Hardware requirements for VMs on Proxmox

[CouscousPie]

Are there any hard technical requirements for running VMs on Proxmox? I'm asking because I got the KVM error every time I started Proxmox, but the bios does not offer any virtualization settings. As I couldn't get any VM up an running, I wonder if there are hardware limitations to virtualization, but I would assume that this was not the problem.

The machine I installed it on was an ideacentre 510s-08IKL.

Documentation states

• Intel VT/AMD-V capable CPU/motherboard for KVM full virtualization support

So, I assume KVM is not a hard requirement for virtualization, right? Would the performance of virtual machines be unbearable for use as a daily driver? If somebody shared some experience of how severe the impairment by missing KVM is that would be highly appreciated.

I have not tested this recently, but: without "Kernel-based"-VM the Qemu can not utilize that kernel module. And "normal" software-emulation may be much slower.

Define your goal. Test it. If your VMs are fast enough for your use case then it is ok ;-)

Edit: please note that Containers/LXC do not have this problem...
