I took a look at the eventfd_chr array in the IVShmemState,
and I noticed that it's allocated with malloc at some point for receiving interrupts
with g_malloc0 in pci_ivshmem_init, but it's never freed in pci_ivshmem_uninit.

Is there such a change somewhere in the patchset I have missed?

Have you checked that the resources allocated during pci_ivshmem_init are released on pci_ivshmem_uninit?

Ciao

Claudio
