[Bug 1190387] Re: attach-device of usb falsely declares device in use by other domain
This bug was fixed in the package libvirt - 0.9.8-2ubuntu17.15 --- libvirt (0.9.8-2ubuntu17.15) precise-proposed; urgency=low * update fix-for-parallel-port-passthrough-for-qemu: the xml for the new testcase was too modern and caused the test to fail by including new keywords. libvirt (0.9.8-2ubuntu17.14) precise-proposed; urgency=low * qemu-delete-usb-devices-on-stop and qemu-build-activeusbhostdevs-on-reconnect: ensure that we can re-use a usb device after another domain using the device has shut down. (LP: #1190387) Backported from upstream git. * cherrypick fix-for-parallel-port-passthrough-for-qemu from upstream (LP: #1203620) -- Serge HallynMon, 14 Oct 2013 10:32:22 -0500 ** Changed in: libvirt (Ubuntu Precise) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1190387 Title: attach-device of usb falsely declares device in use by other domain To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1190387/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
