Using loadvm with snapshot

Hi,

Are there plans to support using -loadvm with -snapshot?

I saw some past discussion on mailing list including bug that was closed 
earlier this year but no recent activity:

https://lore.kernel.org/qemu-devel/162424905685.11837.7303570061857383641.malone@loganberry.canonical.com/

Testing with latest qemu it looks like -loadvm still does not work when 
combined with -snapshot.

I'm curious how complex it would be to implement this feature and if it may 
show up on QEMU roadmap in the future. Or if there is alterative command that 
can be used to save the state of a running VM and then use the same qcow to run 
multiple QEMU instances loading this VM state running in snapshot mode.

Thanks,

-Gabriel
