Hi i'm new to proxmox, previously i've used KVM and managed to host game servers before in an accelerated manner, however there are a lot of options that are different in proxmox. I noticed proxmox uses debian while previously i used opensuse because of its ease of administration and recovery tools and options.

Assuming i only need a text based VM, what would be the best setting to use for display?

Other than virtio and virtblock, any other settings i can tick or use to increase the speed of VMs?

I'm currently using proxmox on 2 different udoos (intel and ryzen) to test setups and learn some of the new things i need, performance wise so far it is decent but despite using nvme SSDs offline VM transfers are very very slow.

Regarding only text display: use a serial console! Add a Serial Port (0) and select Serial terminal (0) as Display. Inside your Linux VM, make sure to set GRUB_TERMINAL=serial and add console=ttyS0 to the kernel parameters. Or run your Linux VM as a unprivileged container.

thanks, i'll give it a try. opensuse has extensive text only support.
 
You might want to set your VMs CPU type from "kvm64" to "host" so it can use all the hardware features your CPU offers. kvm64 will use reduced features so the VM might run on more different hardware for easier migration in a cluster.

thanks i've set this. I'm gussing kvm64 is equivalent to core2duo and/or atom?
 
yeah i know they are different, i was curious about how kvm64 differs to host CPU i.e. host CPU but with fewer instruction sets?
It kind of heavily depends on your actual host. Run Linux (or a LiveCD) with host and kvm64 and run cat /proc/cpuinfo on both and compare the flags (which indicate capabilities and instruction sets).
