Re: [Xen-users] PVM + Network Interface

Ian,

The output of command is:

driver: vif
version:
firmware-version:
bus-info: vif-0
supports-statistics: no
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no

But, the transfer not more than this (rsync output):

sent 4.46M bytes received 101.66G bytes 12.11M bytes/sec

Thanks,
Diogo

I think "ethtool -i eth0" will tell you which driver is being used. If
it is "xenvif" or anything like that then it is PV, if it is e1000 or
rtl81?? etc then it is emulated.

You might also want to check the wiki e.g.
