[SOLVED] Can Ryzen 7 3700U run smooth on Proxmox?

[Dogs1985]

Saw a mini PC with a Ryzen 7 3700U. I know that this processor is outdated, may this device consider small power consumption but big processing power?

My main purpose is to install OpenWRT on the Proxmox as a Internet router. May simply learn docker, container and linux, use the virtual machine to test weird application, and host some simple application like storage, adblock, wireguard, stream and etc.

Can this mini PC do it? Or Proxmox needs a lot of memory to run smooth for each VM?

Another stupid question, if installed OpenWRT on Proxmox suddenly crash, does it will affected whole network? Can I just restart the mini PC to solve it? Or is there another method to do it without restart whole machine? Or the probability of OpenWRT crash very low?

RAM is usually what will run out first. And with mini PCs you usually only got two SO-DIMM RAM slots and you want both populated to make use of dual channel. So it's not that easy to add more RAM later. You would need to remove your small RAM modules and replace them with bigger ones.

Some years old isn't bad. At least you then run into fewer problems, as the drivers are more mature and the hardware in general is better supported by the linux kernel.

Yes, when there is a problem with that OpenWRT guest you will be offline until you fit that problem. Have a look at OPNsense or pfsense. They allow you to run two high available OPNsenses/pfsenses so in case one will stop working the other one will take over its job within a second. Of cause most useful when running two servers for real redundancy: https://www.thomas-krenn.com/en/wiki/OPNsense_HA_Cluster_configuration

Thank you very much for your reply, your reply really enlighten me a lot.

what makes you think that this processor is outdated?

>Can this mini PC do it?

sure.

>Can I just restart the mini PC to solve it?

you can just restart the OpenWRT VM

This is a processor from a few years ago, maybe there is a cpu, memory or storage limitation, or lack technology to support, Plus it's a low power mobile/notebook processor, That's why I'm afraid it can't handle the VMs on Proxmox. Now know that this processor can handle it without problem.

Thought that Proxmox would not be able access once it crashes? Or does OpenWRT itself have a restart mechanism when crashes?

 

[RolandK]

if you want something like qutomatic vm/service restart on crash, there are different ways to handle that. this can be one of it:

Sorry for disturb again. How about the Intel celeron N6005, is it possible run smooth on Proxmox.

I don't understand, is the Proxmox use some kernel version on hardware Intel celeron N5105/N6005 will have problem? Switch the system kernel can done in Proxmox? I don't know anything of this.
Are you facing some problem on your device? You don't recommend me use this Intel celeron N6005 as Proxmox?

Virtualization on them is unstable. Newer kernels do better, but seems still not good/optimal for many people.
So if you want (now) a stable system for your PVE-host, I would not recommend those CPUs (yet)...
