As Oracle VM server does not include XWindows thus there is no Graphical User Interface.
So, from the browser of Host PC of VMware Workstation enter the following address

And, you would see Oracle VM Manager home screen
All the Best

Oracle VM Server from Oracle, Competing with other Visualization products, such as VMware
I planned to Install Oracle VM Server and Oracle VM Manager as a VMware guest, but when I researched on various forums and blogs including OTN, I came to know that “Oracle VM Server is a bare-metal product and that it cannot be installed as a VMware guest!”.
Failure to procure a spare machine and having some time to kill made me try and succeed in installing Oracle VM Server and Oracle VM Manager as a VMware Guest.
The following are the steps:-
Download Oracle Server and Oracle VM Manager from http://edelivery.oracle.com/oraclevm
Open VMware and select New Virtual Machine option. Select the option Typical for type of configuration.
Click next to go to the next screenSelect “Installer disk image file” option here and browse and select the iso file of Oracle VM Server you downloaded from the above link.
Click next to go to the next screenSelect “Installer disk image file” option here and browse and select the iso file of Oracle VM Server you downloaded from the above link.
Select Linux as OS
Select the Location where you want to store the Virtual Disk
Specify the maximum size of the disk
Click Finish
Oracle VM Server loads Press Enter to start the installation of Oracle VM Server
Press Skip
Select the Type of Keyboard
Press Yes to Create new partitions
Select the option Remove all partitions and press ok
Click Yes to confirm
Click Yes to Review and Modify Partition Layout
Click on the /OVS mount point and select Delete Goto the / partition select EDIT
Select the option Fill all the available space and press OK(If you go with the defaults then during the installation of Database XE the pre-requisites might fail, as it requires a minimum space of 2600 MB in the installation drive.)
Press OK on the partitioning page
Press OK on Boot Loader Configuration Screen
Select OK on Oracle VM Management Interface
Select Manual address configuration on the IPv4 Configuration Screen and specify the IP and Netmask
Set the Gateway and Primary DNS
Manually Set the Hostname
Set the Time Zone
Set the Oracle VM Agent Password
Set the Root Password
click OK to begin the installation
Select Reboot after the installation is completed
When the VM is restarting press enter to enter the GNU-GRUB to select the 32-bit option else you will encounter an error “ERR: Not a 64-Bit CPU!erver-ovs (xen-64-3 .1.3 2.6.18-8.1.15.0.16.el5ovs)’” as by default the Oracle VM Server boots as a xen-64-3 .1.3 2.6.18-8.1.15.0.16.el5ovs!
When you press Enter during reboot you will see the below screen, select the first option and press enter
You will be prompted for EUL Agreement, select Agree
Login with Username ‘root’ and its password.
Now you ready to use .. check out my next post about Oracle VM Manager,

Since I “work with computers” I tend to get asked to do fair amount of unofficial technical support for family and neighbours. I’ve noticed that the same confusions about IT crop up again and again. Here’s my top ten.
(Note that due to my background this is going to be Windows-centric. Please don’t take this to mean that I think Windows PCs are unfriendly – it’s just I don’t know enough about other systems to be able to comment. I also don’t want to come across as elitist – if non-IT people don’t understand something, that’s not because they’re dumb – it’s because we haven’t made computer systems obvious enough.)

| Keyboard shortcut |
Action |
| Navigation |
| Ctrl-A |
Go to the beginning of the line (note that if you use GNU screen, you can use the Home button to do this, especially considering that Ctrl-A is a special control character in screen). |
| Ctrl-E |
Go to the end of the line (note that if you use GNU screen, you can use the End button to do this). |
| Alt-B (or ESC, left arrow) |
Jump back one word using a non-alphanumeric character as delimiter. |
| Alt-F (or ESC, right arrow) |
Jump forward one word using a non-alphanumeric character as delimiter. |
| Ctrl-PGUP or Shift-PGUP |
This may or may not work, and it works differently on different console apps. It will either scroll up one line at a time, 1 page at a time, or it may not work at all. I’m inclined to think it’s not a bash shortcut at all. |
| Ctrl-PGDN or Shift-PGDN |
Same as the above but scrolling is done in the opposite direction. |
| Up/Down |
Previous/Next command in history. This one is way too obvious but I’m including it for completeness. |
| Ctrl-R |
History search. For example, Ctrl-R svn Ctrl-R Ctrl-R … will cycle through all recently run commands with the ‘svn’ in them. It is one of the most useful shortcuts in bash. |
| Command Line Manipulation |
| Ctrl-W |
Cut one word backwards using white space as delimiter. |
| Alt-BACKSPACE |
Cut one word backwards using a non-alphanumeric character as delimiter (different from Ctrl-W, for example, abc;bcd will cut to abc;). |
| Ctrl-K |
Cut everything forward to end of line. |
| Ctrl-U |
Cut everything backwards to beginning of line. |
| Ctrl-T |
Transpose the current character with the previous one. I almost never use this. Never mind, I never use it, but someone might find it useful. |
| Alt-T |
Transpose the word at cursor with the one before cursor. In other words, swap them around. |
| Ctrl-Y |
Paste whatever was cut by the last cut command. |
| Ctrl-V |
Insert the next character literally. For example, Ctrl-V TAB inserts the actual TAB character. This shortcut is often misunderstood because of mistyping Ctrl-V and not realizing what it does. |
| Ctrl-_ |
Undo the last command. Don’t forget – it’s Ctrl-Shift-MINUS, not Ctrl-MINUS. |
| Alt-R |
Revert all changes to current line. Very useful if you accidentally modify a command in history. |
| Alt-U/Alt-L/Alt-C |
Uppercase/lowercase/capitalize from cursor to end of word and move cursor past end of word. |
| Terminal control |
| Ctrl-L |
Clear screen while keeping whatever is already typed in the command line intact. |
| Ctrl-S |
Suspend currently running terminal. |
| Ctrl-Q |
Unsuspend the terminal suspended by Ctrl-S. You need to be aware of this shortcut because 99% of the time you’ve accidentally pressed Ctrl-S and need to undo its effects. |
| Ctrl-Z |
Suspend the currently running process (usually followed by bg to resume it in the background or fg to resume in the foreground). |
| TAB |
Autocomplete. Start typing, then hit TAB. You will either get a list of possible completion values (2 TABs needed) or the only choice will be filled in (only 1 TAB is needed). This shortcut is quite obvious and well known, so I put it at the bottom of the list. |

Hardware
Getting ram information
cat /proc/meminfo
or if you want to get just the amount of ram you can do:
cat /proc/meminfo | head -n 1
Another fun thing to do with ram is actually open it up and take a peek. This next command will show you all the string (plain text) values in ram.
sudo dd if=/dev/mem | cat | strings
Getting cpu info
Sometimes in troubleshooting we want to know what processor we are dealing with along with how much cpu is currently being used by our OS and programs. We can do this with these two commands.
