Setting pci=nomsi seems to do the trick for now. Probably not optimal but it's just a VM and I didn't notice any performance issues.

They appear now. I will try to identify them manually. Thanks for the tip.

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

@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.

@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.

I guess so...

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

@stormi on some yes on some no...I did enabled on one but no go.
They used to work before the update, no matter if secure boot was enabled or not.
