New Contents: Previously, more than 30 cycles network card hot-plug and hot-unplug caused the guest to reject any further hotplug. With this update, the RHELSCSI driver can sustain repeated cycles of network card hot-plug and hot-unplug. Version-Release number of selected component: xen-3.0.3-117.el5 kernel-xen-2.6.18-228.el5 xenpv-win: 1.2.0 guest: Windows2008r2 HVM Detailed steps: 1. Edit the vm's config file to install xenpv-win, change the disk specification like disk=['file:...', 'file:/usr/share/xenpv-win/xenpv-win.iso,hdc:cdrom,r', 'file:/usr/share/xenpv-win/xenpv-win-debug.iso,hdd:cdrom,r'] 2. Start the vm with xm create command: [host]# xm create $vm-config 3. Open "My Computer", double click "xenpv-win-1.2.0(D:)(CDROM Drive)" Or Open CD Drive, then double click xenpv-win.exe Then the installer start the installation process, choose "next" all the way. 4. Execute hot-plug and hot-unplug 500 times. [host]# xm pci-attach $domU $dev [host]# xm pci-detach $domU $dev 5. using vncviewer to login the guest vm and check. Detailed result: 1. The guest works well and blue-screen doesn't occur. I cannot reproduce this bug, so change it to verified. An advisory has been issued which should help the problem described in this bug report.
