OpenNebula

I think this affects both the attach_nic and detach_nic. Detaching the nic also requires a type bridge argument which may not work.

I have this problem too even when detach_nic, anybody does find any solution?

I thought it was an occasional use case to attach new nics but I try to use it quite often ;-)

Thanks.

today, I upgrade to opennebula 4.4 beta2, but still I cant attach new nic and problem still exist..

Apparently the second argument to the post script is mal-formed. It shows '' but it should be something like one-117. What happens if you do onevm show -x 117 ?

Nevermind, bug confirmed. Fixing...
