The hostnames are unique, modeled after the following scheme:
1-2-3-4.domain.tld resolves to 1.2.3.4
As such, for any IP a CPVM (or indeed SSVM) might get allocated, then
you will need to have that kind of resolution working. If you don't have
too many IPs, then it might be worth defining A records as the above for
all of them, as you won't necessarily know which IP a system VM will use
(during the lifecycle of Cloudstack, as you create and delete them).

Hi Guys
Just a quick question, when specifying your console domain in the
general settings, you need to add an A record to said domains DNS zone
to point to the CCVM public IP, for it to be accessible and for SSL to
work accordingly. Now if you have more than one CCVM because you have
multiple zones, should you update the DNS A record to include the
additional CCVMs public IPs too? Or is having only one enough?

Hi Nicolas
On my working zone it shows the same:
root@v-47-VM:~# telnet public_ip 5900
Trying kvm_public_ip...
Connected to 41.72.146.218.
Escape character is '^]'.
RFB 003.008
Both my kvm hosts have the same qemu/libvirt versions too. The issue
seems to boil down to my routing. I tested other telnet ports such as
53 and 80 etc the all come back with no route error.
My existing zone, the one working is fully connected using public IP
addresses and zero private networking subnets. I created a new zone to
reconfigure my set up this time using private subnets, since its
recommended that way. I created a backlink connection between my three
hosts on the same private VLAN. But it turns out my private backlink
connection cannot reach the public network. So I now had to configure a
gateway myself and its supposed to route network from my private
subnets to the internet such as a ping to 1.1.1.1.
I believe this configuration might be the reason, because as soon as I
turn off the firewall "gateway" I can telnet successfully from the cpvm
but then the agents disconnects because if cannot reach the public
network.

Hi Granwille,
I see the RFB version offered by the VNC server is 3.8, and the CPVM
currently can handle up to 3.3. Can you compare on your working zone
the output of the telnet to a VNC working port? Is there any difference
on the qemu/libvirt configurations on the hosts from each zone?

Hi
Its running on the KVM server:
root@hostname ~ $ grep -w 5900 /etc/services
rfb 5900/tcp # Remote Framebuffer
rfb 5900/udp # Remote Framebuffer
root@hostname ~ $
I stopped the firewall and was able to connect to the VNC service from
the cpvm:
root@v-78-VM:~# telnet 192.168.50.3 5900
Trying 192.168.50.3...
Connected to 192.168.50.3.

Thank you, this helps a lot. I am going to see if white listing some
rules might work. And see if it works after testing.

Networking can get tricky, especially if you want to be too smart about
it, it will bite back.
Anyway, VNC port 5900, is that even listening on the hypervisor, what
is ss/netstat saying?
Try to find an existing port to test against. If that fails
check/disable the firewall on the hypervisor or on any firewall device
between management server and hypervisor.

Hi Nux
Thanks for the update. I ssh'd into the CPVM and when I run `telnet
HV_Private_IP 5900` I get no route error. But if I do this with my
working existing zone it works fine. So it seems my systemvms cannot
reach the VNC server but when I ping from cpvm to kvm private ip I get
a successful response, this makes no sense.
