[PVE-User] Speed problem

[kai at zimmer.net]

Hi Luis, 

growing qcow2 virtual disks can take some time. If you use qcow2, you
could try to grow it before copying via network with 

dd if=/dev/zero of=100M.img bs=1M count=100 (generates 100 MB file) 

... and remove the file before copying - just to see if file system
growth has an impact. 

Also make sure you have unique MAC identifiers for all network
interfaces involved. 

Best, 

Kai
