I’m operating a Proxmox server in a Frankfurt data center with an Intel Xeon E-2236, 32GB RAM, and 1.6TiB SSD, which is currently underutilized. I’m looking for a single trustworthy partner interested in using one or more VMs for non-resource-intensive, non-mission-critical projects to help share running costs.
I’ve never done this before, so if you have any advice on how to go about it, please share. If you are interested, get in touch!
While I think I have no use for that right now it’s IMO helpful to share what kind of an expense would that incur to your potential partner.
My monthly colocation bill varies with the cost of electricity. It currently stays below 40€, but that’s with a CPU near 1%. I think that, given the fact that I have paid for the hardware, a fair range would be between 25€ and 50€, depending on usage. Does this sound reasonable?
Sounds very reasonable, however with a total of 32GB or ram I don’t think more than a few VMs can be created in total. I have a similar setup and this is a constant bottleneck.
How much do you reckon those VMs would be? 3-4?
Since your usage is low, another idea is you migrate to a VPS and you rent the whole server out. You can charge a fix cost plus the electricity bill. It is probably easy to handle this way: You renting VM will be not competitive with the VPS vendors, and you can lower your bar for trustworthy.
I think recently someone has asked for infra tips in Europe. Your server could make a interesting option.
I am already running 7 VMs with substantial RAM to spare. It comes down to what the VMs are doing. It is true, however, that RAM is the (only) bottleneck in such a setup.
I am using xcp-ng and xen orchestra, only these two use somewhere 4GB out of the box. Even for a VM that does pretty much nothing you will need at least 2GB of ram.
For example I was running zulip and 2GB of ram were not enough for 2 users, I had to bump the VM to 4, so IDK, 32GB is a very low amount.
This may or may not be true depending on what the VM is doing. One of my VMs, for instance, hosts a Mikrotik RouterOS installation. That one could easily run on just 256MB:
All my other VMs are running Debian Bookworm, which theoretically can also run on 256MB. In practice, my Caddy server VM, my Technitium DNS server VM, and my Asterisk PBX VM each run comfortably on 1GB. Add to this 4GB for a smooth Proxmox operation, and you have 4 VMs requiring less than 25% of the 32GB.
You could save even more memory by going to a container base setup, like LXC, since you control all your infra, and all of them running on the same physical box using the same linux distribution.
