[Spice-devel] While running win xp guest x86 cpu spikes on host and guest lag and are some times unresponsive

[Nreaction at gmail.com]

Guest starts fine but issues start after media is started in guest(IE  
playing a song with visual effects). Usually with in the first 10 mins the  
host Starts to lag even at the physical terminal. At this time the whole  
system is almost unusable (On some occasions the system seems to recover  
after about 5 mins and stops lagging.) until i kill the qemu-kvm process  
and even then the system lags for another minute or two after the process  
has been killed. Once guest is down system begins to become usable again.  
Any Ideas?
