+1 to this, also ran into this in our lab testing. Thanks for sharing this information! Regards, Bailey

Thanks a lot for the heads up, Dan!
Zitat von Dan van der Ster <dan.vanderster@clyso.com>:
Hey all,
The upcoming community Ceph container images will be based on CentOS
In our Clyso CI testing lab we learned that el9-based images won't run on some (default) qemu VMs. Where our el8-based images run well, our new el9-based images get:
error during bootstrap: Fatal glibc error: CPU does not support x86-64-v2
This is because RHEL 9 (and clones) added a hard requirement on x86-64-
v2:
* https://srobb.net/rhel9.html * https://forums.rockylinux.org/t/el9-will-require-x86-64-v2-support/531 1 * https://developers.redhat.com/blog/2021/01/05/building-red-hat-enterpr ise-linux-9-for-the-x86-64-v2-microarchitecture-level * https://access.redhat.com/solutions/6833751
The reason for the failure in our testing is that some of our virtual nodes use qemu's default CPU emulation (qemu64), which does not support x86-64-v2. The solution for these nodes is to switch to "host" or something else listed at https://www.qemu.org/docs/master/system/i386/cpu.html
I would encourage cephadm/Rook users with daemons on VM hosts to verify their CPU modes on their VMs prior to any upgrades, and make the necessary changes to the hypervisor configuration ahead of time.
Best, Dan
