KVM Virt Manager + SPICE

I am trying to get SPICE-agent to work properly on a KVM Virtual Machine so I can share folders or copy paste from host to VM. I get this error when I try to enable it, even though I installed spice-agent on the host also.

Error starting domain, internal error
QEMU: host doesn’t support expected feature (MSR-490h)

I think the relevant part of the error message is this: failed to open '/home/a/share': Permission denied

Check if that directory exists and if it permits qemu access.
