Router on virtual machine.

[lekto]

Hi, I’m planning to clean up my home networking. My idea is to upgrade my NAS, make router as virtual machine on NAS and give it some network cards through VFIO, which should simplify my current NAS, router, two switches and WiFi AP to just one machine and maybe WiFi AP. I tried this several years ago, but if I remember it correctly I came across chicken-and-egg problem: VM service needed working networking, but to get networking I had to run VM.
Is this problem still exist?
Are here people that run setup like this can say something on it?
Host would be systemd Gentoo and router on OpenBSD.

For me, I set up my host with a static IP, that would allow libvirtd to run and thus start up pfSense. This still isn't totally ideal as there's a race condition for additional services like named running in the other VM, but I just let it sleep for a while... perhaps it's time I moved named out of the VM.

lekto,

My bare metal hardware, that hosts my router KVM and the system I use for remote control of libvirt on the (remote bare metal) have a static IPv4 setup.
That lets the KVM start and me sort out the mess without going outside to the remote system.

It would be a very bad thing to depend on dhcpd running in a KVM to distribute IPv4 addresses to be able to connect the the KVM host to sort things out when its not working.

IPv6 is static, in the sense the addresses don't change but my ISP forces dynamic prefix delegation, so I don't have working IPv6 until ppp0 is up and my subnets have been delegated.
