Ich versuche, eine VM in QEMU zu migrieren. Nachdem ich den Speicher per Hotplug in meine VM eingebunden habe, kann ich sie nicht migrieren und habe das Problem, dass Unknown ramblock "mem1", cannot accept migrationdieser Name in Ordnung ist und sie in der Migrationsquelle tatsächlich existiert. Die Parameter für die Quelle und das Ziel sind:

Ich habe 1 CPU und 2 GB RAM per Hotplug angeschlossen. Es funktioniert unter Qemu 5.0.0 und Ubuntu 20.04. Ich habe dieses Problem unter QEMU 2.11.1 unter Ubuntu 18.04 und ich habe Probleme beim Upgrade.

Ich denke, das könnte ein alter Fehler gewesen sein, der durch das Upstream-Commit fa0cb34d2210cc749b9a70db99bb41c56ad20831 behoben wurde, bei dem einige Speicherobjekte /Objekt/Name statt nur „Name“ genannt wurden.
