Imported VirtualBox Virtualized Service does Not boot

After importing a VirtualBox Virtualized Service, sometimes it does not start and shows the following screen.

When starting, the startup.nsh shell reports us that any EFI boot file is found.

We can solve that by adding the EFI boot file path as follows, for example for a MacOs VirtualBox type the command:

bcfg boot add 0 FS3:\System\Library\CoreServices\boot.efi “MacOS”

The File System could be FS0 , FS1, FS2 …. depends on your machine.

If your keyboard is not english, for example in a spanish keyboard use the following keys to type the previous command:

( ç for \) (SHIFT ñ for : ) (SHIFT ¨ for “)

Restart the virtual machine and it will run if the boot.efi path is correct.

If necessary you can delete the 0 entry by typing:

bcfg boot rm 0

We can move if necessary the order of the inputs, for example move the 0 to position 3:

bcfg boot mv 0 3

How to measure the electricity provided by a solar panel on-grid

Many of us have installed a solar panel connecting it through a microinverter to a plug in our home electrical network.

In an on-grid solar system, the photovoltaic panels are connected to the utility grid.
During the day, the solar modules supply your home with electricity.

Actually this is an on-grid photovoltaic installation.

For this I used a microcrystalline solar panel and connected it to an Enphase IQ7 Microinverter.

The microinverter transforms direct current into alternating current


The problem was that after doing the installation I didn’t know how much electricity it provided , I didn’t even know if it works .
I tried to buy the specific measurement system to connect to the Enphase IQ7 microinverter, but it was very expensive.
So I installed a smart plug between the microinverter and the domestic plug to try to measure the current passing through it.

And it was effectively able to measure the electric current passing through it.

Energeeks 3.0 app

I could also connect the smart plug through WiFi to an application on my mobile phone (Energeeks 3.0) where I can see the electrical production at the moment and all the statistics of energy production.

How to use Windows and MacOS simultaneously on a Chuwi Ubook tablet

Chuwi Ubook tablets come with the 64-bit Intel Celeron Gemini-Lake N4120 processor, with 8GB of RAM and 256GB of SSD.
They bring Windows 10 pre-installed.


These features allow them to run simultaneously Windows 10 and MacOS with enough agility to work comfortably.


As we have said Windows 10 comes pre-installed, then we only have to install MacOS on a virtual machine inside of the tablet so that they can run simultaneously.


Make sure you have a license to use both operating systems.


To do this you can download the Mac OS from Apple’s website.

I recommend the last steady one, MacOS Catalina.

Also you can download it from here or from here

As a manager of virtual machines we will use VirtualBox for Windows.

We can download it from here

First we install VirtualBox platform packages for Windows Hosts and then VirtualBox Oracle VM VirtualBox Extension Pack.

If you need you can see in this video How to install Virtual Box and its Extension pack Install Oracle Virtualbox 6, Extension Pack and VBoxManage on Windows 10

Now we open Virtual box and we choose Machine – New

We write the name that we will give to the machine, for example MacOS, and we choose type Mac Os X and version 64-bit

and we click next

Now as memory size we tipe 4096

and we click next

Now we choose Create a virtual hard disk

and we click Create

Now we choose as hard disk file type VDI

and we click next

Now we choose Dynamically allocated

and we click next

Now we choose de file location and the size, I recomend 120GB

This is the maximun size the disk could ever have.

and we click Create

Now we must configure the machine

we choose Machine Settings

We click System and unselect Floppy (cause the Ubook hasn’t any floppy)

Don´t click Ok, now we click Processor and whe choose 4

Don´t click Ok, now we click Dysplay and we choose 128 MB

Don´t click Ok, now we click USB and we choose 3.0

Don´t click Ok, now we click Storage and we Choose a disk file,
the one we downloaded previously macOS_Catalina.iso

Finally we click Ok

Now we choose File – Exit (to close Virtual Box)

Having Virtual Box closed we open in Windows a command window by typing cmd

Inside the Windows command window, we copy and paste the following comands

(For Ubook X 12″ whith graphic resolution 2160×1440)

cd "C:\Program Files\Oracle\VirtualBox"
VBoxManage.exe modifyvm "MacOS" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
VBoxManage setextradata "MacOS" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac19,1"
VBoxManage setextradata "MacOS" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0"
VBoxManage setextradata "MacOS" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Mac-AA95B1DDAB278B95"
VBoxManage setextradata "MacOS" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
VBoxManage setextradata "MacOS" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1
VBoxManage setextradata "MacOS" VBoxInternal2/EfiGraphicsResolution 2160x1440

(For Ubook 11.6″ whith graphic resolution 1920 x 1080)

cd "C:\Program Files\Oracle\VirtualBox"
VBoxManage.exe modifyvm "MacOS" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
VBoxManage setextradata "MacOS" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac19,1"
VBoxManage setextradata "MacOS" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0"
VBoxManage setextradata "MacOS" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Mac-AA95B1DDAB278B95"
VBoxManage setextradata "MacOS" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
VBoxManage setextradata "MacOS" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1
VBoxManage setextradata "MacOS" VBoxInternal2/EfiGraphicsResolution 1920x1080

Now we open Virtual Box again and we run our new virtual machine

Now if the system asks for the ISO to run whe choose the iso we downloaded macOS_Catalina.iso

The system take it´s time to run an finally the apple shows up

Now we choose our language, choose yours, I will choose Spanish
then the system ask for MacOS utilities, choose Disks Utility and click ok

Now we choose the 120 GB disk we made for the system, and click Erase in order the system could format the virtual disk

Once we have a drive to install Mac we come back to the previous screen an we click Install MacOS and then continue

The process of installation could take long time, restarting the machine several times
Now we click Acept

Now we click on the hard drive and install

Then choose your country an then continue

Now you choose language, click continue

Continue again

At ID Apple we choose configure later

Accept the conditions

Set user and password

Click continue in the express configuration

Continue … Continue … Continue until the end .

Because Ubook is a tablet I recommend you enable the Virtual Keyboard on Mac OS.
Go to the Apple menu then open System Preferences
Go to “Keyboard” preference panel, and then choose the “Keyboard” tab
Check the box next to “Show Keyboard & Emoji / Character Viewers in menu bar”

I also recomend you to make a Shortcut to the Virtual Mac machine
and move it to the Windows tools bar to open the machine and
change easily with one click between Windows and Mac

Et voilá this is how your CHUWI UBook Tablet looks now

I recommend once the MacOs virtual machine is installed, do not make the updates that MacOS proposes, because on many occasions after the update the system does not start and it is necessary to install it again.

Updating WordPress directly -(without FTP)-

If we want to avoid that when we try to update WordPress or any plugin, WordPress asks us for the credentials to update by FTP, we only have to add a line to the wp-config.php file. For this we open a terminal.

In the terminal we type the following command to edit the file wp-config.php: sudo io.elementary.code /opt/lampp/htdocs/wordpress/wp-config.php

Now we add the line:

define(‘FS_METHOD’, ‘direct’);

So it shows like this

/** The Database Collate type. Don’t change this if in doubt. */
define( ‘DB_COLLATE’, ” );

/** Para que no haga las actualizaciones por FTP. */
define(‘FS_METHOD’, ‘direct’);

/**#@+

We save the file and from this moment the WordPress update will be direct, without FTP.
