Version-Release number of selected component (if applicable):
kvm-83-207.el5


How reproducible:
100%


Steps to Reproduce:
1. boot guest with
/usr/libexec/qemu-kvm -name 'vm1' \
-monitor stdio \
-serial unix:'/tmp/serial-20101109-190908-JE7f',server,nowait \
-drive file='/home/images/win7-32-virtio.qcow2',index=0,if=virtio,media=disk,cache=none,boot=on,format=qcow2 \
-net nic,vlan=0,model=virtio,macaddr='02:30:1F:8D:b2:99' \
-net tap,vlan=0,ifname='virtio_0_8000',script='/home/images/qemu-ifup-switch',downscript='no' \
-m 4096 -smp 2 \
-drive file='/home/images/winutils.iso',media=cdrom,index=1 \
-cpu qemu64,+x2apic \
-soundhw ac97 \
-redir tcp:5000::10023 \
-vnc :0 \
-spice port=8000,disable-ticketing -qxl 1 \
-rtc-td-hack \
-M rhel5.5.0 -usbdevice tablet

2. hot add a nic by,
(qemu) pci_add pci_addr=auto nic model=rtl8139

3. wait for guest to install the driver for the newly added nic

  
Actual results:
qemu-kvm aborted.


Expected results:
the nic is added to the guest successfully, at least the guest
does not crash.

Additional info:
1.
if restart the guest after crash, and do pci_add again, guest won't abort,
but the nic does not show in guest.

2.
work good when adding a virtio nic

3.

Please test with the kvm rpm in this brew build and report the results:

tested good. nic devices hot added can all be recognized.
Comment 9 Cao, Chen 2010-11-23 03:20:46 UTC 
Verified.

the nic can be hot-added successfully, both with rtl8139 and virtio model.

# rpm -q kvm
kvm-83-208.el5

# uname -r
2.6.18-232.el5


but the newly added rtl8139 nic cannot get ip address, it should be another
problem.
