Hello,

Based on:

Unable to create master connection to host(192.168.1.3) , due to org.apache.xmlrpc.XmlRpcException: Failed to read server's response: Connection refused

Sounds like the management server can't talk with the XenServer host. A high level overview of what I would do in that situation:

- Login to CloudPlatform and make usre CP sees the XenServer host as "Up"

- Either with XenCenter or via SSH on XenServer identify the NIC used for the management network, as well as the IP address assigned to it (which will allow you to determine what network is in use for management communications).

- SSH to your management server, look at the connected NICs. One of them should be in the same network as the IP address assigned to your management interface on the XenServer. Next, try to se if you can talk between your management server and the host. A simple ping would be a good start, but also note you should be able to connect to port 443 between management and the XenServer host.

The above might not be enough to solve your problem but should at least put you on the good track.

On cloudstack management xen host does not exist

Network:

Public internet -> router (192.168.11.1) -> switch1 -> cloudstack management (192.168.1.2) and xen host xenbr1 (192.168.1.3).

Public internet -> switch2 -> xen host xenbr2

Switch3 -> Xen host xenbr3

Management server with one eth, xen host with 3x eth (xenbr1 - magement, xenbr2 public, xenbr3 for vm).

Ping/ssh can connect from management to xen

Xen host tcpdump -nn:

01:52:24.133187 IP 192.168.1.2.54520 > 192.168.1.3.443: Flags [S], seq 2969368408, win 14600, options [mss 1460,sackOK,TS val 2299282 ecr 0,nop,wscale 7], length 0

Ping:

Maybe need install cloudstack host agent soft to xen host ?

its not good ?

Sorry, I do'nt know what I was thinking when I asked that you check if the host shows as "up" under infrastructure, of course it won't, that's what you're trying to accomplish after all (add a host, duh!) . What I didn't really notice before and I'm noticing now is the error "received unknown parameters for command addhost" That seems kind of odd to me and after seeing that error, I'm not so sure anymore this is a network issue. Based on the above, it seems like "Conection refused" might be a poor choice of words to say the transaction couldn't be completed for one reason or another.

I'm really not sure where to start as far as "Received unknown parameters [...]", I'd like to suggest you open a ticket with Citrix Support for further assistance.

I don't have a lot of experience with Xen on Debian, only XenServer. With XenServer, CCP makes needed changes to a new host automatically, as its added. I'm guessing you will need to install an agent manually.
