[SailfishDevel] Can't start VMs (Connection refused)

I'm also having this problem very often.
You can fix it by regenerate the ssh rsa keys, that the SDK uses to
authenticate with the Mer VM ssh connection and replacing the old public
key in the authorized_keys file with the new public rsa key in
$HOME/Sailfish_SDK_install_dir/emulator/ssh/root. You can do this by
opening a shell/terminal and running the "ssh-keygen -t rsa" command and
then when it asks where to save the key pair enter
"$HOME/.ssh/mer-qt-creator-rsa" and when it asks you whether or not to
overwrite the existing key pair with the same name enter "y" (yes). Now
you have to navigate to the (hidden) $HOME/.ssh directory (you can
toggle "show hidden files" with ctrl+h in "Files/Nautilus"(GNOME), alt+.
in "Dolphin"(KDE) and ctrl+. in "Thunar"(XFCE) or by checking the "show
hidden ..." option in the view menu in all file managers if I recall
correctly). Now open the mer-qt-creator-rsa.pub file with a random text
editor and copy all it's contents with ctrl+a and ctrl+c.
then navigate to the $HOME/Sailfish_SDK_install_dir/emulator/ssh/root
and replace the contents of the authorized_keys file with the contents
you just copied from the mer-qt-creator-rsa.pub file. Do the same with
the authorized_keys file in
This should fix the connection refused issue. I've noticed that it seems
that when you close the VMs in another way then clicking the "stop SDK"
and "stop emulator" buttons you often get the "connection refused" error
the next time you start the Sailfish SDK. Possibly this has something to
do with corruption/damaging of the keys when abruptly ending the ssh
connection between the emulator/Mer SDK and Qt Creator/your host system.
Although I've haven't got any evidence for this ;)
I hope this is helpful,
