@stormi the LINUX OS under XCP-NG detects the cards but xcp-ng says that no ethernet was detected. Even after some emergency network resets.
Hardware is fine. As said, solved reinstalling, but this is not the first time, after upgrading it happened some times but solved with emergency network reset

After doing a yum update on one of my 8.3 RC1 server and rebooting, there were no ethernet cards detected.
It happened from time to time in older versions of xcp-ng but after rebooting some times and doing emergency network reset worked fine before. This time it didn't.
Finally I reinstalled RC2 from ISO.
I have two HPE (ProLiant ML350 Gen10), and the master is the one showing this problem, the other one doesn't show this problem.
Doing a yum update in the secondary server promoted to master worked as a charm.
Any ideas?

@tony I agree, but I think the most important is to start/stop a machine, the other can be done with XO

@danp hi I did it but, no network shares have been imported and neither backup jobs.
will try to reboot machine
Well Rebooting did the job, thanks @Danp

hi,
I've been having problems upgrading XO from sources 5.78 in my ol VM with Debian 9, so I tried a clean installation on Debian 11 and it works.
Is it possible to migrate all my backup jobs and configuration from my old VM to the new one

Thanks

@Kraken89 maybe you can try to attack the hard disk to an existing VM and try to boot?, I think in my case was that the template had PV enabled

@linhnb hi, I had similar problem in xenserver 7.0 old times. Did you use CentOS template??, try to create a new VM with windows server template or maybe ubuntu and attach the hard drive from CentOS VM, it will probably work.

@akurzawa Maybe there are snapshots involved? Have you tryed from XCP-ng Center? maybe there is a message you're not seeing

maybe you could provide a screen with job properties?

@jagdtigger hi, is quite usual that XO uses all memory, don't know why it happens and doesn't happen on XOA. My VM now uses 3GB of RAM and I programmed a reboot everyday on cron tasks before starting backups, works fine. Also noticed that when shuting down servers on powerfailure, takes around 30 minutes to shutdown XO VM with xe cliente, so I runt a ssh shutdown of machine and every works fine.

hi, take a look at the job properties, have you selected the target storage for backup?

hi, successfull upgrade from xcp-ng 7.6 to 8.0 here too, 2 hosts and 1 pool.

I'm with 5.42 and don't have this issue, planning to upgrade today, well tell you if I notice this error

done

@akurzawa hi, if you are using XO from sources latest version is 5.40

I hope XCP-ng will support legacy CPUs as I have E5-24XX series servers
I guess they will work fine but as they are not supported officially ...

@akurzawa hi, I've done it when installing patches before rebooting no problem so far, but as said here maybe is not a good practice.

Interesting, would you add packages like apcupsd?? I could use a standard PC to install it and do some test, we only have a production pool and few money

hi,
I worked with vmware ESXi for years then moved to xenserver since version 7.0, now I'm waiting for stable xcp-ng to move our servers I don't like the path citrix is taking
I'm also using xen orchestra for backups.
Oliver continue this fantastic job
