Hi, i've been using cado-nfs in virtual machine (vmware and virtual box)
So far, it works well, but today i've exported the vm (which cado-nfs
has been installed) and try to use it with another computer. I expect
it to work there as well as it does on my computer vm. However, it
doesn't. It shows some error like this
