Sure: you didn't quote the full error message :) Please try again. >> Please help me. >> Thanks to all in advance. >> >> >> Thanks & Regards, >> Koushik >> > > type isn't a named parameter, it's positional. > > -netdev vhost-user,foo=bar > > Please take a look at the output from -help. look for "vhost-user." Actually, -netdev vhost-user,... is shorthand for -netdev type=vhost-user,... I suspect the actual problem is vhost-user not being compiled in, i.e. CONFIG_VHOST_NET_USED is off. Sadly, this isn't reflected in --help. Screwed up in commit 03ce574442d.
