[PATCH 0/2] qemu: monitor: Fix handling of 'detach' for 'migrate' and 'dump-guest-memory' QMP commands
by Peter Krempa 21 May '25

21 May '25

QEMU is deprecating 'detach' argument of 'migrate' as it was never actually used. Drop it in libvirt as we always specify it. The monitor handler of 'dump-guest-memory' allows controlling 'detach' but always passes true. Libvirt doesn't want to block the monitor so hardcode 'true' in the monitor code instead.

libvirt TLS certificates letsencrypt
by Jani Heikkinen 20 May '25

20 May '25

Hello! I am part of infrastructure team at BFH and we are building an openstack installation. A couple of months ago I was experimenting with setting up noVNC consoles with encryption. Connecting until the novncproxy service with TLS can be done with no issues, but the connection between libvirt and the proxy turned out to be problematic. We would really love to use letsencrypt certificates which are generated for each server/container, instead of relying on creating own CA and generate certificates. With libvirt, using letsencrypt is impossible, since the code does bunch of checks for properties of the TLS certificates, see: https://github.com/libvirt/libvirt/blob/bf79a021a6437b4f85469a53f650bff62db… Does anybody know, why these checks exist? They de facto prevent using anything else than self-generated certificates for securing vnc console traffic. Is using my own self-created CA somehow more trustworthy than LetsEncrypt root CA?

[PATCH v1 0/2] Disable Deprecated Features by Default on s390 CPU Models
by Collin Walling 19 May '25

19 May '25

The intention of reporting deprecated features and modifying the guest CPU model was to alleviate the user from the burden of preparing a guest with the necessary amendments to assure migration to newer hardware. While that goal was met by way of the "deprecated_features='on|off'" attribute, it still adds an extra step that the user must be aware to prepare a guest for migration and the errors that stem from an unsuccessful migration (due to feature incompatibility) is not always clear how to resolve. These patches make s390 CPU host models migration ready from the get-go by disabling deprecated features by default. They may still be disabled for other model types via the respective attribute, or reenabled if desired.
