Hi,
For a backup of data from a VM to a USB mounted disk I want to
circumvent the USB 1.1 limitations on the guest and instead copy the
data over to the host using scp/ssh. I have setup a network using virtio
and NAT like this:
<interface type='network'>
<mac address='52:54:00:6b:0d:36'/>
<source network='default'/>
<target dev='vnet1'/>
<model type='virtio'/>
<alias name='net1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
</interface>
When I now create a 1GB file using dd and copy it over from the guest to
the host, I am seeing a performance between 25-30 MB/s.
My question is if this is normal because I have seen others on the
internet achieve far greater speeds.
In any case the speeds are comparable to current USB 2.0 speeds but I
intend on using USB 3.0 so would like to get a little bit more out of it.
What would I use to speed this up a bit futher?
Cheers
Erik
