Re: [libvirt] [PATCH] qemu: Do not free the device from activePciHostdevs if it's in use

* src/qemu/qemu_hostdev.c (qemuDomainReAttachHostdevDevices): pciDeviceListFree(pcidevs) at the end free()s the device even if it's in use by other domain, this is complete wrong, and will cause race. E.g. # sh test1.sh Device pci_0000_00_19_0 dettached Domain test started Device attached successfully error: Failed to start domain test2 error: Requested operation is not valid: PCI device 0000:00:19.0 is in use by domain test [ -- 1th time --] Device pci_0000_00_19_0 re-attached [ -- 2th time --] Device pci_0000_00_19_0 re-attached [ -- 3th time --] Device pci_0000_00_19_0 re-attached [ -- 4th time --] Device pci_0000_00_19_0 re-attached [ -- 5th time --] Device pci_0000_00_19_0 re-attached clean up Domain test destroyed Device pci_0000_00_19_0 re-attached
