Hi, I am Karlis, I manage small server/network infrastructure, our VMs are hosted on Xenserver. Some time ago we needed to redesign management and backup system for our VMs and we found XO. Now we are in process to upgrade our hosts to XCP-NG.

@Ascar In XO cloud means pool, "hamburger" means host. If VM is running, it belongs to host where it runs, and receives host icon, no matter where it is kept in stopped state. If VM is stopped, it belongs to pool if kept on pool shared storage (cloud icon), or to host, if on host's local storage (hamburger).

WinServ 2025 on xcp-ng 8.2.1, xcp-ng tools v.8.2.2 rc1. No additional roles, except Windows Admin Center preview installed. Uptime about 2 months. No conhost processes at all.

ISO works, installed already on 2 Ubuntu 22.04 VMs

Outgoing communication from management and xcp-ng hosts to Internet is not very dangerous, because hosts are the initiators. Generally I don't block it. You can monitor these connections or restrict to certain addresses.

@olivierlambert Done

Right now one of my CR jobs are stuck, symptoms are the same as with XO from sources.
XOA 5.43.2 (xo-server and xo-web 5.56.2)

Perhaps there is something with my environment but then why it is working with older XO versions.

@tts said in Backup jobs run twice after upgrade to 5.76.2:

Can we import the config from our XO from sources to XOA or should we setup everything from scratch?

Today I got XOA trial ready and imported config from XO-from-sources. Manually started CR jobs are working. Will test it with scheduled CR next couple of days.

@Ascar In XO cloud means pool, "hamburger" means host. If VM is running, it belongs to host where it runs, and receives host icon, no matter where it is kept in stopped state. If VM is stopped, it belongs to pool if kept on pool shared storage (cloud icon), or to host, if on host's local storage (hamburger).

Sometimes we want to try harder
Perhaps the confusing part is, if I go to https://xen-orchestra.com/ there is no download link. One could not realize, the download option is behind login. I'm only guessing.

@olivierlambert I believe, it is from here

Installed AD DS role on my test Winserv2025 VM and conhost processes are appeared and already gone from 7 to 10 in about hour. In the same pool Winserv2022 AD DC VM no conhost processes at all.

WinServ 2025 on xcp-ng 8.2.1, xcp-ng tools v.8.2.2 rc1. No additional roles, except Windows Admin Center preview installed. Uptime about 2 months. No conhost processes at all.

If you need to restore one DC from VM backup, this can help

I am using RSS reader, feed https://xcp-ng.org/forum/recent.rss
Not the most elegant three click solution to read new replies in watched topics, click on unread posts (open envelope icon), then on All topics button, it opens menu, there click on Watched topics.

@chaoticmaster I suggest to use xcp-ng tools
