I have installed a redhat 8 server in a KVM/Qemu VM guest to prepare for CentOS 8.  The host is running Ubuntu 18.04.  Window resizing does not work at all (it works in ubuntu and windows guests).  Is this a problem with incompatible versions of spice or is there something else besides the spice daemon that I should be looking at.  Does this work correctly under CentOS 6 & 7 Host?

Display device is set as follows (same as ubuntu guest)

Type: spice server

listen type: address

Address: localhost only

port: auto (5900)

TLS port: auto

passowrd: (none, field is blank)

keymap: (none, field is blank)

OpenGL: (not checked)
