From 586b0ed81828a443717b018989f2bced1bcfac01 Mon Sep 17 00:00:00 2001 From: Cole Robinson Date: Thu, 5 Dec 2013 14:59:05 -0500 Subject: [PATCH] qemu: hotplug: Fix adding USB devices to the driver list We were unconditionally removing the device from the host list, when it should only be done on error. This fixes USB collision detection when hotplugging the same device to two guests. --- src/qemu/qemu_hotplug.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/qemu/qemu_hotplug.c b/src/qemu/qemu_hotplug.c index b7512a71dc..16b990d9cc 100644 --- a/src/qemu/qemu_hotplug.c +++ b/src/qemu/qemu_hotplug.c @@ -1515,9 +1515,9 @@ cleanup: virSecurityManagerRestoreHostdevLabel(driver->securityManager, vm->def, hostdev, NULL) < 0) VIR_WARN("Unable to restore host device labelling on hotplug fail"); + if (added) + virUSBDeviceListSteal(driver->activeUsbHostdevs, usb); } - if (added) - virUSBDeviceListSteal(driver->activeUsbHostdevs, usb); if (list && usb && !virUSBDeviceListFind(list, usb) && !virUSBDeviceListFind(driver->activeUsbHostdevs, usb)) -- GitLab
