Role(master or peer) controls how the domain behaves on migration. For more details about migration with ivshmem, see https://git.qemu.org/?p=qemu.git;a=blob_plain;f=docs/system/ivshmem.rst;hb=HEAD It's a optional attribute in libvirt, and qemu will choose default role for ivshmem device if the user is not specified. With device property 'role', the value can be 'master' or 'peer'. - 'master' (means 'master=on' in qemu), the guest will copy the shared memory on migration to the destination host. - 'peer' (means 'master=off' in qemu), the migration is disabled.
