Description of problem: ------------------------- When there is "pci-assign" device and "-incoming" in cmd, qemu-kvm fails to start, it should be the same when there is "usb-host" device. Version-Release number of selected component (if applicable): -------------------------------------------------------------- qemu-kvm-0.12.1.2-2.231.el6.x86_64 How reproducible: ----------------- 100% Steps to Reproduce: ------------------- 1.boot guest with "-device usb-host,hostbus=X,hostaddr=X,id=X -incoming tcp:0:5555" where the usb-host device does exist. Actual results: ----------------- Qemu-kvm starts successfully and begins to listen. Expected results: ------------------ Qemu-kvm should refuse to start and prompt error.
FYI: https://bugzilla.redhat.com/show_bug.cgi?id=723870 #1: we should fail migration if usb devices tagged without migration support #15: fail migration with usb device passthru'd Fail migration instead of refusing launch listening mode works as designed, I think.
also notice that usb is different from pci passthrough. usb understands hot-plug/unplug natively. In pci, that is much, much more complicated. For comment 3, I guess that we can close this bugzilla?

Since current solution works well, no need to be consistent with pci passthrough way, close this as WONTFIX.
