[libvirt-users] virsh attach-device : Bus 'pci.0' does not support hotplugging.
Hi , Trying to attach a disk to existing VM using virsh attach-device - XML <disk type='file' device='disk'> <driver name='qemu' type='qcow2' cache='none' io='native'/> <source file='/var/lib/libvirt/images/guest.qcow2'/> <target dev='vdc' bus='virtio'/> </disk> After executing the command I am getting - [root@cent7 ~]# virsh attach-device lib-virt-man-001 newDisk.xml error: Failed to attach device from newDisk.xml error: internal error: unable to execute QEMU command 'device_add': Bus 'pci.0' does not support hotplugging. [root@cent7 ~]# virsh version Compiled against library: libvirt 1.2.17 Using library: libvirt 1.2.17 Using API: QEMU 1.2.17 Running hypervisor: QEMU 1.5.3 While searching on this issue found that some have suggested to install following - modprobe acpiphp modprobe pci_hotplug I am not sure if this is QEMU issue or libvirt issue. Any help in this would be appreciated. Thanks, Keyur Bhalerao
