Hi all,

I'm creating NAS4Free dom0 edition.
This is simple wrapper of Xen/dom0/FreeBSD.

You can upgrade by same way of NAS4Free.
You can manage HDD, ZFS, iSCSI target, NFS share by same way of NAS4Free.
You can manage DomU(VM) via WebGUI.

NAS4Free dom0 topic in English:

Latest download:

How to install:
1.Download LiveCD iso image.
2.Burn to CD/DVD-RW blank disc.
3.Boot from it.
(if your server don't have an optical drive, please use an external USB optical drive)
4.Install to USB Flash drive (2GB or more) from menu #9.
5.Reboot the server after ejecting CD/DVD media.

How to upgrade:
1.Navigate to System|Firmware in global menu from web browser.
2.Click "Enable Firmware Update".
3.Select NAS4Free-dom0-embedded-*.img.xz. (don't decompress the image)
4.Click "Upgrade Firmware".

At least you need a bridge interface before using.
Please create it from Network|Interface Management|Bridge.
You can change boot parameters from System|Advanced|loader.conf.
If you are interested in the xl.cfg, it is created in /usr/local/etc/xen/vm-<VMNAME>.cfg.

Known issues:
uuid generation of ports/sysutils/xen-tools is broken. You cannot control by UUID.
(quick hack patch is attached this mail)
xnb device performance is terrible.
(it eats 100% CPU on intr while transferring via bridged 10GbE)
If you don't know about NAS4Free, here is the key feature of NAS4Free:

multiple architecture image for amd64, i386, rpi, rpi2, odroid-c1.
running on memory disk. (no write access on boot device)
minimum memory requirement is 512MB.
single configuration file. (except extra service like vbox, syncthing)
one click disk import. (easy hardware switchable)

Enjoy Xen dom0 and NAS4Free collaboration!
