Hi @fabolhak,
You can modify the number of CPU cores and amount of allocated RAM in the extended properties of the virtual control within ctrlX WORKS.
To increase disc size, you will need to resize the user qcow2 drive image. Navigate to your virtual control directory and issue the following command in a command prompt.
qemu-img resize imageName.qcow2 +AdditionalMemory
Before the resize, the sda disk has 8GB of allocated memory.
After the resize, you can see the sda disk capacity has increased by 4GB to 12GB.
Once the drive has been resized, the partitions must be resized as well. It's up to you where you'd like to allocate the new memory, but as an example, you can grow the last sda partition to take up the new space. You can enter the virtual control shell using the default credentials (username:rexroot, password:rexroot).
sudo growpart /dev/sda 6
Now you can see the partition /dev/sda6 has grown to take up the new disc space.
