From 03d339dc03dbf63dbe73f7e8197508ed80617cc2 Mon Sep 17 00:00:00 2001 From: Akash Kulhalli via Devel Date: Wed, 29 Apr 2026 17:43:26 +0530 Subject: [PATCH] qemu: emit vcpu-removed event on unplug completion Emit the vcpu-removed event when QEMU vCPU unplug completes. Hook this into qemuDomainRemoveVcpu(), which covers both the synchronous completion path and the DEVICE_DELETED-driven alias removal path. Some architectures may have multiple vcpus grouped under a single qemu vcpu object; on those platforms a `vcpu-removed` event will be emitted for each vcpu that is removed from this group.
