Installed a few weeks ago, using the Debian 12 template

I stopped at this point, let me know if you want more details.

$ sudo apt upgrade
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 xen-guest-agent : Depends: libxenstore4 but it is not installed or
                            libxenstore3.0 but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

olivierlambert

@AndreS have you followed the entire procedure? You must also run apt install -f

AndreS

@olivierlambert
No, I am used to stopping when I hit an error

All three show the new version of the management aganet after

apt install -f

ajpri1998

Tested with Ubuntu 22.04.4 LTS (Kernel 5.15.0-88-generic). Things are working well. Using XO Community 5fe53. Haven't updated hosts yet to November patches.

Management agent detects
Networking
- IP Address detects
- Can disconnect network
- Can create network device, IP Populates
VM Tasks - From XO
- Can Pause/Resume
- Can Suspend/Resume
- Can Reboot
- Can Migrate
- Can Snapshot

@olivierlambert all seems OK here too on a Debian11.

@olivierlambert when changes are made (like IP change in the VM), it is now instantly reported by XO
I will be able to go back to my work to integrate a BGP deamon to announce locals IPs to the network (I started last year to work on the xe-deamon but never had the time to finish it, and some months after I saw you blog post about moving to rust for it).

Thank you!

Install on Debian 12 VM went smooth. Tested on XCP-ng 8.2.1 & using Xen Orchestra, commit 5fe53. When changing networks it updates the IP very fast, but does not clear the previous IP addresses from the other networks. I did confirm they are not showing in the VM.

olivierlambert

Ah interesting Let me ping @yann about this behavior

yann

Hi @lawrencesystems, thanks for the feedback!

How are those IPs added and removed? In my tests I see old IPs always removed, whether I replace an address using ifconfig or whether I use ip addr del

lawrencesystems

@yann
I was simply changing the VLAN via the XO interface o the VM while it was running.

yann

@lawrencesystems do you mean you're changing the network the VIF is connected to? With old and new network both using DHCP maybe?

lawrencesystems

@yann
Correct, changed VIF and each network has DHCP and the VM is set via DHCP.

yann

@lawrencesystems thanks for those details, I could identify 2 specific issues from this, will fix that for 0.3.0:

Andrew

@olivierlambert I'm running it... It would be nice if you offered a debian compatible repository that I could just add to the apt sources so updates would happen along with other debian updates (like HP tools, node, yarn, etc).

yann

@Andrew that's planned

Hi everyone.

Issue is still persistent and can be reproduced.

After a reboot the old IPs are not showing up again until you change the network again.

Marc

EDIT:
Tested on fully patched XCP-NG 8.2.1 and XenOrchestra from Sources on commit 84650.

@olivierlambert Install on different Debian and Ubuntu versions works as decribed by others, so nothing exciting to add (which is good I assume ). XCP-ng 8.2.1 fully patched incl. the new security update candidates. XO from third party script with commit a3ea7.

yann

@itservices I'm working on it, though it's not fully ready yet.

Work in progress is available from this merge request. The "Merge request pipeline" block has download links to get a deb, a rpm, or a plain executable directly, for those willing to test.

Current proposed code should handle the "unplug" case just right, but the "replug" case still occasionally does not get the IP back - that part in the work but not yet ready to share.
