[ovirt-users] Re: 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?

Hi Bernhard,
With the latest version of the ovirt-imageio and the v2v we are performing
quite nicely, and without specifying
number I can tell you that weakest link is the read rate from the vmware
data store. In our lab
I can say that we roughly peek ~40 MiB/sec reading a single vm and the rest
of our components(after the read from vmds)
have no problem dealing with that - i.e buffering -> converting -> writing
to imageio -> writing to storage
So, in short, examine the read-rate from vm datastore, let us know, and
please specify the versions you are using.
