Memory unit size in GUI

[mir]

Hi all,

According to the GUI memory sizes should be in GiB (GibiBytes) but seems to actually be in GB (GigaBytes)?
It is correct for disks (GiB as in GibiBytes)
pve manager: 5.4-13

I have and example:
/etc/pve/qemu-server/128.conf
agent: 1
balloon: 2048
bootdisk: scsi0
cores: 2
cpu: Opteron_G5
ide2: none,media=cdrom
memory: 4096
name: mastodon
net0: virtio=3A:FC6:09:A1:37,bridge=vmbr10
numa: 0
onboot: 1
ostype: l26
scsi0: omnios_ib:vm-128-disk-0,size=50G
scsihw: virtio-scsi-pci
smbios1: uuid=ae6b6c26-82d8-42b5-92fb-d4702023c5eb
sockets: 1
vga: qxl
vmgenid: 841002d9-710f-4acf-98be-2529b5fdfdba

From inside the vm:
free -h
total used free shared buff/cache available
Mem: 3.8G 1.0G 275M 140M 2.6G 2.4G
Swap: 0B 0B 0B

free --giga
total used free shared buff/cache available
Mem: 4 1 0 0 2 2
Swap: 0 0 0

during boot of the vm, the kernel reserves some memory regions that are not accessible for the other processes
see the dmesg output of the vm
e.g. with 'dmesg | grep -i memory'

also doing 'free --mega' shows 4126 megabyte

Are you referring to this line?
Memory: 3960588K/4193764K available (14339K kernel code, 2370K rwdata, 4684K rodata, 2660K init, 5076K bss, 233176K reserved, 0K cma-reserved)

Looking at that line I cannot make that be 4 GiB?

Using free with default (free) shows total memory as 4030596 KiB
4030596 KiB is 3.84387588500977 GiB so this means the kernel should have reserved approx. 21MB unaddressable memory?
