It's probably a bad design of migration protocol as well.The TPM emulator backend migrates blobs that are only understood by swtpm.The separate slirp-helper net backend does the same too IIUCWhen sys mem pages are marked dirty and content is copied to destination, content of sys mem is also opaque to QEMU.Non-opaque RAM might be a bit too much to expect, though. :) Paolo
