Version-Release number of selected component (if applicable):
virt-manager -0.6.1-7.el5
xen-3.0.3-90.el5
libvirt-0.6.3-15.el5

host:RHEL5 Server x86_64,RHEL5 Client x86_64,RHEL5 Server i386,RHEL5 Client
i386,RHEL5 IA64


How reproducible:
100%

5'.shutdown then view the hardware list 
5".reboot to verify the virtual is added succussfully,then shutdown view the hardware list
6.run again the vm

  
Actual results:
1.after 5',the virtual disk just added not display on hardware list
2.after 5",the virtual disk just added not display on hardware list
3.after 6,the virtual disk just added not display on hardware list


Expected results:
1.after 5',the virtual disk just added display on hardware list

Hmm. This is due to how libvirt/xen handle hotplugging, and how virt-manager exposes it to the user. virt-manager should ensure that any hotplug operation is persistent across VM start/shutdown.

This is fixed in upstream virt-manager, but it might be a pretty invasive/substancial backport. I'll have to look at possibly minimizing the risk.
