[CentOS] KVM console?

I finally got access to some machines with more resources than the
free VMware ESXi license allows which pushed me into trying kvm
instead.  Seems capable enough for what I need and can even import and
run the existing vmdk images I already have.   But, I have some
questions about accessing the virt-manager console remotely for
initial configuration, etc..   Normally I use freenx for remote GUI
access and it seems to work except that on the Windows guest I tried
the cursor position never stays in sync.   Are there better ways to
get remote access to the GUI or centralize access to a group of KVM
servers?   Or do most people automate the VM setup to the point where
they don't need console access until it is up on the network where you
can connect directly to the guest?
