[ovirt-users] Slow vm transfer speed from vmware esxi 5

Hi, currently I'm trying to move VMs from our vsphere 5 environment to oVirt. While the io performance on oVirt and on the esxi platform is quite well (about 100MByte/sec on a 1GBit storage link) the transfer speed using the integrated v2v-feature is very slow (only 10MByte/sec). That would result in transfer time of >24h for some machines. Do you have any ideas how I can improve the transfer speed? Regards Bernhard Dick
