At the moment running a guest will tie it to the console where kvmtool
is running on. So one cannot logout of the terminal without killing the
guest. Existing workarounds are running in a terminal multiplexer like
screen or using the --tty option to detach kvmtool from the very
beginning.
Both of these solutions need to be invoked at guest creation time,
though. Patch 2 introduces a "detach" command, which can be invoked at
any point during the guest's runtime using the terminal escape sequence
("Ctrl+A d" by default). This will redirect the guest's serial output
to pseudo-terminals and detach the process from the console. More
details in the commit message.
Patch 1 contains a bugfix, which avoids the kvmtool terminal thread to
hog the full CPU time because poll() is not exactly doing what we think
it does.
Please have a look and comment!
Cheers,
Andre
