Hi Michal, I found this problem while performing migration, based on libvirt version: 6.2.0 SELinux mode: permissive
Steps: 1. start a vm configured with pipe-type serial port. <serial type='pipe'> <source path='/tmp/test_pipe'/> <target type='system-serial' port='1'> <model name='pl011'/> </target> </serial> 2. migrate vm to Dst-side where no '/tmp/test_pipe' exits. 3. migration failed in Dst-side qemuProcessLaunch, and the path's label that has been set is not restored ('/var/lib/libvirt/qemu/nvram/XXX.fd').
I have no idea why 2)rollback you mentioned didn't work.
I'm not sure. I could not reproduce with the current master. Is it possible for you to try the master? Michal
