Important Things 1999

If you can’t find share folder under guest OS Ubuntu, maybe other linux, Just do it according the following sequence,

1. make sure your Virtual machine is powered off.

2. edit your virtual machine’s configuration to make a share folder, and enable it, for example, my host is Windows 7 Bit64, my share floder is C:\Test

3. power the Guest OS, for example, my Guest OS is Ubuntu 11.04, VMplayer is V3.14

4. IMPORTANT,  open a terminal, run “sudo vmware-config-tools.pl” , please don’t input ”

5. open places-Computer-Filesystem, under /mnt/hgfs, you will find the share folder. Congratulation!

It’s simple, isn’t it? Just re-config vmware-tools, heheeee

If it works, please give me a reply. Thanks.



I opened sync function of Zotero several days ago, because I use Zotero in Ubuntu 10.10 and Windows 7.

It works.

URL can be saved by Xmark, and web page can be saved by Zotero.

This is why I like Firefox.

I have read several articles about Chinese fonts setting under Ubuntu, the solutions they suggest are not suitable for me.

This is my setting for Ubuntu 10.10, the effect of Firefox is almost the same as IE6 under Windows XP.

I don’t believe VirtualBox is slower than VMware.

So, tested again tonight.

The process is following,

1. copy WinXP Guest from NTFS to EXT3

2. For VirtualBox, add Extension Pack, and reinstall new guest additions under safe mode. also, remove VMware tools.

3. boot VMware guest os

4. boot VirtualBox guest os

5. compare boot/reboot/shutdown time

The result is VirtualBox V4.0.2 is a little faster than VMware Workstation V7.0.2.

The reasons may be

1. In the first test, guest os was in NTFS, not local EXT3(my Ubuntu filesystem, not EXT4)

2. VirtualBox guest os had VMware Tools.

3. VMware is slower, because it used a longer time in BIOS.

VMware give me the feeling of real boot, slow, wait, see Windows, wait, wait, then you can use it.

VirtualBox is booting…., and ejected Windows XP, then it’s OK.

In fact VirtualBox is faster than VMware about 10 seconds during test of reboot.

sudo vi /boot/grub/grub.cfg

find      set default = “0″

in my Ubuntu, it’s line 13.

Change the number to number you want. For example, my Windows 7 is number 6(count from 0).

save

OK.

Just a recorder,

1. StarDict, with dictionary Langdao and Oxford

2. Firefox: Xmarks, Zotero

3. Docky

4. Ubuntu-tweak

5. Gimp

6. Filezilla

7. Movie Player, update to support AVI, RMVB

8. VMware worksation 7.1.3, and VirtualBox 4.0.2

9. 7zip

10. Freemind

11. ThunderBird: lighting, provider for google calendar

(Google calendar login, setting, share calendar, calendar detail, right click image “XML” for private address, copy link, paste into new network calender in lighting)

12. Wallpapoz, delete the background image it already set.

I just tested two virtualization software this morning, VMware workstation 7.1.3 and Virtualbox 4.0.2 under Ubuntu 10.10.

There are some strange things I can’t understand.

1. Both not support multi vCPUs very well.

2. 4-CPUs is obviously slower than 2-CPUs

3. 2-CPUs shows best performance, but only a little faster than 1-CPU.

4. VMware is faster than Virtualbox

Test enviroment:

Host: Ubuntu 10.10 updated, 4CPU, 4GB RAM

Guest OS: Windows XP with Office 2007, 1GB RAM, (1-4) CPU

After simple test, I decided to use VMware Workstation 7.1.3, but just for emergency.

During installation, I input a simple password like what I always used.

After finished update, when I wanted to change password back,  it said the new password is alike with the old one.

To solve this problem, just give root a password, then use root to change user’s password.

1. sudo passwd root

2. su -

3. passwd xxxx

4. exit
