[Qemu-devel] scp during migration with vhost fails

[Jason Wang]

Hello all:

During testing, I find doing scp during migration with vhost fails with 
warnings in guest like:

Corrupted MAC on input.
Disconnecting: Packet corrupt.
lost connection

Here's the bisect result:

Commit a01672d3968cf91208666d371784110bfde9d4f8 kvm: convert to MemoryListener 
API is the last commit that works well.

With commit 04097f7c5957273c578f72b9bd603ba6b1d69e33 vhost: convert to 
MemoryListener API, guest network is unusable with warning of "bad gso type"

With commit d743c382861eaa1e13f503b05aba5a382a7e7f7c vhost: fix incorrect 
userspace address, guest network is available, but scp during migration may 
fail.

Looks like the issue is related to memory api, any thoughts?

Thanks
