I don't have a direct answer, but something you should check.
On your compute host with a slow VM, do a process list, find the qemu
process for the VM(s) and check the "accel=" setting on the command
line. If it is "accel=tcg" you are running your VMs under software
emulation and they will be slow. You want to see "accel=kvm" on the
If you have tcg, you need to set up your hosts for kvm. This may
include BIOS settings to enable the hardware virtualization features
of your processor/platform.
Refer to your host operating system documentation for the required
steps to enable KVM.
