Note: I verified this with CentOS 5.

Adding disk space to a Linux VM in VMWare
I had a CentOS 5 VM that just didn't have enought disk space, so I wanted to give it some more. I didn't think it would be too hard, and in the end it wasn't, but it sure took me a while to find all the steps to accomplish it. So here are the ones I found useful. YMMV :)
Host OS: Windows Vista x64 SP1
VMWare Software: VMWare Workstation 6.5
Guest OS: Centos 5 (code equivalent to RHEL5)
1. Power off the VM (have to do this to add a new disk)
2. Create a new virtual disk (this is the easy part)
a. Go into VM->Settings and in the Hardware tab, click the Add... button.
b. Follow the instructions. This is very straightforward. I created a new 8GB disk.
3. Power on the VM and log in as root.
4. I decided to use the LVM subsystem, and that's what these steps address:
a. Create a Physical Volume representing the new disk: pvcreate /dev/sdb
b. Extend the default Volume Group to contain the new PV:
vgextend VolGroup00 /dev/sdb
c. Extend the default Logical Volume to include the newly-acquired space in the VG:
lvextend --size +7.88G /dev/VolGroup00/LogVol00
(The disk is 8GB according to VMWare, but it looks like around 7.88GB to Linux)
d. Extend the device containing the / (root) filesystem to stretch across the entire LV:
resize2fs -p /dev/mapper/VolGroup00-LogVol00
And that's it. I took the defaults on installing CentOS, so my / (root) filesystem is of type ext3, which supports this dynamic resizing.
So in this case, this disk is basically tied to this VM. If you wanted to create a disk that could be used by different VMs, you would certainly go about it differently, but that's a different topic.
