The bug can not be reproduce on rhel7.0 release version(virt-manager-0.10.0-20.el7). it seems that libvirt doesn't have an event for this, and virt-manager passed from polling libvirt status to be event-driven. I will investigate this better to be sure about it. commit be7611b645e2e888a0decc4c02f411a967ccee80

connection: refresh domain XML on device hotplug
Listen to the VIR_DOMAIN_EVENT_ID_DEVICE_ADDED event
too, added by libvirt 1.2.15.

I can reproduce this bug with following product versions:
virt-manager-1.1.0-12.el7.noarch
libvirt-1.2.8-11.el7.x86_64
libvirt-python-1.2.8-1.el7.x86_64
Steps are the same as description.
Then verify with the latest versions:
virt-manager-1.2.0-4.el7.noarch
libvirt-1.2.15-2.el7.x86_64
libvirt-python-1.2.15-1.el7.x86_64
Steps:
1. Prepare a running guest, works well, check the network device in guest and virt-manager
# virsh list
Id Name State
----------------------------------------------------
3 rhel6.7 running
2. Dumpxml guest for interface list, also checks it in guest
# virsh dumpxml rhel6.7
...
<interface type='network'>
<mac address='52:54:00:b7:29:90'/>
<source network='default'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
...
# virsh domiflist rhel6.7
Interface Type Source Model MAC
-------------------------------------------------------
vnet0 network default virtio 52:54:00:b7:29:90
in guest:
# lspci |grep Eth
00:03.0 Ethernet controller: Red Hat, Inc Virtio network device
2. Prepare a network xml, attach it to the guest
# cat /tmp/network1.xml
<interface type='network'>
<mac address='52:54:00:b0:8d:2c'/>
<source network='default' bridge='virbr0'/>
<target dev='vnet0'/>
<model type='rtl8139'/>
</interface>
# virsh attach-device rhel6.7 /tmp/network1.xml
Device attached successfully
3. Recheck the guest interface list and dumpxml to confirm the network device has been hot-plugged to guest success
# virsh domiflist rhel6.7
Interface Type Source Model MAC
-------------------------------------------------------
vnet0 network default virtio 52:54:00:b7:29:90
vnet1 network default rtl8139 52:54:00:b0:8d:2c
# virsh dumpxml rhel6.7
...
<interface type='network'>
<mac address='52:54:00:b7:29:90'/>
<source network='default'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
<interface type='network'>
<mac address='52:54:00:b0:8d:2c'/>
<source network='default' bridge='virbr0'/>
<target dev='vnet1'/>
<model type='rtl8139'/>
<alias name='net1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>
...
4. In guest, network exist
# lspci |grep Eth
00:03.0 Ethernet controller: Red Hat, Inc Virtio network device
00:09.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (rev 20) ----> This is the new added hot-plug network device
5. Check with virt-manager for the new added hot-plug network interface device, click "Show virtual hardware details" menu.
Result:
After Step 5, virt-manager can sync with virsh command immediately for hot-plug device attach.
According to the result above in the latest version, move this bug from ON_QA to VERIFIED.

Close virt-manger window and open it again, or restart libvirtd, the new added hot-plug devices can be seen from virt-manger. Additional info: The same issue also hit on hot-plug for disk, console, usb hostdev devices. Actual result: Although, virsh command has attached device successfully, but virt-manager does not sync with guest new added hot-plug devices immediately. It is abnormal. Expected result: Virt-manage can sync with virsh command immediately for hot-plug device attach.
