@DustinB, I like the CLI, because sometimes you don't have access to the graphic environment.

RE: A question for the creators of XO
Hi @john-c,
Thank you for your great tips.
As I said, I've heard that Java and JavaScript are insecure, but they also have some advantages that you and others have pointed out. For example, they have a large community of users and developers. Sorry, but I think that sometimes we don't choose the right path. For example, I'm sure that a professional PHP or Ruby developer can convince you that JavaScript is not the right choice for some projects. If PHP or Ruby were not good programming languages, then they would not have so many fans and everyone would use JavaScript. One of the reasons why JavaScript is so popular is that this language can be run by browsers. Something like a standard for the web. In my opinion, JavaScript like Windows operating system. It has capabilities and features, but the most important reasons for its popularity are its large number of users and ease of use.
My other question is, why is there no program under the operating system to manage XCP-ng? -
A question for the creators of XO
Hello,
Why is XO written in JavaScript? Why isn't it written in PHP, Ruby or HTML5 programming languages? Are PHP, Ruby or HTML5 programming languages not able to do this?Thanks.

RE: From VMware to XCP-ng
Hi @planedrop,
Thanks again.
Is there somewhere that compares Xen with VMkernel? I want to convince my friend to use XCP-ng. -
RE: A question for the creators of XO
Hello @olivierlambert,
As far as I have heard, JavaScript and Java programming languages are insecure. I don't know how true this is. I know VMware vCenter uses HTML5 in one mode, although some features are missing in this mode. -
RE: A question for the creators of XO
Hello @gskger,
Thanks again.
In my opinion, one of the mistakes that Vates made was removing the XCP-ng Center. Citrix XenServer still supports XenCenter.

RE: How do programs run on Xen hypervisor?
Hi @Teddy-Astie,
Thank you so much for your reply.
I think a hypervisor needs an operating system to work for now. VMware ESXi might also use a small operating system.
Where can I find how to implement a Xen PV Driver? -
RE: How do programs run on Xen hypervisor?
Thanks.
The Unikraft itself is written in the C programming language. Is it a platform through which to run programs in C\C++, Rust, Ruby, etc., and some programs like Nginx, etc., on Xen? What should someone do if they want to do this without using Unikraft? -

Hi @olivierlambert,
I want to know if it is possible to use Xen hypervisor as a platform for developing applications? -
How do programs run on Xen hypervisor?
Hello,
I've seen something like LING that run directly on Xen. What technology should someone know in order to write such a program?
Is it possible to write something like a plugin for XCP-ng?Cheers.

RE: Tips on installing XO
@Danp, Yes. I read.
These were questions that I had asked before and no one answered:
1- Should I run the commands as root or sudo?2- Which directory is suitable to clone XO? I want to clone it in the /usr/local/src directory and this requires administrative access.

RE: Tips on installing XO
Hi @Danp,
I did the following commands:# yarn global add forever yarn global v1.22.21 [1/4] Resolving packages... [2/4] Fetching packages... [3/4] Linking dependencies...

Then I rebooted the system, but XO is not running:
# ss -tupln Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port Process udp UNCONN 0 0 0.0.0.0:111 0.0.0.0:* users:(("rpcbind",pid=472,fd=5),("systemd",pid=1,fd=37)) udp UNCONN 0 0 [::]:111 [::]:* users:(("rpcbind",pid=472,fd=7),("systemd",pid=1,fd=39)) tcp LISTEN 0 4096 0.0.0.0:111 0.0.0.0:* users:(("rpcbind",pid=472,fd=4),("systemd",pid=1,fd=36)) tcp LISTEN 0 511 127.0.0.1:6379 0.0.0.0:* users:(("redis-server",pid=517,fd=6)) tcp LISTEN 0 511 [::1]:6379 [::]:* users:(("redis-server",pid=517,fd=7)) tcp LISTEN 0 4096 [::]:111 [::]:* users:(("rpcbind",pid=472,fd=6),("systemd",pid=1,fd=38))
The log shows me the following error:

What should I do if I want to completely remove XO and use the script xenorchestra_installer?

RE: Tips on installing XO
Hi @Danp,
I did:# sudo forever-service delete orchestra forever-service version 0.5.11 Platform - Debian GNU/Linux 12 (bookworm) Service orchestra deleted successfully
What is the next step? Should I run
$ sudo forever-service install orchestra -r "Current_UserName" -s dist/cli.mjs
command again? -
RE: Tips on installing XO
@Danp, according to the XO documentation I ran the following command:
$ sudo forever-service install orchestra -r "Current_UserName" -s dist/cli.mjs
Is this wrong?
