This commit adds support for the vhost-user interface to the passt
network backend, enabling high-performance, accelerated networking for
guests using passt.
The passt backend can now operate in a vhost-user mode, where it
communicates with the guest's virtio-net device over

This commit introduces support for passt as a new network backend.
passt is an unprivileged, user-mode networking solution that provides
connectivity for virtual machines by launching an external helper process.
The implementation reuses the generic stream data handling logi

Previously, the vhost_net_get_feature_bits() function in
hw/net/vhost_net.c used a large switch statement to determine
the appropriate feature bits based on the NetClientDriver type.
This created unnecessary coupling between the generic vhost layer

(This is just the POC code to use in-place conversion gmem.)
Try to use in-place conversion gmem when it is supported.
When in-place conversion is enabled, there is no need to discard memory
since it still needs to be used as the memory of opposite attribute
after conversion.
Fo
Currently, the TDVF cannot work with gmem in-place conversion because
current implementation of KVM_TDX_INIT_MEM_REGION in KVM requires
gmem of TDVF to be valid for both shared and private at the same time.
To workaround it, explicitly not enable in-place conversion for internal

Hi all,
This is the POC to enable in-place conversion and hugetlb support of
gmem (guest memfd) in QEMU. It can work with 1G gmem support series[1] and
TDX hugepage support series[2] to run TDX guest with hugepage. I don't
have SNP environment and don't know how it goes with SNP.
It is just the P

Try with hugetlb first when hugetlb is supported by gmem. If hugetlb

The hugetlb size is hardcoded as GUESTMEM_HUGETLB_FLAG_2MB. I'm not sur
