I read that , but am not sure how to switch the emulation to rtk in
XenServer 6. Anyway, in PV mode it seems to work better, although I
had several occasions in which under load it stops any network access,
ifconfig down/up does not cure it and has to be rebooted from the
console (but that is a different matter, of course).
