estevez, I made it and it went better than expected.
I have a single-node #Proxmox setup with various services in containers and a #HomeAssistant VM. For example, https://blog.randomplace.online/ is hosted there. I needed a #Widnows build machine to build a work project, so I decided to spin up a new VM.
I got 10 minutes of build time and my server didn't die during the build. You can see the CPU load of two builds. There is plenty compute power left to serve my blog for that one visitor per month. Also, the Home Assistant VM was not affected.
Need to mention that the node is an #ASUS PN41 with 4-core Celeron N5100 and 16GB of RAM.
