XCP-ng 8.3 betas and RCs feedback 🚀

eb-xcp

@yann Good catch. I tend to use net install when available, as it is faster than emulated iso on supermicro motherboards. When trying beta 2 install, I did use the network source by using xcp-ng-8.3.0-beta2-netinstall.iso.
To test things further, I used my backup server (Supermicro X10DRT-H, with E5-2630 V3) and disabled execute disable bit. Verified that 8.3 RC1 install gives the same error "Xen requires NX support" and ran beta 2 install from local media. This time 8.3 beta 2 was installed without issues and after a reboot I verified that execute was still disabled in the bios.

Anyway, it's better to have an option b) if option a) fails

As you wish, but I won't support option b) in any case, so I prefer to mention it

Yesterday I upgraded my 8.2 server by downloading the 8.3 rc1 iso file onto a USB stick. In general, virtual machines, iscsi storage, etc. everything worked without problems, but there is an interesting situation. Before the upgrade, the server was connecting to the internet without problems. For example, when I ping Google, I get a response, but now when I ping, it finds the IP address from DNS, but there is no response. I checked the gateway and DNS settings many times and did not see any problem. In this case, I could not install XOA either. Has anyone experienced such a problem?

@altikardes
I assume there isn't a VLAN configured, isn't it?

Anyway, sometimes it's better to do the "Emergengy Network Reset" (under "Network and Management Interface") and start to reconfig your network interfaces from bottom up.

@NoHeadroom

Yes, there is no vlan configuration. There was no problem with internet connection before the upgrade. I set the ip configuration as dhcp but the result is the same. I reset the network settings with "Emergency Network Reset" from the xsconsole section and made the necessary settings after the system was restarted but the result still did not change. (I tried both static and dynamic ip.)

@altikardes
what's the contens of /etc/resolv.conf ?

altikardes

@NoHeadroom

Hello again, the problem was related to a rule change on the firewall. I didn't feel the need to check it because it coincided with the time I upgraded. So everything is working now. Sorry for the false alarm.

Good news then

I have also successfully run a test install of RC1 on my lab. Everything seems to be working fine. The TLS issue also seems to go away (will also put a separate post on the topic concerned).

Good Job guys !

One thing I noticed :

I seem to get an error message

no crontab for root

while running crontab -e the first time.

Is that normal? Is it ok to run a cron job for root ?

Could be very well happen if you have a fresh install and no cronjobs in the crontab. Most distributions would put corn jobs in /etc/cron.d anyways and so does xcp-ng too. And the users crontab then will be created on the first edit.

I´d advise to rather use system crontabs in /etc/cron.d/, one dedicated to each topic you have (but that's rather unrelated to XCP-ng itself, just standard Linux sysadmin practice).

@bufanda @yann

Thanks for the tip ! ~~Anyway to delete the crontab created for root ? Or it is not required (since it is blank anyways) ?~~ (I should have just used crontab -ir)

@stormi

I also noticed that I get an option to "Upgrade" to RC1 from beta 2. This should technically not happen since I installed beta 2 in Legacy BIOS mode and am now installing RC1 in UEFI mode since the former would be deprecated.

Is that an error in installer or upgrade is possible ?

It's not exactly an error, but it's not very good either. This would fail at some point so don't attempt it. We suggested to add the detection of such situations, upstream, but neither them nor us had the time to implement it: https://github.com/xenserver/host-installer/issues/11

Here's a new batch of updates for XCP-ng 8.3 RC1. I hoped there would be less changes after a release candidate, but between our own fixes and the updates published by XenServer, the list is rather big.

The following names are build identifiers, which can differ from the actual RPM names.

Does this mean XOSTOR is ready to be tested in 8.3 ?

@stormi
I ran yum update a few minutes ago and got this:
warning: %triggerin(sm-3.2.3-1.1.xcpng8.3.x86_64) scriptlet failed, exit status 1 Non-fatal <unknown> scriptlet failure in rpm package sm-3.2.3-1.1.xcpng8.3.x86_64

The server started and the VMs seems to be running.
I'm not running iSCSI so i hope its OK

Not yet.

@stormi Updated a single lab with no problems.

I'm not sure if "pure positive" updates are meant for this thread, so I'll just report that, anyways .

@stormi For us, the openvswitch-2.17.7-2.1.xcpng8.3 update has definitively solved the problem of overlay networks that weren't working (thanks David M. for all your help and hard work).

Unfortunately, the sm-3.2.3-1.1.xcpng8.3 update seems to have broken something in our iSCSI sessions. We now have 3 sessions instead of the usual 4 (2 interfaces on the host to two controllers on the storage array).

We have a less-than-ideal configuration with a large, flat network ( we have a project planned to put everything back the way it should be) with interfaces named c_eth4 and c_eth5, as recommended in the documentation in such cases.

It seems that the new version respects the use of interfaces for one of the two targets, but not for the other, which uses the default interface.
