It's new behavior i might be disconnected from remote Xen 3.4 Host during
vnc session doing HVM install or just during running HVM via remote vnc
connection. To restore network i always have to reboot Xen Host itself.
I suspect hardware issues due to problems between cheap hub and
Marvel Yukon PC-E Gigabit Ethernet. To scp 4 GB file i always have to replug
network cable to PCI Ethernet ( RTL 8069SC or E8088 )
However, i attempted to switch off tso at HVM DomU:-
[root@FHVM ethtool-6]# /usr/local/sbin/ethtool -K eth1 tso off
Cannot set device tcp segmentation offload settings: Operation not supported
[root@FHVM ethtool-6]# /usr/local/sbin/ethtool -K eth1 tx off
Cannot set device tx csum settings: Operation not supported
Boris.

That's not new behaviour though, is it? You reported VNC failures before. Does disabling GSO
help?
