All, Just an FYI... Modifying /etc/libvert/quemu/$VM_GuestName.xml to include the xml snippet from http://hansdegoede.livejournal.com/11084.html the warning message does not appear. [] stop VM_Guest with virt-manger [] service libvertd stop [] vi /etc/libvert/quemu/$VM_GuestName.xml Comment out -or- remove <controller type='usb'> xml entries Add in xml from here, as instructed: http://hansdegoede.livejournal.com/11084.html [] service libvertd start [] start VM_Guest with virt-manager [] view VM_Guest virt-viewer --connect qemu:///system $VM_Guest [] Select File->USB device selection you _are_ able to check the box next to the USB device you inserted without the warning message.

warning-message
(In reply to PaulB from comment #2) > Created attachment 794445 [details] > warning-message Presumably because Hans XML had 4 redir devices. If you have the same number, you should get the same result. The warning + exclamation mark is intended behavior, the info box at the top containing the warning is there to explain why some devices are grayed out / why you cannot select any other devices to redirect. As is seen in the screen-shot the line for the selected device is not grayed out, and unchecking it will clear the warning, and you've noticed the device is redirected and works fine. Closing this as notabug. One possible improvement would be for the warning to read "There are no more free USB channels" rather then "There are no free USB channels", would that be more clear ? Hans, Thank you for the explanation. After reading your comment#4, I understand. I think this should be improved, as it is confusing enough to require an explanation. As it seems to me when you "select the check box" the warning appears, making one feel they have created an issue. Regarding possible improvement: [] Can we have multiple USB channels by default? [] Could we use bullets rather than check boxes, when only one option is permissible?

Yes, and this is what all the howto-s advise one to do. > [] Could we use bullets rather than check boxes, > when only one option is permissible? No. I still consider this not a bug. |
Description of problem: Using a Fedora19 Host with a Windows7 VM_Guest installed. Redirecting a USB device to the Windows7 x64 VM_Guest, we see the following issue: When you start the VM_Win7Guest and select File->USB device selection you _are_ able to check the box next to the USB device you inserted. However, we see a warning (an exclamation point inside a yellow triangle) that states "There are no free USB channels". However, once I click the close button, the USB device is detected and accessible by the VM_Win7Guest. Version-Release number of selected component (if applicable): kernel 3.9.5-301.fc19.x86_64 qemu-kvm.x86_64 2:1.4.2-3.fc19 qemu-kvm-tools.x86_64 2:1.4.2-7.fc19 qemu-guest-agent.x86_64 2:1.4.2-3.fc19 libverto.x86_64 0.2.5-2.fc19 virt-manager.noarch 0.10.0-0.5.gitde1695b2.fc19 virt-viewer.x86_64 0.5.6-1.fc19 How reproducible: Consistently Steps to Reproduce: 1. In virt-manager-> Show virtual hardware details -Display-> type spice -Video-> model QXL -Controller USB-> type USB / model USB2 -Add hardware-> USB redirection-> spice channel 2. virt-viewer --connect qemu:///system $VM_Guest 3. From task bar: File->USB device selection 4. Check the box next to your inserted USB device 5. Warning message appears (see attached image: warning-message) Actual results: I see a warning message that states "There are no free USB channels". However, once I click the close button, the USB device is detected and accessible by the VM_Win7Guest. Expected results: No warning message Additional info: This is a follow up from the following BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1003083
