This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. This bug also exists when using other guest(both Linux and Windows) And guest could not identify the added device. check pci device cmd: linux)# lspci windows)# systeminfo Does it happen when you're using QMP too? Please use device_add. pci_add is the older way of doing it, it should be removed from the RHEL6 code. *** Bug 589859 has been marked as a duplicate of this bug. *** Verified on qemu-kvm-0.12.1.2-2.73.el6, passed.

Original fix had an issue and an additional fix was submitted. Reopening. *** Bug 607621 has been marked as a duplicate of this bug. *** Close the bug according to Comment 10. Event posted on 07-27-2010 12:54pm EDT by Glen Johnson ------- Comment From anantyog.com 2010-07-27 12:44 EDT------- This problem is reproducible with 'device_add' and without using vlans too, Step followed to recreate the issue 1)started the guest with net "user" interface /usr/libexec/qemu-kvm -drive file=/root/sdb/images/win7-32.qcow2 -smp 2 -m 6144 --monitor stdio -net nic,model=virtio,netdev=kuser1 -netdev user,id=kuser1 -vnc :10 2)Hotpluged a "rtl8139" card using the commands below (qemu) netdev_add tap,id=tap1,script=br (qemu) device_add rtl8139,netdev=tap1 Hotpluged "rtl8139" was not able to get ip from the dhcp server 3)Hotpluged a "e1000" card using the commands below (qemu) netdev_add tap,id=tap2,script=br (qemu) device_add e1000,netdev=tap2 which results in error "device cannot start(code 10) in windows device manager. I tried hotpluging using virsh, using both "default" network and bridge interface. command used to hotplug the network device was :"attach-device win7 attach1.xml" steps and xml files used are below 1)default network <interface type='network'> <source network='default'/> <mac address='52:54:00:72:51:2e'/> <model type='virtio'/> </interface> 2)bridge network <interface type='bridge'> <source bridge='kvmbr0'/> <model type='e1000'/> </interface> The error still occurred with virsh, there was no change in results. Only hotplugging of "virtio" nic seems to work.

The bug still occurs. Internal Status set to 'Waiting on Support' Status set to: Waiting on Tech This event sent from IssueTracker by jkachuck issue 910133 What's the qemu version that you use? A new BZ 607611 is soon to be build and probably solve it. I just checked that the fix for bug 607611 does fix this issue. This issue was separate for the one that this bug was opened for, which was hot-plugging of a particular nic card got a different nic card hotplugged. So I'll close this bug as 'worksforme' and you can use bug 607611 to track the problem of hotplugged nic not working in guests.
