I have install Virtualbox on a CentOS machine. The guests are CentOS machines too. Their kernel is 2.6.18-194.3.1.el5 and they are CentOS 5.4.
The problem is that scp'ing files from a the guests to the host (or viceversa) is very slow (60.0KB/s).
scp'ing from a guest to a remote machine is instead very fast (11MB/s).
I searched on Google and there is a problem with a Linux kernel but it is not the one I am running.
I don't know what to do. I really need to copy files between machines at a reasonable rate.
I hope somebody can help.
