Hi everyone,

I have just configured 2 virtual machines using KVM. Those are the commands I used:
kvm -cdrom ../liveCD.iso -boot d -net nic -net socket,listen=:8010 /dev/sda11
and
kvm -cdrom ../liveCD.iso -m 1024 -boot d -net nic -net socket,connect=:8010 /dev/sda12

after that I built a local network between the VMs and transferred a file using FTP. The transfer speed was 270kb/s! Can anyone tell me why it is so slow? My hardware configuration is: Intel Core 2 QUAD 2.6ghz with 2gb of ram and an SATA hard drive. As I copy a file between the virtual machines i am actually copying it from one partition to another(wright?). It shouldn't be so slow. I also tried to copy a file (using FTP again) from the local host on one of the machines(practically downloading the file from my self) the speed was around 6mb/s which is acceptable. But if I transfer something between both machines it is really slow... Can someone tell me if I am doing something wrong? Or if you have any idea why is the speed not good.
thanks a lot.

Maybe the problem is with

Maybe the problem is with your local host not with the virtual machines. Best regards, Product reviews
