XCP-ng 8.3 updates announcements and testing

Pilow

@manilx yup, same here
we evacuate & roll patch manually because RPU is inconsistent in achieving a full pool update nowadays

maximum hosts in pools are 3, so it is still easy to process manually
thoses with 5-6+ hosts must be more painful

That would be interesting to group your findings/issues on RPU in a dedicated topic, because I don't think the logic changed recently So it's an interesting investigation to make.

Seems to be working well on my test systems as well.

update to latest test patches on 2nd pool. no issue. LACP worked, started UB26 VM on host 4 and live migrated to host 3.

@rzr Installed those security update candidates in my XCP-ng test environment.
So far no issues whatsoever. Basic operations all work. VMs running etc.

New security update candidates for XCP-ng 8.3 LTS (kernel)

Test window before official release of the updates

~3 days

The testing window is extended a bit, expect also a next batch (to be tested later this month).

It has been planned to group updates for the convenience of administrators (stay tuned in blog).

Meanwhile If you didn't notice yet, an updated xen package landed in testing repo, it addresses some low risk vulnerabilities as reported at:

VSA-2026-017 (XSA-491, CVE-2026-42487)
VSA-2026-018 (XSA-492, CVE-2026-42489 - CVE-2026-42490),
VSA-2026-019 (CVE-2025-10263, XSA-493)
VSA-2026-020 (CVE-2026-42488, XSA-494)

More to come soon

@rzr

I also installed updates this morning no new issues to report.

@rzr Updates installed everywhere (on top of the previous updates). Rolling pool reboot worked this time (with correct prep).
