7 months ago I'm not set up to try this at the moment - but perhaps it's another problem related to delaying setup of the interface in the container's network namespace from the OCI 'prestart' hook, until after the container task has been started.
(See issue https://github.com/moby/moby/issues/47619, PR https://github.com/moby/moby/pull/47621.)

# If enabled, the runtime will attempt to determine appropriate sandbox size (memory, CPU) before booting the virtual machine. In
# this case, the runtime will not dynamically update the amount of memory and CPU in the virtual machine. This is generally helpful
# when a hardware architecture or hypervisor solutions is utilized which does not support CPU and/or memory hotplug.
# Compatibility for determining appropriate sandbox (VM) size:
# - When running with pods, sandbox sizing information will only be available if using Kubernetes >= 1.23 and containerd >= 1.6. CRI-O
# does not yet support sandbox sizing annotations.
# - When running single containers using a tool like ctr, container sizing information will be available.
static_sandbox_resource_mgmt=false
# If specified, sandbox_bind_mounts identifieds host paths to be mounted (ro) into the sandboxes shared path.
# This is only valid if filesystem sharing is utilized. The provided path(s) will be bindmounted into the shared fs directory.
# If defaults are utilized, these mounts should be available in the guest at `/run/kata-containers/shared/containers/sandbox-mounts`
# These will not be exposed to the container workloads, and are only provided for potential guest services.

# VFIO Mode
# Determines how VFIO devices should be be presented to the container.
# Options:
#
# - vfio
# Matches behaviour of OCI runtimes (e.g. runc) as much as
# possible. VFIO devices will appear in the container as VFIO
# character devices under /dev/vfio. The exact names may differ
# from the host (they need to match the VM's IOMMU group numbers
# rather than the host's)
#
# - guest-kernel
# This is a Kata-specific behaviour that's useful in certain cases.
# The VFIO device is managed by whatever driver in the VM kernel
# claims it. This means it will appear as one or more device nodes
# or network interfaces depending on the nature of the device.
# Using this mode requires specially built workloads that know how
# to locate the relevant device interfaces within the VM.
#
vfio_mode="guest-kernel"
# If enabled, the runtime will not create Kubernetes emptyDir mounts on the guest filesystem. Instead, emptyDir mounts will
# be created on the host and shared via virtio-fs. This is potentially slower, but allows sharing of files from host to guest.

# Applies only if service_offload is true.
# Keys can be provisioned locally (e.g. through a special command or
# a local file) or remotely (usually after the guest is remotely attested).
# The provision setting is a complete URL that lets the Kata agent decide
# which method to use in order to fetch the keys.
#
# Keys can be stored in a local file, in a measured and attested initrd:
#provision=data:///local/key/file
#
# Keys could be fetched through a special command or binary from the
# initrd (guest) image, e.g. a firmware call:
#provision=file:///path/to/bin/fetcher/in/guest
#
# Keys can be remotely provisioned. The Kata agent fetches them from e.g.
# a HTTPS URL:
#provision=https://my-key-broker.foo/tenant/
