[PATCH 0/3] migration: add qemu multifd migration options

Posted by Jiang Jiacheng 1 year, 3 months ago

Add qemu multifd migration options to set multifd-compression
multifd-zlib-level and multifd-zstd-level.

Jiang Jiacheng (3):
  Add public API for parallel compression method
  qemu: Add qemu parallel migration parameters
  virsh: Add options for multifd migration compression

I think what you are adding here is a new parallel compression method and parallel compression level option,
and a specific implementation for the QEMU driver?

Thanks,

Actually, those compression method and compression level option has been
supported by QEMU since 5.0. I want to add interfaces for them in libvirt.
