Hi,

You can find more information at the "Image Compression" section of the
spice-user-manual.
https://www.spice-space.org/spice-user-manual.html

Also "man qemu-kvm" provides some information:

image-compression=[auto_glz|auto_lz|quic|glz|lz|off]
     Configure  image  compression  (lossless).
     Default is auto_glz.

jpeg-wan-compression=[auto|never|always];
zlib-glz-wan-compression=[auto|never|always]
     Configure wan image compression (lossy for slow links).
     Default is auto.

Uri.
