only the last one:) the management node is not involved in performance of individual VM
host nodes nor in the console communication
it may be network between the clients and hosts. Then worth checking the VM's guest
load, then host's overall load (that would be that slow storage)

that wouldn't matter, the communication is between the host and SPICE client only,

The users have problem accessing the VMs at times. While they are working on console, it
just gets hang. There is no response to the keyboard. Have look at the resource usage
during this time, CPU and RAM is normal.
