On the host, it's expected, I've got two qemu-kvm process loading up
100% cpu. Within the guest VM, top looks like this, high load but low
cpu %.
top - 10:21:40 up 1 day, 59 min, 0 users, load average: 16.72, 6.05, 2.29
Tasks: 176 total, 1 running, 175 sleeping, 0 stopped, 0 zombie
Cpu(s): 3.3%us, 1.2%sy, 1.2%ni, 91.2%id, 2.7%wa, 0.1%hi, 0.2%si, 0.0%st
Mem: 1017392k total, 970564k used, 46828k free, 1436k buffers
Swap: 2040244k total, 200572k used, 1839672k free, 30344k cached

I think the network is responsive, pings work but nothing else does.
No error messages in both host and guest. faillog, messages and dmesg
give no clue. Which is why I figured I really need to be logged in,
check and if necessary kill innocent processes one by one until I find
the culprit when it's going crazy.
