Is anyone aware of a simple KVM and QEMU tutorial to create a virtual machine that can be assiged a static IP so that one can run a webserver from it.
I wanted to set up my webservers that are running in metal, into vms, and have them use the same IP addresses that the metal is now currently using. I'm not so sure why networking for the VM is so hard.
I've seen situations where servers even have multiple IP addresses assinged to systems with virtual network interfaces such as
eth0.1
eth0.2
etc. Sonic Walls do this.
Why do I need a whole networking wrapper for the VM. Can't I just assign the virtual network device inside the VM to the ethernet device on the metal, as you can will all the other devices, mouse, keyboard, tty, sound. The VM just maps this stuff as part of the VMs inherent ability. Why does networking require an entire wrapper virtual network?
I've been told the key to doing this is to build a bridge device (so we now have a who bunch of new devices). But I can't find any tutorials to do this, just a lot of confusing and, IMO, poorly written documentation.
I so miss the old days of Linux HowTOs
You can forward needed ports from host to vm
maybe this

with systemd now everywhere, it will be worth while to get something like this for artix
Solution 1: Using Distribution-Specific Scripts
RedHat Debian SuSE
Edit /etc/sysconfig/network-scripts/ifcfg-eth0
comment out BOOTPROTO
Add BRIDGE=br0
Create /etc/sysconfig/network-scripts/ifcfg-br0
The content should be:
DEVICE=br0
BOOTPROTO=dhcp
ONBOOT=yes
TYPE=Bridge
/etc/network/interfaces
# Replace old eth0 config with br0
auto eth0 br0
# Use old eth0 config for br0, plus bridge stuff
iface br0 inet dhcp
bridge_ports eth0
bridge_stp off
bridge_maxwait 0
bridge_fd 0
Start YaST
Go to Network Configuration
Add new device -> Bridge
Tick your existing network device
done
/etc/init.d/networking restart
The bridge br0 should get the IP address (either static/dhcp) while the physical eth0 is left without an IP address.
not if you need to use both, independenly. That is why you have these virtual network devices on the metal, so that you can access two different processes on a single real network device
