The 1st patch add attribute 'role', it based on Martin's old patch https://www.redhat.com/archives/libvir-list/2016-September/msg00536.html The 2nd patch remove shmem name check in migraiton, which allows user change shared memory path on destination host. v3 -> v2: 1. Correct description of shmem ��ole�?attribute. If there is any mistake in the description, please show me. Sorry for my poor English :) 2. Remove the inappropriate suggestion in migration log. 3. allow shmem name change in migration, instead add a new 'mem-path' attribute. v2 -> v1: Fix ivshmem testcases failure.
