Without this the struct has the wrong size: sizeof() evaluates
to 16 instead of 13. In most cases the bug is hidden by the
fact that guests submits a buffer which is exactly 13 bytes
long, so the padding added by the compiler is simply ignored.
But sometimes guests submit a larger buffer and expe

Hi all,
I have been trying to use the hwprofile and cache plugin on

the plugins worked (eventhough the cache plugin
Some functions of the plugin API were missing in
the symbol list. However, they are all used by
the contributed example plugins. QEMU fails to
load the plugin if the function symbol is not

Haiku's virtio driver (PCI) is looking for PCIID Devices 0x1000-0x103F
I've noticed qemu-6.
