XCP-ng 8.3 updates announcements and testing

ovicz

@flakpyro I did what you said about clearing certs and reinstall them, still no go.

dinhngtu

@ovicz No UEFI mapping displayed in the shell suggests that the VM couldn't detect its disks. Is your SR doing OK?

@dinhngtu [11:31 xcp-ng-akz ~]# zpool status

errors: No known data errors

I guess so...

@ovicz How is your SR connected to the host, via NFS or something else?

ovicz

@dinhngtu No. It's a local SSD mounted with the zfs pool. Everything worked before the update. I don't see other errors in the host.

dinhngtu

@ovicz Let me call @storage

dinhngtu

@ovicz To confirm, you were using the ZFS integration documented here https://docs.xcp-ng.org/storage/#zfs right?

ovicz

@dinhngtu Yes. Like I said, all was good before the update from testing. The host xcp-ng is on another drive and the zfs pool is on other ssd if that matters. The host is using ext4 partitions.

@ovicz I'd start by listing the VDIs on your SR to see if things are still there.

@ovicz How about xe vdi-list sr-uuid=8e908932-0577-d6f0-3133-14d94a317b90 ?

ovicz

@dinhngtu no ouput from that command.

dinhngtu

@ovicz Ok, I've contacted the storage team for a look.

ronan-a

@ovicz Can you share the /var/log/SMlog file from the master? It's quite strange considering that this driver is small and hasn't been modified.

stormi

@ovicz I'd also like to have a look at /var/log/daemon.log after a failed VM startup attempt.

i have applied updates to my 2 amd home lab hosts. Ryzen 7700x and 7950x amd x670e mobo's. No issues to report. Windows vm migrated between hosts no isssues. No issues with windows vm booting with uefi enabled prior to update.

Strange thing the disks don't appear in xen orchestra but they are on the drive:

@ovicz Hello,

From what I saw in your logs, you have a non QCOW2 sm version, it made the QCOW2 VDIs not available to the storage stack and the XAPI lost them.
If you update again while enabling the QCOW2 repo:

yum update --enablerepo=xcp-ng-testing,xcp-ng-candidates,xcp-ng-qcow2

A SR scan will make the VDI available to the XAPI. Though you will have to identify them and connect them to the VM manually, since this information was lost.

stormi

I added a warning to my initial announcement.
