Hyper-V Tip - Will the "host" survive?

Question

Iron

Good evening! I'm very worried about one question. Previously, I did not come across virtualization, now it is a very interesting thing in the practice of it-specialists. There is a certain host.
Its specifications are:
CPU: 2x QuadCore Intel Xeon E5320, 1866 MHz
Motherboard: Supermicro X7DB8
RAM: 8GB
There is a separate PC proxyserver on ubuntu, and a mail server on ubuntu+postfix and wsus.
Question: do you think it makes sense to virtualize everything in one machine, on the host that I indicated above?
Will there be any problems with Hyper-V? Or with the host? Or maybe, for example, the host will pull the load, but do WSUS separately?
According to my calculations: 3GB and 2 cores per CD, 1 core and 1GB per proxy, and the same with the mail server. The rest is WSUS.
The office is not large, users up to 60 people, the load does not seem to be large.
What is the advantage of this idea:
+ energy consumption is less
+ backup with snapshots
+ centralized management
There is only one minus for me: if the host falls, I will have to work, but there is a spare server with the same characteristics. And from the "snapshots" everything is restored.
I would like to think about everything and plan correctly before proceeding with the experiments.
Thanks in advance.

Just don’t make a backup cd with a snapshot, and it’s not good to virtualize it
