Run Windows 10 on Linux Mint using virtualbox

The screen of my portable is acting strange from time to time. 
Maybe the video controller has a problem ...
To be sure I do not loose anything from my portable, I decided to virtualize it and check to see if I could run this virtualized pc on Linux Mint using virtualbox.

Important: my portable runs Windows 10 - 64-bit, so in order to run the virtualized version I also need a 64-bit OS. I chose Linux Mint Mate 64-bit as host OS.

The test succeeded : I can run my Windows 10 64-bit portable in Linux Mint using virtualbox.

Here is what I did:
  • Virtualize the portable
    • (on my running portable I wanted to virtualize:)Using "VMware vCenter Converter Standalone" I converted my portable running Windows 10 64-bit to a virtual machine. The result was a vmdk file. I copied the files (vmdk and vmx file) on an external usb disk.
    • The software can be found at : https://www.vmware.com/products/converter
  • Download and install Linux Mint on a USB stick
    • (on a windows pc) On the internet, search for "Download Linux Mint 18 Sarah"
    • Download linux mint :
      • https://www.linuxmint.com/download.php
      • Download the Mate 64-bit version from one of the servers listed.
        I used the server in Europe > Netherlands > Triple IT
        (1.6 GB is being downloaded)
    • (on a windows pc) Burn iso to USB stick
      • Use UNetbootin to burn the downloaded ISO to a USB stick (USB stick needs of course at least 2 GB of free space)
        • [x] Diskimage  - ISO
        • Navigate to your download folder
        • select linuxmint-18-mate-64bit.iso
        • Type: USB-disk  E:\   [OK]
      • Alternatives for UNetbootin:
        see http://www.howtogeek.com/127377/the-best-free-tools-for-creating-a-bootable-windows-or-linux-usb-drive/
    • Start Linux Mint from USB stick
      • Boot the PC you want to use with the Linux on your USB stick
      • On some computers you can/need press F12 or Esc and F9   to choose the (USB) device you want to boot from.
      • If boot does not work, check bios.
    • Optionally change keyboard layout (Menu > Keyboard > Layouts > Add > Country: Belgium > Add
      Move "Belgian" above "English (US)" > Close
    • Download, install and start virtualbox
      • Start Terminal
      • Type "sudo apt-get install virtualbox-qt" to download and install virtualbox (this will take quite some time so be patient).
      • Type "virtualbox" in the terminal window to start virtualbox
        • Add and the virtual machine
          • Be sure the USB disk with the Windows 10 vmdk file is attached to your PC
          • New
            • Name : type some name e.g. vmWin10
            • Type: Microsoft Windows
            • Version: Windows 10 (64-bit)
              • Next
            • 2 GB Ram is sufficient
              • Next
            • [x] Use an existing virtual hard disk file
              • Navigate to the vmdk file on the external hard disk > Open > Create
          • Click on the Start (green arrow) (and wait at least 5 minutes ... it takes some time to start Windows 10 in virtualbox, but it works !
            P.S. In virtualbox, the Ctrl+Alt+Delete is replaced by right Ctrl+Del to login in Windows

    Using RDP (Remote Desktop) to connect to vmWin10


    • Configure virtualbox > Machine > Settings > Display > Remote display > [x] Enable Server (Server Port: 3389)
    • Configure virtualbox > Netwerk > Attached to : Bridged adapter (Name: enp2s0)
    • Enable RDP in vmWin10 : Control Panel > System > Properties > Remote Desktop > [x] Allow remote connections to this computer
    • If necessary : Disable firewall in vmWin10 (or allow RDP through) : Control Panel > System and Security > Windows Firewall > Turn Windows Firewall on or off 
    • Verify IP address of you vmWin10 : in Windows > Start > cmd > ipconfig
      Note the IPv4 address (in most cases something like 192.168.x.y)
    • On another pc on your network : start > mstsc /v:192.168.x.y (replace by ip address of your vmWin10)

    View photos that are stored on your Linux Mint Pc on your Android tablet

    How to view photos on a tablet (photos are stored on a PC)

    I currently use Linux Mint as desktop PC and an Android tablet.
    My photos are stored on the desktop PC, but I wanted to view them also on my tablet.

    This is what I did:

    1. On the Linux Mint desktop PC : download system-config-samba
    2. Start this program and click on the + to add a directory (in my case: /mnt/data/Our Pictures)
      1. On the Basic tab :
        1. Directory : /mnt/data/Our Pictures
        2. Share name : Our Pictures
        3. [x] Visible
      2. On the Access tab : [x] Allow access to everyone
        Note: If you want a more secure access, you can choose to allow access to specific users
    3. On the Android tablet: Go to the Play Store and Search for "smb client"; Download (and install of course) ES File Explorer File
    4. Start ES File Explorer
    5. On the top left click on the 3 horizontal bars to display the menu and choose "Network" > Lan
      Click on the + (New):
      1. Server: /Our Pictures e.g. 192.168.1.3/Our Pictures
      2. [x] Anonymous
      3. Display as : Our Pictures on my desktop PC
    6. Now if you click on "Our Pictures on my desktop PC" you'll see the files  on the desktop pc

    Down the mountain with my new Nokia Lumia 800 (Stabilized)

    How to turn a shaky movie made with a Nokia Lumia 800 into a much better (stabilized) experience.


    The video has been modified with the YouTube standard image stabilization because it's a very shaky film
    You can also watch the original to compare the result.
    Search for "nokia lumia 800 stabilizer" on youtube if the link does not work.

    P.S. The film is not mine, I just place a link to it from my blog. All rights belong to the person who originally uploaded the movie on youtube.

    Windows 7 startup slowly at home

    Windows 7 takes a long time to start at home


    Problem

    When I am not connected to the LAN at work, windows 7 takes a long time to startup while displaying "Waiting for the User Profile Service"

    Solution

    Thanks to Chris Buchanan, I have found the solution at http://www.chrisbuchanan.ca/Blog/Lists/Posts/Post.aspx?ID=17

    What you need to do is to change the Local Group Policy setting the max. wait time for the network ... to 0

    Procedure:


    1. Start  > gpedit.msc
    2. Computer Configuration > Administrative Templates > System > User Profiles
    3. Edit the policy "Set maximum wait time for the network if a user has a roaming user profile or remote home directory" to "Enabled" and set the value Wait for network for maximum (seconds) to 0.
    4. OK
    5. Close policy editor
    6. Then force an update of the group policy (gpupdate /force) (this worked only when I was connected to the LAN at work)

    Since I did this, the startup time decreased from more than 1 minute to 20 sec. on my Dell XPS 15z (Core i7) laptop.

    VirtualBox - Oracle VM - networking

    I had some trouble finding a working solution for running Oracle ( ovm3 ) in Virtualbox 4.1.8 on Windows 7 Professional 64-bit.

    After a while, I found this configuration works (at least the connection between Host and Guest) :


    1. After installing Virtualbox, an extra networking device appears : VirtualBox Host-only Network (1)
      (see Control Panel > Network and Inteternet > Network Connections > Change adapter settings)
      Host-only means you can only establish a connection between guest and host,  your guest will not be able to connect to e.g. the internet
    2. This adapter  (1)  has IP address 192.168.56.1
      (see Control Panel > Network and Inteternet > Network Connections > Change adapter settings > Select VirtualBox Host-Only network > Details
    3. Now change the settings of the virtual machine ovm3 in Oracle VM VirtualBox Manager:
      1. Select ovw3
      2. Click on Settings (and wait until the config is fully read)
      3. Click on Network and choose Adapter 1
        1. [x] Enable Network Adapter
        2. Attached to: Host-only Adapter
        3. Name: VirtualBox Host-Only Ethernet Adapter
        4. In the Advanced section I left the settings to their defaults:
          1. Adapter Type: Inter PRO/1000 MT Desktop (82540EM)
          2. Promiscuous Mode: Deny
          3. Mac address .....
          4. [x] Cable connected
    4. Start the virtual machine ovm3
    5. Configure the network settings as follows:
      1. System > Administration > Network
      2. Enter password for root
      3. Tab Devices : select eth0 and click on Edit
        1. Statically set IP address:
          1. Address: 192.168.56.56   (or another in range 192.168.56.x)
          2. Subnet mask: 255.255.255.0
          3. Default gateway: 192.156.56.1
      4. Tab Hosts: I entered the same IP (..56) for the current hostname (don't know if this is really necessary)
    6. Save this configuration: File > Save
    7. Go back to tab Devices , click on Deactivate and Activate to finalize the network setup 
    8. Now you should be able to ping 192.168.56.56 and 192.168.56.1:
      Applications > Accessoires > Terminal
      ping 192.168.56.56     ...  OK
      ping 192.168.56.1    ...  OK
      pinging other IP addresses won't work because we are using the host-only  configuration in VirtualBox.
    9. Test login OVM console:
      From e.g. Internet Explorer in Windows:
      http:192.168.56.56:7001/ovm/console
      Login as admin/Welcome1
    10. Test sql*plus
      In ovm3: start sql*plus and login as ovs/Welcome1@XE
      Also working :
      -  connect system/Welcome1@XE
      - connect sys/Welcome1@XE as sysdba
    11. Start Oracle Application Express
      http://localhost:8080/apex/apex_admin
      Login als admin/Welcome1 ... je moet onmiddellijk je paswoord wijzigen (Welkom9!)

    12. Login as sys/Welcome1
      Create a new database user:
      Database username: mvr
      Application username: mvr
      Password: Welcome1
      Create Workspace mvr
      Manage workspaces > mvr > Manage developers and users > create/edit user mvr en ken paswoord toe
      Use http://localhost:8080/apex to login workspace mvr username admin password Welkom9! .. lukt niet (ook niet als user mvr)

      Oeps ... I can't yet connect  to http://192.168.56.56:80/apex from Windows
      (Might not be needed anymore, because the cause was the firewall, see further)
      EXEC DBMS_XDB.SETHTTPPORT(8080);exec dbms_xdb.setListenerLocalAccess (l_access =>FALSE)
      ;
      Solution: Disable the firewall in ovm3 (or add port 8080 to the exception list)
      System  > Administration > Security Level and Firewall > Firewall: Disabled
      Now I can use I.E. in Windows to use   http://192.168.56.56:8080/apex
    13. Accessing APEX from SQL*Developer
      1. Tried but failed:
        Hostname: 192.168.56.56
        Port 1521
        SID: XE
        Got error:
        Status: Failure - Test failed: IO Error: The Network Adapter could not establish the connection
      2. Solution:
        In ovm3:
        1. /etc/hosts:
          Verify/add 
          192.168.56.56   wwwdevpc37d.as.local    wwwdevpc37d
        2. In listener.ora and tnsnames.ora:
          replace localhost with   wwwdevpc37d.as.local 
        3. tnsping wwwdevpc37d.as.local
      3. In windows:
        1. c:\windows\system32\drivers\etc\hosts
          Verify/add 192.168.56.56 wwwdevpc37d.as.local
        2. In sql*developer add a Connection:
          Connection name: test1
          Username:sys
          Password: Welcome1
          [x] Save password
          Connection type: Basis  Role: sysdba
          Hostname: wwwdevpc37d.as.local
          Port: 1521
          SID: XE





    14. Info Listener.ora :
      su - root
      su - oracle

      .
      /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh  (don't forget the point + space at the start of this line)

      locate listener.ora

      nano 
      /u01/app/oracle/product/11.2.0/xe/network/admin/listener.oralsnrctl status
    15. Finally got bridged network working. This way the guest machine also can reach the internet.
      (this works for me:)

      Make sure host and guest OS share the same network segment e.g. 192.168.1.*
      Use the correct interface in Settings > Network:
      In my case:
      Adapter 1 [x] Enable Network Adapter
      Attached to: Bridged Adapter
      Name: Intel(R) Centrino(R) Advanced-N 6230 (=my wireless network adapter of the host)
      Advanced (leave the defaults): Adapter Type: Intel PRO/1000 MT Desktop 58254OEM)
      Promiscuous Mode: Deny
      [x] Cable connected


      In the guest VM :
      Not a bad idea to record your ip address and hostname in /etc/hosts
      Assign IP address, gateway and DNS:
      System > Administration > Network
      Doubleclick the eth0 interface and fill out a static IP address, mask and gateway (same as your host)
      On the DNS tab, fill out the Hostname, DNS (same as your host or e.g. 8.8.8.8)

      File > Save
      Activate
    16. Nice link:
      http://devhub.fm/setting-up-an-oracle-11g-sandbox-dev-environment/
    17. Enterprise managerstart Oracle simply type “emctl start dbconsole” into the console .. does not work
      Probably because some environment variables need to be set correctly in emctl
      su - root
      su - oracle
      . ./setenv.sh
      locate emctl
      ... to be continued
