[PATCH] hw/riscv: virt: Avoid double FDT platform node

``` The call from `create_fdt_imsic` is not needed as an imsic is currently always combined with an aplic that will create the nodes. Fixes: 3029fab64309 ("hw/riscv: virt: Add support for generating platform FDT entries") Signed-off-by: Dylan Reid --- hw/riscv/virt.c | 5 - 1 file

[PATCH] vhost-user: Check vhost features for CONFIGURE_MEM_SLOTS

The `CONFIGURE_MEM_SLOTS` feature is specified by vhost, not by virtio. Check the vhost flags for it being set. I noticed this while testing a new vhost implementation that doesn't yet support configuring memory slots and retested with dpdk's block example as well. Signed-off-by:
