How do I fix this, the Virtual Server was working before?
I try to start the container and error:

Code: 
Failed to allocate 1073741824 B: Cannot allocate memory

I try to view the container from the Proxmox console.
Can I find what the cause is, or do I have to reinstall the virtual server and the program to run on the virtual server host?

Ok, I think it was my Memory allocation of 1024MB.
I reduced the Memory to 32MB and the container sort of started.
The container went to the Ubuntu server install, however I have already installed and configured a program, so something's gone wrong.
Also, the container's install won't respond to me pressing the keyboard?

Anyways, question now is, how do I calculate how much memory can be allocated to Proxmox containers?
If the computer with proxmox has a 2GB memory stick
then container 1 could have 1 GB memory
container 2 could have 1 GB memory
container 3 and 4 could have 0 memory.

How do I check how much memory Proxmox reads on the memory stick on the computer? Is there a command?
Can I then read the allocated container memory that I set and add them up?

So, I changed the memory on the Ubuntu VM from 2 GB to 512 MB and now it runs.
But my question still is:
How does Proxmox manage the memory?
In Terminal I checked the computer's memory with command
Code: 
root@proxmox:~# free -m
             total       used       free     shared    buffers     cached
Mem:          1743       1705         37          0         10        149
-/+ buffers/cache:       1545        197
Swap:         4095       2257       1838

If the computer only has 2 GB, then how can the VMs have 512MB, 2.00GB, 2.00GB and 2.00GB, which totals 6.512GB, when the computer only has 2GB?
