CentOS Sream 9 pre-release chroots added to Fedora Copr

[Pavel Raiskup]

Hi all,

just for the info, we enabled the `centos-stream-9-x86_64` and
`centos-stream-9-aarch64` chroots in Fedora Copr.  Note that we build
directly from composes [1] without mirrors (some failures can expected),
and that the packages are not GPG-signed.  You have been warned :-)

The ppc64le doesn't seem to build on Power8 hardware we have [2], and
s390x has some troubles with qemu emulation [3].  So those architectures
are at least for now disabled.

[2] https://bugzilla.redhat.com/show_bug.cgi?id=1985364
[3] Fatal glibc error: CPU lacks VXE support (z14 or later required),

Happy building!
Pavel

CentOS Stream 9 and RHEL-9 will only support Power 9 and above
architectures. So COPR will not be able to build CS9 or RHEL-9 at this
time.

I am guessing the s390x emulation is also an architectural issue as I
believe the minimal system for 9 to work on has also moved.

This one is:

https://bugzilla.redhat.com/show_bug.cgi?id=1967905

Seems like it should be fixed with a sufficiently recent copy of qemu.
(Hmm, you're running copr / s390x on top of software emulation ...?)

Rich.

I'm trying to find out from the s390x QEMU maintainers about the
likely fix requird to make this work.

Can you tell me what QEMU version is in use in this environment.

Regards,
Daniel

It will be fixed in QEMU 6.1.0 which is coming out in a month-ish:

https://wiki.qemu.org/Planning/6.1

and will be addressed by this patch series

https://lore.kernel.org/qemu-devel/[e-mail]/

This futur QEMU release will go into f35 rawhide, and virt-preview repo
can be used if you will need it for f34

Regards,
Daniel

Nice, thank you for the reference!

I'm curious...  couldn't we run CentOS Stream 9 ppc64le builds through qemu
emulation as well?

Quite possibly.
