Hi all,
after several months of inactivity I managed to update Xen Orchestra Appliance (Debian 9.9 based) but it does no more work due to connectivity issue.

Infact 'xoa check' reports:

Node version

• xo-server config syntax
• Native SMB support
• Disk space for /var
• Disk space for /
• XOA version
• Appliance registration
• Internet connectivity: { Error: certificate has expired

• npm version
• XOA status: not up-to-date, please run xoa-updater

I generated a new self-signed cert using the "troubleshooting ssl section" instructions

https://xen-orchestra.com/docs/troubleshooting.html#configuration

$ cd /etc/ssl
$ cp cert.pem cert.pem-old
$ cp key.pem key.pem-old
$ openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -nodes -days 360
$ systemctl restart xo-server.service

but it seems to affect only XO web interface.

Please let me know how to regenerate the correct cert or if I have to install a newer XO Appliance based on newer OS.

Thanks a lot in advance.

On this server we are testing XCP-ng 8.0.0. before going to production.

We have 2 RAIDs on this server: SSD (sda) and SAS (sdb).
XCP-ng installation (without asking) created a single LVM partition merging both disks.
We need to have two separated SRs, so (from XOA) we removed the single LVM SR: trying to create the new ones we got errors ("storage is in use").
We rebooted the server and suddenly appeared in XOA the "Host time and XOA time are not consistent with each other" error.
Now the server icon is orange and it is not fully manageable.
Please note that all servers attached to XOA have the same timezone (Europe/Rome) and all date/times are correct (even hwclock is synced with systime).

Any idea on what caused the issue and how to recover the server status?

Yes, you are right infact the old instances are halted and are temporarily kept till I am not sure the imported ones are perfectly working on new node. Unfortunately in the meantime I need a way to manage boths and it means xencenter or cli. Thanks for having pointed my attention to the duplicated uiids problem.

@olivierlambert said in XO does not show all VMs on a particular xs 6.2 node and other:

XO will work on older XS. The main issue could be related to duplicated uuids. Please open a support ticket so we could take a look remotely.

Yes, that's right, since such VMs were imported with "preserve=true" they have the same UUID and XOA shows only one of the two instances (sometime the old one and sometime the new one regardless of running state).
The issue is already known:
https://github.com/vatesfr/xen-orchestra/issues/4287

Is there a way to change VM UUID without cloning one of the two instances?

Please let me know if it's possible to perform VMs migration from xs 6.2 to a XCP-ng 7/8?

P.S. I don't know where to open a support ticket since I am testing the free version.

closed Detect duplicated VMs (same UUID on two hosts) #4287

I am not a XO expert but I am able to see there's a filter ... The problem of course is not the filter. If your reread carefully my post you can see that the problem exists also (and above all) with the running VMs that are not completely shown.

Thanks.

I am experiencing some problems using XO.

1. On a particular node (xs 6.2), named xen03, I have imported several VMs exported from an older node (xs 5.6) but XO only showed 3 not imported VMs. Moreover all non-running VMs were not shown as well.
   I tried to restart toolstack on that particular node (xen03) and SOME (not all) of the imported VMs appeared but not the non-running ones. No problems using XenCenter and no problems on other xs nodes. How to force XOA to reread the full VMs list from xen03?

2. When I start an export from XenCenter, it correctly shows the progress of the task but XOA shows always 0% till the end (100%).

3. Using XOA I am trying to migrate VMs from xen03 (xs 6.2) to xen07 (xcp-ng 8.0.0) but task does not start and I read no errors. Is it possible to migrate VM from xs 6.2 nodes to xcp-ng 8 ?

If you prefer I can split the thread.

Thanks in advance.
