向虚拟机热插一块 Watchdog 卡不再失败
在以前的版本中，如果没有 PCI 插槽可用，向正在运行的虚拟机(VM)添加一块 Watchdog 卡会失败，并显示以下错误：
Failed to configure watchdog ERROR Error attempting device hotplug: internal error: No more available PCI slots
Failed to configure watchdog
ERROR Error attempting device hotplug: internal error: No more available PCI slots有了此更新，这个问题已被解决，向正在运行的虚拟机中添加一块 Watchdog 卡现在可以按预期正常工作。
