If disable nic in guest's "Network Connections" panel, nic could not be hot-removed through qemu monitor.
1) if disable nic in guest
(qemu) devel_del id1 (nic still in "Network Connections". if enable nic, nic can work)
(qemu) devel_del id1
(qemu) devel_del id1
2) if enable nic in guest
(qemu) devel_del id1 (nic will be removed, disappear from "Network Connections")
(qemu) devel_del id1
Device 'id1' not found
Could not reproduced this problem with all linux guests & other Windows guests
Problem exists with virtio-nic/e1000/rtl8139, it seems the problem of pci-hotplug in piix4.
Could not reproduce this problem with Vmware + win2012 guest.

Triaging old bug tickets... can you still reproduce this issue with the latest version of QEMU? Or could we close this ticket nowadays?
[Expired for QEMU because there has been no activity for 60 days.]
