vagrant ssh freeze @ssh subprocess exit 255 on hyper-v

[yosuke....@uniadex.co.jp]

hi there.

I try to vagrant up/ssh on msys2/windows 10.

cf. msys2(administrator privilege)

box was hand maid.

vagrant up or halt was success (that means secure key inserted, and smb shared folder mount has succeed).

but, ssh subprocess has exit 255.

following log is a execution of result of "vagrant ssh --debug"

// log

it seems to me that ssh subprocess arguments are wrong.

how can i resolve it?
