BUG: RAM won't overallocate, easily fixed, but considering options!

I'm trying to run but i got this error Unable to init server: Could not connect: Connection refused qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory QEMU 5.2.0 monitor - type 'help' for more information (qemu)
Can anyone help me?
I am trying the start OSX with this command
sudo docker run --device /dev/kvm --device /dev/snd -v /tmp/X11-unix:/tmp/X11-unix -e "DISPLAY=${DISPLAY:-:0.0}" sickcodes/docker-osx:latest

@C9-Dev I am also getting this Issue, it is because the default RAM is 8GB, and in this case, the server has BELOW that amount and kills.
I am updating the image now, perhaps 90% of MemTotal's 8152908 kB
?

90% ram
echo $(("$(head -n1 /proc/meminfo | tr -dc '[:digit:]') / 900000"))
RAM=${RAM:-$(("$(head -n1 /proc/meminfo | tr -dc '[:digit:]') / 900000"))}000 \
exec qemu-system-x86_64 -m ${RAM} \
Or shall I set the default RAM to 2000 as that's the bare minimum anyway?
Hi, I'm still getting same issue

I've checked /dev/kvm permissions, xhost +, and if user in groups of libvirt, docker and kvm groups.
I'm not running in root account either.
I'm using these images
user@pc:~$ docker images

How much RAM do you have
@sickcodes i have 16GB size rams
Try now since I changed f6e0bfa
Default RAM is 3GB, you can change to something like 5 or 10 because it will use all of it
-e RAM=5 \
Another suitable candidate for increasing available RAM:
sync; echo 3 > /proc/sys/vm/drop_caches
Which clears your memory cache.
I removed RAM=max
and changed the default to 3
export RAM="$(("$(head -n1 /proc/meminfo | tr -dc "[:digit:]") / 1000000"))"'
^This causes RAM creep. I left an idling machine on for 10 hours and I used about 16 of RAM by the end of it.
2GB is also slightly too small and causes mouse freezes (personally experienced, and seen in #207)
