Re: [Qemu-devel] Re: [libvirt] dynamic scsi disk attach seems to be broken in qemu(-kvm)-0.11, libvirt-0.7.1




I would like some advice on how to proceed with this bug, and where
the solution lies...in qemu or in libvirt.  Ultimately, I would like
the behavior we had in our previous release with kvm-84 and
libvirt-0.6.1, where we could dynamically add scsi devices without a
problem, using:
  pci_add 1 storage file=/tmp/foo,if=scsi

Can anyone else reproduce this?  Is this considered a regression by
anyone else?  Where should I look to solve this, in libvirt, or in
qemu?

Independently of what I said about libvirt not implementing SCSI hotplug
with the right apporoach, the pci-add stuff should definitely work, so if it doesn't then this is a regression that needs to be fixed

There's definitely a bug somewhere. When you add a second PCI controller, the controller shows up in the guest but the disk attached to the controller isn't visible. Rescanning the scsi bus does not make the disk appear either.
