The extended partition is in the way. The extended partition can contain other (non-bootable) partitions and was often used in the past because a MBR could only have 4 primary partitions. You first need to shrink/move the light-blue partition (sda2, which contains sda5) before you can grow sda1.

@leesteken thanks for your feedback, shrinking the blue part give a error

Maybe you need to move sda5 (swap) to the front of sda2 (extended) first? Or maybe it's a rounding issue and just leave 1 MB of space here or there.
Or just remove sda5 and sda2, resize sda1 and add a new swap partition. But you'll need to adjust the operating system inside the VM for the new UUID and/or partition number of the swap.

EDIT: There are probably better tutorials on the internet about this than I can explain here. It's not really a virtualization thing as this mostly applies to real drives.

there it was before - and some tutorial sayed to move to the end

it looks also it would belong to sda2 and not to sda1

I usually put the swap partition at the beginning to prevent such issues when resizing later. If you don't need more than 4 partitions, the extended partition is not needed.
I suggest you just remove sda5 and sda2, resize sda1 and add a new swap partition. But you'll need to adjust the operating system inside the VM for the new UUID and/or partition number of the swap.

As long as you have (several) backups, feel free to try different solutions.Personally, I found that running regular background backups with PBS can prevent a lot of stress.
