I'm having some trouble with a QEMU/KVM virtual machine on my local network.
I can connect to it from the LAN but not WLAN, despite the fact that these networks should forward to each other. This might be a router problem.
However, in order to diagnose this, I am trying to change the network type of my virtual machine manager.
At the moment it is set up to NAT, but I don't think this makes any sense.
I've used things like virtualbox before but I'm new to KVM/QEMU. I don't understand what either of these two things - KVM or QEMU, actually is in detail. The limit to my understanding is they're recommended for use with Debian 10 for doing virtualization.
I have a Debian 10 server setup on my local network and it has a Debain 10 system running in a virtual machine.
I attempted to change the network from NAT to bridged, and I appear to have broken it.
Here are two screenshots showing the changes I made to the network.
After these changes I can no longer start the VM. See image of error below.
Sorry for the totally noob question - I'm completely new (almost) to this stuff. I know I can manage my VMs with
virt-manager, but other than that I don't know of any other commands for configuring/diagnosing stuff.
The network was setup to NAT but I don't think this is a sensible/simple configuration. I use NAT on my router for externally accessible services but this is a seperate issue.
Is anyone able to point me in the right direction with this?
I should perhaps add the following question?
- How does KVM/QEMU work? Why does it require network "default" to be active?
