nginx web server on VM inaccessible to host

My laptop is running Ubuntu 14.10 desktop and hosting 14.10 server in a libvirt VM (set up using virt-manager). I installed it in minimal virtual server mode with only openssh-server. After installation, I could easily SSH into it and added nginx stable PPA and installed it as well.

Here's the problem: browsers say "the connection attempt was rejected." It's not a networking issue as I can SSH, but I can't figure out what could be. I didn't go anywhere near iptables or whatever it's successor is called, and it's entire network configuration is thanks to libvirt's default network DHCP.

Please feel free to ask about any configuration details you need to know.
