Hi,
during IOMMU API function testing on s390 I hit the following scenario:
After binding a device to vfio-pci, the user completes the VFIO_SET_IOMMU
ioctl and stops, see the sample C program below. Now the device is manually
removed via echo 1 /sys/bus/pci/devices/.../remove, which completes
When a user completes the VFIO_SET_IOMMU ioctl and the vfio-pci device is
removed thereafter (before any other ioctl like VFIO_GROUP_GET_DEVICE_FD),
then the detach_dev callback of the underlying IOMMU API is never called.
This patch adds a call to vfio_group_try_dissolve_container() to the

To detach tap device automatically from bridge when exiting,
just like what the reverse of script does.

Changelog:
v2:
- Rebase with Will kvmtool.git tree[1]
- Drop patch2 from v1, as commit f83dc816a9c7 has already fix it
v3:
- Remove -Wunused-variable warnings
Fan Du (2):
kvmtool: Introduce downscript option for virtio-net
kvmtool: Restrict virtio queue number to 1 when vhost on
vhost kernel driver does not support mutiple queue yet,
Tweak queue number will fail with --net mode=tap,vhost=1,mq=2
as below when lkvm trying to set ring kick fd for queue 2:
VHOST_SET_VRING_KICK failed: No buffer space available
Error on this scenario, and overide with the default one queue
Hi Will,
thanks for applying the fixes.
Here are the remaining patches which we talked about.
I changed the PAGE_SIZE definition according to Szabolcs' comments
(thanks for that!) and just added the -Wno-format-nonliteral option
unconditionally to our list of warning options to appease clang.
PAGE_SIZE may have been defined by the C libary (musl-libc does that).
So avoid redefining it here unconditionally, instead only use our
definition if none has been provided by the libc.

The clang compiler by default dislikes non-literal format strings
in *printf functions, so it complains about kvm__set_dir() in kvm.c
and about the error reporting functions.
Since a fix is not easy and the code itself is fine (just seems that
the compiler is not smart enough to see that), let's

Hi,
thanks for the rework, that looks good to me, some minor nits below.
Not sure if that requires a new version, maybe Will can fix that up when
he applies it.
