Fastreboot and VirtualBox

I was getting some work done with virtualbox, vnics and

While VirtualBox does reboot rather fast since it virtualised, but why not faster ? Since the bug with VirtualBox and
OpenSolaris was fixed we should be able. And indeed we are.

By taking out VirtualBox from the blacklist of the boot-config SMF service we can then do Fastreboot within a VirtualBox guest with no issues :)

Let see what platforms are blacklisted.

$ svcprop -p fastreboot_blacklist/platforms boot-config
VirtualBox VMware\\ Virtual\\ Platform MCP55

Ok, lets take out VirtualBox.

$ svccfg -s boot-config:default setprop blacklist/platforms = astring: '("VMware Virtual Platform" "MCP55")'
$ svccfg -s boot-config:default refresh

Now VirtualBox can do fast reboot.

Thanks Darren for the trick with '(..)' for handling multiple strings in the property.

AI SMF profile

AI services get the SMF treatment.

We just moved to b111a bits on our install server and with the
new installadm tools there came another config change. Instead
of the services living in their own little file off /var/installadm/services,
they now reside as properties of a property group within the
svc:/system/install/server:default SMF service.

Instead of wiping all my already unpacked services I wrote a small
script to populate these SMF properties instead. The script takes a file in /var/installadm/services> and populates the
SMF services as needed.

Lastly all was needed is a svcadm start svc:/system/install/server:default to get
things going.

What any 'cloud' based app/service will have to beable to beat

What any 'cloud' based app/service/api will have to be able to beat in terms of self-serviceability
(i.e. upgrading itself), propagation over new compute nodes, speedy integration new features..

All that good stuff.

It'll have to match what the Conflicker virus already can do.

Adding a disk image to a xvm/xen guest

Adding a disk to a linux guest.

Create a 16GB vmdk format sparse disk image:

/usr/lib/xen/bin/vdiskadm create -t vmdk:sparse -s 16g -c "extra disk" /path/to/disk/dir

Attach that new disk image to a guest:

virsh attach-disk virtual-guest /path/to/disk/dir xvdd --driver tap --subdriver vdisk

Note the use of 'xvdd' for the disk name that the linux will see the disk as.

Then one can add the disk to the linux guest's /etc/fstab:

/dev/xvdd1 /export/dsk1 ext3 noauto 0 0

And off one goes

Solaris USB devices

My other entry on gettng me canon 400D working with Solaris had one
little thing in error. I used update_drv(1M) thinking it was needed
for the ugen(7D) driver to attach correctly. Its not the case. We
don't need no update_drv(1M) for usb devices anymore (really). The
system will do everything needed (or its a bug).

This functionality was introduced into solaris via this bug; 6213551 libusb support should just work thanks a lot to Frits and the usb guys.

A FAQ is available as well
as the ugen(7D) manpage.
