NatVPS KVM / Tips & Tricks

TigersWay

Hi,
Wondering how some manage to use the new "nat-kvm" from NatVPS.... In France for now if I understood correctly.
The idea is not to complain, so far cpu and network are pretty good!

By the way I'm only a windows dev. so I'm far from a knowledgeable Linux user!

• Impossible to install anything from a CD (netboot.xyz, etc) => memory errors

• so, use of the "bullseye template", sorry I only know and work with Debian

  • impossible to install and then upgrade properly without a small swap, the memory is not 256 but 174MiB

• Finally Caddy and wireguard (i only need these) are working... But that was a lot of work!

Basic System Information:
---------------------------------
Uptime     : 0 days, 0 hours, 41 minutes
Processor  : Intel Xeon E3-12xx v2 (Ivy Bridge, IBRS)
CPU cores  : 1 @ 3392.294 MHz
AES-NI     : ✔ Enabled
VM-x/AMD-V : ✔ Enabled
RAM        : 173.8 MiB
Swap       : 128.0 MiB
Disk       : 3.9 GiB
Distro     : Debian GNU/Linux 11 (bullseye)
Kernel     : 5.10.0-33-amd64
VM Type    : KVM
IPv4/IPv6  : ✔ Online / ✔ Online

Anyone did better? Has any tips to share?

Reduce the size of the initramfs
create /etc/initramfs-tools/conf.d/compress with the content

COMPRESS=xz

reduce it further with

sed -i s,MODULES=most,MODULES=dep,g /etc/initramfs-tools/initramfs.conf
update-initramfs -u

Your service actually does have 256mb of RAM; the difference is because of how KVM virtualization works (having dedicated linux kernel rather than a shared one)

Don't worry, I never called anyone a liar... And after years and years playing with VPS I known and clearly saw every time that simple difference.
But it doesn't change the fact that in that instance the total of memory left I can use is then VERY short, and make it very difficult to manage that box, reason why I am not looking for explanation but for tricks

Mm, if there's a NatVPS LXC plan, you could apply/request for a transfer there. It would give you the full 256 MB.

@Ayyub , Any time table for other locations? Thank you.
