Revision 35f75462


Added by Michael Tokarev almost 10 years ago

print meaningful error message in case of --disable-vhost-net

When qemu gets compiled without support of vhost-net, any attempt
to use it fails with a very clear error message:

qemu-system-x86_64: -netdev ...,vhost=on: vhost-net requested but could not be initialized

there's absolutely no reason given why it coult not be
initialized, and even strace'ing the process in question
does not reveal any errors. So print a message telling
what's going on.
