Subject: Update on VM support
Date: Tue, 15 Apr 2014 21:58:58 +0200 [thread overview]
Message-ID: <87lhv6z7nh.fsf@gnu.org> (raw)
Hello!
A summary of the recent changes in (gnu system vm) & co.:
• This module now uses QEMU’s 9p file system support (-virtfs) to
share files with the host (previously it used Samba to expose a CIFS
share to the guest, because that’s what QEMU made easy to support
historically, but it was much slower, less flexible, and required a
custom patch to share more than one directory.)
• The build-side part of the code has been moved to (guix build vm)
and modularized. It is much more readable and flexible now. :-)
• When building a VM that shares its store with the host, as with
‘guix system vm’, unionfs-fuse is used to get a writable file
system. That file system is the union of the real root provided by
the image, which is read-only, and a writable tmpfs.
That improves development and testing with ‘guix system vm’. Some of it
will also be reusable for the installation CD/USB key image.
Ludo’.
