XCP-ng 8.3 betas and RCs feedback 🚀

olivierlambert

Thanks for your feedback @ravenet !

For your information, the connection error icon in "Settings"-->"Remotes" that appears when entering a wrong password once, then connecting anyway afterwards with the correct password is still present after all the 8.3 updates.

Is this an XCP-ng issue?

Thanks for your feedback @ravenet !

ill do firther testing later, in case issue is out-of-date firmware on the adapter itself being incompatible with the new driver. ill try and check the mellanox 5.9 changelog for firmware version requirements.

@ravenet @olivierlambert I have a 4Lx card on the way for testing...

One thing i have learned from testing various different 10G nics with XCP-NG that may be somewhat related to this is if you remove (or if a driver fails to load properly perhaps) a NIC that has the management interface assigned to it from a host, upon reboot the host will come up with no NICs present in XO or via xe pif-list, an emergency network rest will not restore them either, my only fix has been to re-install XCP-NG.

If you however first move the management interface to a different NIC before removing said NIC then everything will come up fine and if you have installed a different NIC it will be discovered no problem. I have tested this going from a Qlogic NIC to an Intel X520 and from an Intel X520 to an Intel X710.

I have today upgraded an very old Intel Server (S5520UR) running XCP-NG 8.1 to XCP-NG 8.3 beta with the latest beta ISO:

Server:

Intel S5520UR
Dual Xeon E5645
48GB RAM
Intel RAID Cotnroller
RAID1 73GB SSD for DOM0
RAID5 1100GB SAS HDD for Localstorage 2

As the Server was initially a XenServer 6.5 I had to change the partition layout with

touch /var/preserve/save2upgrade

The installation was running smooth, no error message.
I could manage local via CLI and via SSH but not via XO (commit a2c36) from sources or via Xolite.

server.enable
{
  "id": "a1886440-588f-4630-86b9-b1e888553a12"
}
{
  "errno": -111,
  "code": "ECONNREFUSED",
  "syscall": "connect",
  "address": "192.168.1.116",
  "port": 443,
  "originalUrl": "https://192.168.1.116/jsonrpc",
  "url": "https://192.168.1.116/jsonrpc",
  "call": {

    "params": "* obfuscated *"
  },
  "message": "connect ECONNREFUSED 192.168.1.116:443",
  "name": "Error",
  "stack": "Error: connect ECONNREFUSED 192.168.1.116:443
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1495:16)
    at TCPConnectWrap.callbackTrampoline (node:internal/async_hooks:130:17)"
}

I could start VMs and they seem to run as expected.

~~I have not yet stated to use yum update.~~

Today I have updated the host via yum update. Everyting runs smooth, however still no luck in getting a https connection to that host.

Any advise where I could look into? Wbserver configuration or firewall settings?

When trying to run :

yum install xcp-ng-updater

I get this error :

http://mirrors.xcp-ng.org/8/8.3/base/x86_64/repodata/repomd.xml: [Errno 14] HTTPS Error 302 - Found

Anyone else getting this ?

I have freshly installed from the link mentioned in the blog : https://xcp-ng.org/blog/2024/02/15/xcp-ng-8-3-beta-2/

UPDATE: This may be due to mismatch in System-time. I updated Time with Chrony and it worked. Maybe a co-incidence but its working not and the error is not re-producable for now.

TheFrisianClause

I would like to update XCP-ng 8.3 with 'yum update' but I am getting this error:

http://mirrors.xcp-ng.org/8/8.3/base/x86_64/repodata/repomd.xml: [Errno 14] curl#7 - "Failed to connect to 2a01:240:ab08:2::2: Cannot assign requested address"

What is the resolution to this? IPv6 has not been configured on the machine.

@TheFrisianClause
I did yum update and it worked. See if this post provide any clue? https://community.spiceworks.com/topic/2165339-yum-update-not-working-after-disabling-ipv6

moussa854

@gb-123
I can not find yum install xcp-ng-updater in the blog post at you mentioned try yum update

gb.123

@moussa854

I think it was to do with chrony not updating the time. There was a mismatch in system time.

TheFrisianClause

Well the problem is dat it sometimes goes over IPv4 and most of the time it does not.. It did the samen on 8.2 LTS as well.

TheFrisianClause

@moussa854 This did not help, I have not even enabled IPv6. As I upgraded the 8.2 LTS system to 8.3 Beta 2.

Tristis Oris

@TheFrisianClause try with another dns. I have similar problem at some networks.

TheFrisianClause

@Tristis-Oris Did it, same problem still. I don't understand why it tries to connect to a IPv6 address while it is not configured on the system.

Update 22.02.2023:

Without feedback I have returned this host to XCP-NG 8.1 and from this version I updated via recent ISO to 8.2.1 without any problem.

Access from XO from sources or https no problem.

It seems to be that this old host does not work with 8.3 beta for whatever reason.

olivierlambert

Have you enabled IPv6 out of curiosity?

Ajmind 0

@olivierlambert

No, I have not enabled IPv6.

Had the 8.3 beta it enabled by default?

olivierlambert

No, you had a choice during 8.3 install (IPv4 only, or v4+v6 or v6 only)

The was no choice option or dialogue!
(I had selected to upgrade the exisiting 8.1 installation.)
