Also happens on Ubuntu 16.04.1 64-bit with QEMU 1:2.5+dfsg-5ubuntu10.4.
I have the following settings added to instance xml config:
<domain type='kvm'
xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
<qemu:commandline>
<qemu:arg value='-net'/>
<qemu:arg value='user,hostfwd=tcp::2222-:22'/>
</qemu:commandline>
It looks like forwarding does not happen at all. When I try to connect
to guest instance, I get exactly the same results regardless of whether
sshd is running in that instance or not.

I think this is not a bug, but you are using the command line parameters
in a wrong way. When you use "-net user,hostfwd=tcp:127.0.0.1:1122-:22"
you are creating a *new*, second host network device which is not
connected to the guest NIC device that you specified. Please try to
avoid mixing "-net" and "-netdev" options. You should rather do
something like this instead:
-netdev user,id=unet,hostfwd=tcp:127.0.0.1:1122-:22 -device virtio-net-
device,netdev=unet

Do we got any solution for this issue ?
I am seeing similar issue for qemu-system-arm, I have tried with "-nic
user,model=virtio-net-
pci,hostfwd=tcp:127.0.0.1:31258-:22,hostfwd=tcp:127.0.0.1:47175-:443,hostname=xxx.com"
and also with "-net nic -net

Finally I found what was the issue. in the /etc/ssh/sshd_config after commenting the below lines I am able to ssh to the vm.
# grep -i LISTEN /etc/ssh/sshd_config
#ListenAddress 127.0.0.1
#ListenAddress ::
#
check your sshd config.

So is this now working for everybody with the correct ssh config (maybe
also check your firewall settings)? Could we close this ticket nowadays?
Or is somebody still having trouble?

Hello, I'm also experiencing such a problem, using qemu-system-x86_64
(hence the retitling of this issue). More information and output is
available at http://issues.guix.gnu.org/48739, but basically with the
following QEMU command used to run a VM:
/gnu/store/vbjfas8smw260r0qw1d5bbnh5hz08haz-qemu-5.2.0/bin/qemu-system-
x86_64 -kernel /gnu/store/0fylx9z8lzyrbdivqa2jzn574gk8lcjv-linux-

modprobe.blacklist=usbmouse,usbkbd quiet" -enable-kvm -no-reboot -object

image,if=virtio,cache=writeback,werror=report,readonly -m 512 -nic
user,hostfwd=tcp::3333-:22
Trying to connect to the VM which has its sshd_config set to:
Port 22
PermitRootLogin yes
PermitEmptyPasswords yes
PasswordAuthentication yes
PubkeyAuthentication yes
X11Forwarding no
AllowAgentForwarding yes
AllowTcpForwarding yes
GatewayPorts no
PidFile /var/run/sshd.pi
ChallengeResponseAuthentication no
UsePAM yes
PrintLastLog yes
LogLevel DEBUG
AuthorizedKeysFile .ssh/authorized_keys .ssh/authorized_keys2 /etc/ssh/authorized_keys.d/%u
Subsytsem sftp internal-sftp
The SSH client would hang with its last debug output being:
debug1: Local version string SSH-2.0-OpenSSH_8.6
Inside the guest, /var/log/secure doesn't show any activity so itd
oesn't seem to be reached.
Ideas?

That's rather embarrassing, but the problem with my VM was that it was
lacking networking support. I turned this (too) minimal example of a
Guix System:
;;; file: os.scm
(use-modules (gnu services ssh)
(gnu system)
(gnu tests))
(simple-operating-system
(service openssh-service-type
(openssh-configuration
(permit-root-login #t)
(allow-empty-passwords? #t)
(log-level 'debug))))
Into:
;;; file: os.scm
(use-modules (gnu services networking)
(gnu services ssh)
(gnu system)
(gnu tests))
(simple-operating-system
(service dhcp-client-service-type)
(service openssh-service-type
(openssh-configuration
(permit-root-login #t)
(allow-empty-passwords? #t)
(log-level 'debug))))
After which using the '-nic user,hostfwd=tcp::3333-:22' allowed me to
SSH to localhost port 3333 successfully. Closing!

I have had the same problem, I tried logging into a buildroot image that
was started using the following command line:
qemu-system-i386 -drive
file=output/images/disk.img,format=raw,index=0,media=disk -vga std -nic
user,ipv6=off,model=e1000,mac=10:10:10:10:10:10,hostfwd=tcp::4000-:22
The ssh connection was picked up, but nothing happened. The problem was
that the network device was not brought up! I added the following to
/etc/network/interfaces
auto eth0
iface eth0 inet dhcp
And voila, I can use
ssh username@localhost -p 4000
to log into the machine using ssh.
