Yes that is normal functionality. If you want to add a device with persistence you must have the Virtual Machines turned off. AND you can only have one VM running at a time. The Qubes Team did make a reference to this here. https://www.qubes-os.org/doc/assigning-devices/ "While PCI device can only be used by one powered on VM at a time, it is possible to assign the same device to more than one VM at a time. This means that you can use the device in one VM, shut that VM down, start up a different VM (to which the same device is also assigned), then use the device in that VM. This can be useful if, for example, you have only one USB controller, but you have multiple security domains which all require the use of different USB devices." As well, if you attach a usb device to multiple VMs, you are drawing an attack vector line from one to the next. USB devices, are inherently not trusted. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
