MacOS: Qemu: aio=native was specified, but is not supported in this build

[juanluispaz]

Hello,

I'm trying to run capstan on MacOS, but I got an error

Instation process:

brew install qemu
brew install go
go get github.com/cloudius-systems/capstan

Command executed:

capstan build -v -p vbox

Output:

Building projects...
qemu-system-x86_64: -redir tcp:10000::10000: The -redir option is deprecated. Please use '-netdev user,hostfwd=...' instead.
qemu-system-x86_64: -drive file=/Users/juanluis.paz/.capstan/repository/projects/projects.vbox,if=none,id=hd0,aio=native,cache=unsafe: aio=native was specified, but is not supported in this build.
dial tcp [::1]:10000: getsockopt: connection refused

Thanks

If I drop aio=native in the file hypervisor/qemu/qemu.go it works, but when I try to import the virtual machine in VirtualBox 5.1.10 I got an error
