@sebastian-roth I have deployed the dual image to a different machine and … surprise! You are right, the machine boot directly under W10, in the next appears the grub and the posibility to boot under Ubuntu.

I have found a link about NVRAM, I suppose that will be a lot of them but was the first entry in google :

Understanding UEFI variables: http://en.community.dell.com/techcenter/os-applications/f/4457/t/19589262

1- What all information is stored in UEFI VARIABLES?

All configuration setup, vendor information, language information, input/output console, error console, and boot order setting all these information are stored in these variables

 

2- How to get NVRAM variables

You can use UEFI bootable USB to boot the server. You need to have supported files which can give you UEFI shell once server boot from USB. Once you got the UEFI shell you can run UEFI command "dmpstore" to see the variable available in NVRAM. For more options or help just type “? dmpstore”.  If you have Linux installed before in same server in UEFI mode. You can access the EFI partition. Give this command in UEFI shell "FS0:" Now your “/boot/efi “partition is mounted. You can see the content of this volume using ls/dir command. "dmpstore -all > myvariables"  will collect all NVRAM variable to EFI partition. When you reboot your Linux box you will see this file in your /boot/efi location.

 

3- Analysis of variables

You will see lot of entries in the dump file. Variable name, access, data and many more. We will use this example:

Variable NV+RT+BS 'Efi:ConOut' DataSize = 36

This tells that Variable name is Console output which data size is 0X36 in HEX

. This variable is available at runtime (RT) and boot time (BS).

Runtime variable which are available after OS booted and boot time which are available before

OS boot.

4- Mapping of UEFI variables from BIOS to Linux OS.

You can see all these variables are mapped from Linux OS.UEFI variables are mapped through sys entry. Just see to this location /sys/firmware/efi/efivars . It will have all variables which was available in dump file.

All these variables depend on efivarfs kernel modules. If this module is not available you cannot access the variables. It is mounted as  efivarfs file system on /sys/firmware/efi/efivars.

@wayne-workman Nothing. the behavour is the same. I have restarted the apache too.

@wayne-workman No. I have only one server and one node. But the service is running.

In the develope environment I have other server, in this one I deleted 6500 entries and It works better.

This server have 7000 entries in the hosts table but only is used by 400-500 computers

After UEFI issue I have time to this XD

@wayne-workman said in FOG Server CPU usage 100%:

@fernando-gietz I was thinking about this - last time someone had this issue, it was the mysql max connections being hit.

Maybe one of the FOG updates or an OS update (especially likely with Ubuntu systems) wiped out our max connection setting.

Anyways, heres what might fix it:
https://wiki.fogproject.org/wiki/index.php?title=Troubleshoot_MySQL#Increase_maximum_simultaneous_MySQL_connections

Make sure to do the query in mysql AND to change the conf setting too so the change persists reboots!

I have increased the connections and the trouble follows
I have setup the mysql to log the slow queries and not appears nothing.

The problem is the apache and his activity, it reaches to 100% of CPU. If you see the capture of the browser activity, the problem begins when the browser tries to “Dibujar” (In english, Draw). I think that the browser must to draw all elements, visible and hidden ones.
If you see the membership page, you can see the list of the members, but the browser doesn’t show the members that are not in the group, to see them you need check the checkbox; then, appears all of them. This list is not create on-the-fly, the browser “drew” it before. In my case, the browser need to draw 7000 elements

@george1421 I have recaptured the image.

• Install W10
• Install Ubuntu 16
• Boot under W10 and run the bcdedit command
• Capture the image

No, any change. The only change was the bcdedit command (following the tutorial that you attached)

I have deployed twice the computer with the dual image and now the grub appears at the first time O_o

@Sebastian-Roth I am reading the info about UEFI. Very interesting!!! Now I know more about what is UEFI and how does it work.

I post the info of the different commands in my test computer:

@sebastian-roth I don’t know very much about UEFI, until now the hardware had legacy support and we worked in this mode. But, the new hardware which is coming only support UEFI, then we need to learn to work under this new mode Thanks for the link, I will read it … what a pain!!!

I am not using the new hardware, I don’t know which will be, and to test the UEFI I am using HP 800 G2 eliteDesk. This hardware have compatibility with BIOS legacy.

@sebastian-roth said in Dual Images windows 10 and Ubuntu 16 with UEFI:

So here we go. The boot order/list in real native UEFI systems is not on disk. So far we don’t capture the NVRAM state of a machine as far as I know. This is definitely something we need to add to the todo list. On Windows only systems it’s probably working out fine most times so we don’t see an issue. But for UEFI dual booting systems we need to find a solution.

We will follow with this … waiting…

I test the changes that @george1421 says and works fine.
The first boot goes direct to W10 but in the next one appears grub menu .

@sebastian-roth I forget say it I rebuild the grub from Ubuntu live CD

@george1421 Yes. You have understand all well

As @wayne-workman said me, I post the output of my dual system: W10 LTSB 2016 and Ubuntu 16.04
