@stormi
is there some information about that regression?
maybe i can help to test.
have a lab pool here with 3 hosts on a iscsi SR.

It was a missing python module import in the previous update candidate - so never went into production -, entirely our fault and easily fixed (but not so easily tested. You'd need to call the on-slave plugin with the is_open function on a VDI of the SR).

New maintenance update candidate (openvswitch, qemu, xen, microcode, xapi, Guest tools...)

Several package updates that we had queued for a future update are ready for you to test them. Some of them were already submitted to you earlier in this thread, and others are new.

The complete list is detailed again in this message.

xs-openssl:
- was rebuilt without compression support. Although compression was not offered by default and the clients that connect to port 443 of XCP-ng hosts don't enable compression by default, it's better security-wise not to support it at all (due to CRIME), and this will make security scanners happier.
- received a patch from RHEL 8's openssl which fixes a potential denial of service: "CVE-2022-0778 openssl: Infinite loop in BN_mod_sqrt() reachable when parsing certificates"
xcp-ng-xapi-plugins received a few fixes:
- Avoid accidentally installing updates from repositories that users may have enabled on XCP-ng (even if they should never do this), when using the updater plugin (Xen Orchestra uses it to install updates).
- In the updater plugin again, error handling was broken: whenever an error would occur (such as a network issue preventing from installing the updates), another error would be raised from the error handler, and thus mask the actual reason for the initial error. That's what happens when you write command with 3 m .
blktap:
- received a fix backported from one if Citrix Hypervisor's hotfixes, which addresses a possible segmentation fault if you create a lot of snapshots at the same time.
sm ("Storage Manager", responsible for the SMAPIv1 storage management layer) received a few fixes:
- We fixed an issue with local ISO SRs and mountpoints: creating a local ISO SR on a directory that is a mountpoint for another filesystem would unmount it. The patch was not accepted upstream because it touches legacy code that Citrix won't support, according to the developer who answered, but we considered it safe and useful enough to apply it to XCP-ng anyway.
- The (experimental) MooseFS driver will now default to creating a subdirectory in the mounted directory, to avoid collision between several SRs using the same share.
- The update also includes the followings fix from one of Citrix Hypervisor's hotfixes: CA-352880: when deleting an HBA SR remove the kernel devices
- Two other fixes which are hard to explain in user terms but typically don't affect the majority of users.
xen, microcode_ctl:
- Update the Intel microcode for IPU 2022.2
- AMD IOMMU fix
- Fix others issues like slow boot when VGA is enabled
Openvswitch:
- Open vSwitch ignores the bond_updelay setting for LACP bonds.
- Some packets might be dropped by a link after LACP renegotiation completes, but before bond updelay completes.
- The openvswitch logrotate script outputs spurious error messages into dead.letter.
qemu:
- If you add SR-IOV to a VM with GPU-Passthrough enabled, the VM doesn't boot.
XAPI:
- Add the other-config:ethtool-advertise option to the network commands. This option sets the speed and duplex of a NIC as advertised by the auto-negotiation process.
- Resolve other issues
XCP-ng Guests tools
- Integrate last changes from upstream
- Change the network interface to take in charge last releases with enX interfaces
- Support RHEL 9, Almalinux 9, Rocky Linux 9, Centos Stream 9...
- In the RPMs, switch the service to systemd by default and provide legacy RPMs for older systems with simply chkconfig. Not done yet for DEB packages.

What to test

Normal use and anything else you want to test. The closer to your actual use of XCP-ng, the better.

We also ask you to give a special attention to the updated guest tools for linux. We tested them on a large variety of linux systems, but we can't cover every special cases in our tests, so your help is more than welcome.

The installation instructions for the tools did not change: see https://xcp-ng.org/docs/guests.html#install-from-the-guest-tools-iso.

/!\ The only tools that were updated are those provided by XCP-ng through the guest tools ISOs. Tools provided by packages in the repositories of various Linux distributions are not maintained directly by us.

Test window before official release of the updates

No precise ETA, but the sooner the feedback the better.

I did a fresh install using "xcp-ng-8.2.1.iso". However after doing that it seems that I have no local storage. I do have a couple of error messages

More info:

I did install on a 500GB sata SSD previously used for other purposes
I have other sata and nvme drives in the system ZFS-formated, those drive are in use in case I boot the system as TrueNas store (SO NOT USED BY XCP-NG)
during boot I get following alarms:

EFI_MEMMAP is not enabled
fcore_driver CRITICAL TRace back most recent call File "/opt/xensource/libexec/fcoe_driver", line 34 CalledProcessError: Command '['fcoeadm', '--i] returned non-zero exit status 2\n"]

It seems that I have no local storage ..

I tried to add local storage ==> LVM creation failed

[12:16 Tiger ~]# xe sr-create name-label="LocalStore" type=ext device-config-device=/dev/sda3 share=false content-type=user
Error code: SR_BACKEND_FAILURE_77
Error parameters: , Logical Volume group creation failed,

Trying to fix the problems, I decided to update the system (as described in this tread, which did not solve the problems!

So, three questions:

is it possible to make an installer available for the actual test version, so that I can do an real installation using that installer !!
That would make testing easier and more realistic
how to solve the described problems
I would appreciate formal zfs support, as far as possible I use ZFS

@gduperrey Updated my two host playlab without a problem. Installed and/or update guest tools (now reporting 7.30.0-11) on some mainstream Linux distros worked as well as the usual VM operations in the pool. Looks good

Andrew

@gduperrey I jumped in all the way by mistake... I updated a wrong host, so I just did them all. Older AMD, Intel E3/E5, NUC11, etc. So far, so good. Add/migrate/backup/etc VMs are working as usual. Good for guest tools too, but mine are mostly Debian 7-11. Stuff is as usual so far.

gduperrey

@Louis,

The updates are unrelated to your issue.
You are welcome to start a new thread about it.
That way, rather than commenting in this thread, you will receive greater assistance from the community.

Did you look at the wiki's troubleshooting page to analyze your issue?
https://xcp-ng.org/docs/troubleshooting.html#the-3-step-guide

We don't see anything in your lsblk. Perhaps you could include the 'xe sr-list' result in your new topic.

Have you tried to create your SR using XOA or just the server's command line?

We don't offer an updated installer right now. Although we're working on a method to regularly and automatically build an updated iso. It will take some time before we can use it for the community.

As we know, ZFS is supported, some users use it. What exactly do you mean by zfs support?

Louis

@gduperrey

I did post here, because I am almost sure that I am facing serious bugs in the actual version. Of course I can be wrong, however I do think that the described problems are not related to things I am doing wrong. So it is more that I intended to make the team aware of the problems, then that I think I need help .....

Because I assume bugs, I did upgrade intermediately after the install, .... however, that did not solve the noted issues ...

I also installed Ubuntu in an VM on my windows10 system and compiled XOA. And tryed to generate storage from there, which not so strange, did lead to the same error messages seen before (I tried to define storage types EXT and ZFS).

Related to ZFS, I wrote that since I did read some were that it was not yet formally supported.

Note that my server does have disks installed (not intended for XCP-ng). The disks are ZFS storage pools active when I boot the server as TrueNAS server. That should not be a problem .... IMHO.
Note that I can not detach them, since it also involves NVME-drivers on the motherboard.
Also note that the SSD use for XCP-ng has been used for other purposes before probably including ZFS-partitions. I write that here because I noted people reporting issues related to disks previously used for ZFS.

@gduperrey
Applied on my test systems and all seems to be working well here.

@Louis There's no immediate evidence that the update candidates that this thread is about are related to your issues, so I second @gduperrey's request that you open one or more separate threads for your issues.

Expected feedback in this thread is something like : "I was on a fully updated XCP-ng 8.2.1 pool which worked well and then I installed the update candidates, and now I notice something doesn't work anymore" (regression due to the update candidates) or "I have tested this and that after installing the update candidates, and it looks fine".

AlexD2006

Updated and tested:

one single Host
lab-Pool (3 Hosts) - NFS Storage
lab-Pool (4 Hosts) - iscsi Storage

Everthing seems to work as expected.
(new VM, live-migration, snapshots, clone VMs, import/export VMs)

Ajmind 0

updated and tested:

test pool (2 hosts) iscsi storage
no problems so far.
(live-migration, snapshots, changed master in pool)

guest tools updated on
Debian 10 / 11 / Rocky Linux 8.5

AlexD2006

Sorry for my impatience.
Is there any news on ETA?

We are actually planning a maintenance downtime for firmware Upgrades and some other changes on a bunch of hosts and it would be cool do the updates on the same time slot to avoid double reboot/shutdown in short time.

Kind Regards
Alex

Ping @stormi

If no last minute issue is discovered with the updates, they should be released next week.

@stormi
Thx for your reply.
I try to wait so i can do it all in one Task.

Kind Regards

I am completely lost in relation to the way new software or updates are released.

If I download the actual file, I get exactly the same file as I used to get for months
there is an 8.2.1 which is not visual in the release overview
I would have expect that an update has the name 8.2.2 ........

So, I am lost .....

This is not a major release triggering a dot version update. This is a set of patches.

yum update

Louis

IMHO every set of patches should lead to a new version number and a changed initial download,
so if this is only a small update than it could be 8.2.1.1

My opinion of course but I would like to see a far more traceable update process
