Sorry to ask so many questions, hopefully it can be a help to others in similar situations as well.

 

Running

Unraid : 6.0-beta4

Xen Version: 4.3.2

Dom0 Kernel: Linux 3.10.24p-unRAID x86_64

Motherboard: Gigabyte Technology Co., Ltd. - GA-78LMT-S2P

CPU: AMD FX-6100 Six-Core

Speed: 3.3 GHz

Cache: 128 kB, 128 kB, 2048 kB

Memory: 6144 MB (max. 8 GB)

Network: br0: - Duplex

eth0: 1000Mb/s - Full Duplex

vif1.0: - Duplex

Connections: 1

 

 

I have a machine that currently has 2x4GB ram in it.

From the unraid GUI / Info screen it says

Memory: 6144 MB (max. 8 GB)

Which seems slightly incorrect possibly?

 

From the terminal when I type the below, it shows that the system only has 3565MB of RAM? Any idea why the rest of the RAM isn't available?

 

root@Tower:/boot/scripts# xl dmesg | grep RAM

(XEN) Xen-e820 RAM map:

(XEN) System RAM: 3565MB (3651132kB)

(XEN) Scrubbing Free RAM: .done.

 

Also here is my xl list

 

root@Tower:/boot/scripts# xl list

Name                                        ID  Mem VCPUs      State  Time(s)

Domain-0                                    0  1278    6    r-----    4516.9

ubuntu                                      1  2048    2    -b----    259.1

 

 

Also stranger, if i run a regular free -m it shows

 

root@Tower:/boot/scripts# free -m

            total      used      free    shared    buffers    cached

Mem:          1130      1099        30          0        248        644

-/+ buffers/cache:        206        923

Swap:            0          0          0

 

 

If the mb has on board video some mb take ram for video memory

The motherboard does have onboard video, that would possibly explain why unraid info says there is 6144MB, but why would xen then say there is 3565MB and free -m say something completely different
