VMWare Virtual Machine Notes

I need somewhere to store my notes so this seems to be as good a place as any.



How To Remove Old Ubuntu Kernel Packages
Stolen from my Brother here : https://edwards.sdsu.edu/research/ubuntu-clean-boot-partition/#more-1599

First, figure out which running kernel you have:
uname -r
Do NOT remove that kernel!

Figure out which kernels you have installed
dpkg -l | grep linux-image | grep ii
Then remove them:
apt-get autoremove <package 1> <package 2>

Shrinking Virtual Machines To Use Less Disk Space
In virtual machine :
sudo apt-get -y autoremove
sudo apt-get clean
cat /dev/zero > zero.fill;sync;sleep 1;sync;rm -f zero.fill

Download vdiskmanager-windows from here :
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1023856
On the host :
vmware-vdiskmanager -k Ubuntu.vmdk
