I am using truenas with xcp-ng. two different hosts. I have a 10gib link connecting them. No swtich. I set 2 static ips so we can talk to each other. Pings works and connects fine with my nfs share for vm storage network share for nfs. If anything this is good enough because I just need the storage for my vms to lot faster than 1gb. When I try to connect to my 10gb link with xcp-ng "backup remotes"" inside of xen orchestra. Not xen center. I am not able to connect. When I switch the ip to my 1gb link it works fine. Haven't touched the network share only the ip address in the "backup remotes". How do I have it connect without internet access? I do have a sfp switch but not sfp +. The cards are Chelsio T520-LL-CR. Its a 50 port swtich with 4 sfp ports and I don't feel like buying a new switch just for 10gb. The product is end of life and was $800. So that's why I am connecting the 2 hosts together in my homelab for right now. I just upgraded both hosts. Lots of money have been spent for the new computers..

Is it possible to have a direct connection between the computers and set static ips and use the remote backup connection in xen orchestra?

What do you think might be wrong?

@olivierlambert Yes I do, they are all desktop linux vms.

I am using Xen Orchestra github below.
https://github.com/ronivay/XenOrchestraInstallerUpdater

I have many different Linux machines. They all have xe-guest-utilities installed.
I followed the xcp-ng docs below.
https://xcp-ng.org/docs/guests.html#linux

Ran it to install. On 2 test vms.
sudo apt install xe-guest-utilities-latest

Xen Orchestra show it has the tools installed. (Management agent 7.20.0-9 detected)

Problem Notes:
I am unable to copy my clip board to the machine or to my main pc.

Iso Tools Installing Notes Problems:
Linux Mint tools failed to install coming from the iso download .sh script.
I fixed this by putting in this below to install xe-guest-utilities-latest.

bash /mnt/Linux/install.sh -d $DISTRO -m $MAJOR_VERSION

This failed so I ran. Ubuntu instead.
sudo bash /mnt/Linux/install.sh -d linuxmint -m 20.2

sudo bash /mnt/Linux/install.sh -d ubuntu -m 20.2
It worked and installed fine.
Rebooted the vm.

Found a post below to make sure I am doing the copying correct. I found another post but I don't understand what is Linux with X or Wayland. Did some research and nothing.

How do I get clip board text copying to work on linux? I have tried Debian 10, Linux Mint 20.2. Nothing is working. What am I doing wrong?
