[Pkg-libvirt-maintainers] Bug#1107536: PPC64LE: Device hotplug/unplug requires guest reboot

[Trupti]

Package: libvirt-daemon
Severity: important
Tags: trixie ppc64el

Version Info:

Host/Guest OS: Debian Trixie/sid (powerpc64le)
Kernel: 6.12.27-powerpc64le-64k
QEMU: 10.0.0
Libvirt: 11.3.0

Issue:

Live-attaching or detaching a device with virsh on a Debian Trixie 
(ppc64le) guest does not take effect immediately. While the host command 
succeeds, the guest OS only recognizes the change after a full reboot. 
This defeats the purpose of the hotplug feature.

Steps to reproduce:
1) Start a guest with Debian-Trixie OS same as Host
2) Attach an interface to guest using below virsh attach-device command
    'virsh attach-interface --live vm bridge --source virbr0'
3) The command executes successfully and give output as "Interface 
attached successfully"
4) But the interface is not immediately attached to guest. When the 
guest is rebooted , then the
    interface is seen on the guest.
5) Same is happening with virsh detach-interface command. A guest reboot 
is required to remove
    the interface from guest

Thanks Trupti
