qemu user networking: forward non-localhost guest IPs to the host
I'm running a qemu VM in user networking mode and I'd like to be able to access forwarded ports from the host. Something like the following works well.
-netdev user,id=t0,hostfwd=tcp::9992-:9992
But my VM makes an internal bridge network and I'd like to be able to access IPs from within that network. According to the documentation, the following should work but there's definitely something missing
-netdev user,id=t0,hostfwd=tcp:10.144.0.2:6868-10.144.0.2:6868
After adding a network alias for virbr0 or lo (sudo ifconfig virbr0 add 10.144.0.2) that host and port may respond to the netcat utility, but I'm having trouble contacting the services on the other side.
Is what I'm attempting possible? Here's my full invocation:
/usr/bin/qemu-system-x86_64
-smp 1
-m 1024
-uuid 6780dc39-da5f-4dda-844c-59f81b1a3c4c
-pidfile cfdev-efi-state/qemu.pid
-enable-kvm
-machine q35,accel=kvm:tcg
-object rng-random,id=rng0,filename=/dev/urandom
-device virtio-rng-pci,rng=rng0

-boot d
-cdrom cfdev-efi.iso
-drive if=pflash,format=raw,file=/usr/share/ovmf/OVMF.fd
-device virtio-net-pci,netdev=t0,mac=52:7a:c1:64:44:26
-netdev user,id=t0,hostfwd=tcp::9992-:9992,hostfwd=tcp::9999-:9999,hostfwd=tcp:10.144.0.2:25555-10.144.0.2:25555,hostfwd=tcp:10.144.0.2:8844-10.144.0.2:8844,hostfwd=tcp:10.144.0.2:8443-10.144.0.2:8443,hostfwd=tcp:10.144.0.2:6868-10.144.0.2:6868
