[libvirt-users] hotplug



Another separate thread for a slightly separate issue.

For some reason, hotplugging disks does not work for me.

I built my guest with ubuntu's vmbuilder. It's Precise, virtual.

I have acpiphp in my /etc/modules file:

$ lsmod
Module                  Size  Used by
psmouse                97443  0 
serio_raw              13211  0 
virtio_balloon         13108  0 
acpiphp                24231  0 
floppy                 70365  0

hotplug_pci seems to be compiled into the kernel:

$ grep HOTPLUG_PCI /boot/config-3.2.0-32-virtual 
CONFIG_HOTPLUG_PCI_PCIE=y
CONFIG_HOTPLUG_PCI=y
CONFIG_HOTPLUG_PCI_FAKE=m
CONFIG_HOTPLUG_PCI_ACPI=m
CONFIG_HOTPLUG_PCI_ACPI_IBM=m
CONFIG_HOTPLUG_PCI_CPCI=y
CONFIG_HOTPLUG_PCI_CPCI_ZT5550=m
CONFIG_HOTPLUG_PCI_CPCI_GENERIC=m
CONFIG_HOTPLUG_PCI_SHPC=m

But when I attach a disk, absolutely nothing happens in the guest. No messages in the logs, no change to /proc/partitions, no new device nodes. When I reboot, the disk appears.

Any ideas?

Thanks,

Douglas
