I'm on an Xubuntu 16.10 system running the latest version of QEMU-KVM (1.2.6.1). I have a VM running Windows 10, which is launched from virt-manager. Question #1: With the OS not running, from the Hardware Details page I have used "Add Hardware" to attach a USB flash drive. In the hardware list it shows up as "USB 058f:6387" and the details show "Device: 002:003 Alcor Micro Corp. Flash Drive". Nevertheless, when I launch the Windows 10 OS, File Explorer does not see this device. I've also looked in Device Manager and can see no reference to the flash drive. Any clue as to the nature of the problem and what must be done to make this visible to the Windows OS? I am doing this with a flash drive as a test in order to get device attachment working. Ultimately, I will be attaching a usb dongle key to the port which must be seen by a program running in this environment. Question #2: There was no problem adding the Alcor flash drive and it is the only device I have added manually, but when I attempt to add another flash drive or my attached phone, virt-manager reports: "Error adding device: internal error: No free USB ports" Error details: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/addhardware.py", line 1343, in _add_device self.vm.add_device(self._dev) File "/usr/share/virt-manager/virtManager/domain.py", line 568, in add_device self._redefine_xmlobj(xmlobj) File "/usr/share/virt-manager/virtManager/libvirtobject.py", line 389, in _redefine_xmlobj self._define(newxml) File "/usr/share/virt-manager/virtManager/domain.py", line 1094, in _define self.conn.define_domain(newxml) File "/usr/share/virt-manager/virtManager/connection.py", line 677, in define_domain return self._backend.defineXML(xml) File "/usr/lib/python2.7/dist-packages/libvirt.py", line 3800, in defineXML if ret is None:raise libvirtError('virDomainDefineXML() failed', conn=self) libvirtError: internal error: No free USB ports Having support for only one external USB port is surprising. Can you point me to any documentation that indicates how to address this problem and add additional ports? Thanks for you assistance.
