When migrating a VM from one standalone server to another, I noticed
that there's a huge gain in making sure the VM has xs-tools installed:

VM: Centos 6.3 x86_64 - PV

- with xs-tools installed:
206 packets transmitted, 205 received, 0% packet loss, time 205680ms
rtt min/avg/max/mdev = 0.204/48.439/197.497/78.066 ms

- without xs-tools installed:
209 packets transmitted, 157 received, 24% packet loss, time 208432ms
rtt min/avg/max/mdev = 0.217/66.975/196.220/84.136 ms

In both cases the VM seems to appear in XC within 1-2 seconds on the
new server, but without xs-tools, it doesn't seem to do any networking.

I dont know if this is normal or not, but I guess it has something to
do with some optimized drivers/modules?
