For Virtual Box it is not recommended to use the power saving features of the guest OS as this will all be handled by the host. Therefore first thing when having installed my guest OS I disable this (including disabling the screen saver).

The appropriate way to save a virtual machines state (and resume later) is to coose Save the machine state when closing the machine from virtual box manager (here depicted for Windows XP).



This will free all ressources from the virtual machine. Next time we start the machine we will resume exactly at the same state where we saved it (like in suspend/hibernate from a real machine).

From command line this can also be done by

VBoxManage controlvm &lt;name_of_machine&gt;  savestate




Note on security: Mind that resuming from a saved state does not ask for authentication for the guest OS. In case we work with confidential data we therefore need to log out (or switch user) from the guest OS before saving.

What's the best way to pause my work in Virtualbox with Ubuntu as a guest?
This is my first post in this forum, so please, be patient with me.

I need to set my summary to show the sum of all rows in my grid, even the rows that are inside other pages - the absolute sum of values.

I was searching for it, and I saw a lot of people with this problem, so I don't think it is a problem with my code. It sounds more like a design in the grouping mechanism itself, otherwise I don't know.

But, to be clear, I think I need to make a call to server side to get the sum from there, is this possible? If so, how should I do it with json?

I was thinking about using the formatter option, but then it is triggered line by line, and I don't think this is the idea because the sum will come entire in the first call.

Any suggestions? 

Thanks !!!
