VirtualBox 2.2.2 and OpenSolaris build 114 and above - new vbi kernel module necessary

If you run OpenSolaris with a kernel build 114 and above with VirtualBox 2.2.2, you will have incompatible data structures between the kernel and the VirtualBox kernel module. Lucky Solaris users see this very infrequently, but from time to time, these type of changes seem to be necessary. Your Solutions is until the next VirtualBox release is out, to use the kernel module package attached to the VirtualBox ticket http://www.virtualbox.org/ticket/3981 (and never try the one from Release 2.2.2 on a kernel build 114 or above :-).

How I got there. My workstations runs build 114 since a few days and I wanted to use VirtualBox 2.2.2 to do some real work with it. But unfortunately the whole machine rebooted if I started the Guest. I wrote an email to the VirtualBox Team once I googled the problem and found the ticket mentioned above .... promptly I got a reply that the new kernel module package has already been attached to the ticket right now (I had the ticket from a few minutes ago w/o the file attached still on the screen). Wow, that was fast! Thanks to the VirtualBox Team!


PS: I'm really really happy, that the Solaris kernel doesn't change it's interface and datastructures every fortnight. Datacenter customers need this as well as Homeusers and Developers and Softwarevendors and everyone .... ?
The response from the VirtualBox Team was so fast, you won't believe me if I tell you how fast.

Using Tim's ZFS Automatic Backup 0.1

Automatic backups of ZFS filesystems - Tim Foster's  zfs-auto-backup. This is really cool and now available as a SVR4 package.

Usage:
Just plug in your USB-stick or USB-Disk and if the Name (=Label) of the media matches the one preconfigured in a SMF-property, the full- or differential backup starts automagically.

If you like to try use this yourself on OpenSolaris, you may install the scripts manually as Tim describes in his blog or use this SVR4 package download: SFEzfs-auto-backup.pkg. The package is build from Tim's zfs-auto-backup-0.1.tar.gz with the Common Build Environment (CBE)

Installation:
install the package: (prepend "pfexec" if your userid owns the RBAC profile "Software Installation";)

pkgadd -d SFEzfs-auto-backup.pkg 

then plug in your USB-media and look into /media which label-name your media has. For example "NO NAME" (be carefull, you might have more then one of this label...) or "MANUFNAME". Take this name and register it as your backup-media:

svccfg -s svc:/system/filesystem/zfs/auto-backup \\
setprop zfs/volume = astring: "MANUFNAME"

Then add a new user-defined attribute to your zfs filesystems to be backuped: (replace "zfs/tmp" with your filesystem, beware of recursion!) 

zfs set com.sun:auto-backup=true zfs/tmp

If you like verbose logging of theSMF service:

svccfg -s svc:/system/filesystem/zfs/auto-backup \\
setprop zfs/verbose = boolean: true
tail -f "/var/svc/log/system-filesystem-zfs-auto-backup:default.log"

The First Snow


Our first snow in southern Germany arriving timely. As promised by the weather forecast for sea
levels above 600 meters. Our sea level is 640 meters (around 2100 feet). Very accurate forecast.


Back of my home



What do the kids think about the first snow?
