I am trying to SSH from my virtual image to the host system and get connection refused.

I have tried connecting to the systems' IP addr and the gateway IP addr for the virtual host.  Still connection refused.

I can SSH to my host from another with no trouble.

What am I missing?
1) Ping your host's IP address from the VM.
Pinging works fine.

2) Assuming it's pingable, look into what firewalld says, about the ssh port, and what IP addresses it's accessible from.
# firewall-cmd --list-all
public (active)
   target: default
   icmp-block-inversion: no
   interfaces: wlp1s0
   sources:
   services: dhcpv6-client ipp ipp-client mdns
   ports: 745/tcp
   protocols:
   masquerade: no
   forward-ports:
   source-ports:
   icmp-blocks:
   rich rules:

SSH is on port 745 (well not 745, but off 22).  I did the selinux command to allow ssh on this port and I can access from another system no trouble.

What is the output of "firewall-cmd --get-active-zones"


# firewall-cmd --get-active-zones
libvirt
  interfaces: virbr0
public
  interfaces: wlp1s0


And virbr0 is the one used for the QEMU.



So, if you do "firewall-cmd --info-zone=libvirt" do you have port 745 enabled?

No I don't

# firewall-cmd --info-zone=libvirt
libvirt (active)
  target: ACCEPT
  icmp-block-inversion: no
  interfaces: virbr0
  sources:
  services: dhcp dhcpv6 dns ssh tftp
  ports:
  protocols: icmp ipv6-icmp
  masquerade: no
  forward-ports:
  source-ports:
  icmp-blocks:
  rich rules:
    rule priority="32767" reject
