Hi Guys
Looking through my session notes from UDS-Q I've spotted a few
work items related to UTAH features:
1) USB Installation Support
This definitely seems worth supporting, we'll just have to figure
out how to do it in libvirt. Right now we support virtio, sata, or
ide as the diskbus for a disk, and if it's as easy as just changing
that option, then we can have support very quickly.
Probably - you might also be able todo it with the CustomVM class as well.
2) Multi-NIC Support
The CustomVM class actually has support for this. If you pass a VM
XML definition file with multiple interfaces, it will rewrite them
all to have random mac addresses. The class supports specifying a
list of mac addresses to use for the interfaces, but the frontend
script doesn't currently have a way to pass that in. If you want
that, I can add it very quickly, but even without any changes, we
should support an arbitrary number of NICs, we'll just be using
random mac addresses for them.
That would be great - yes please. I don't really care about the mac
addresses - just having more that one would be greate!
Cheers
James

I've attached a sample VM XML file that you can try. It includes two
network interfaces, and sets the cdrom device to present as a usb device
on sda. It doesn't look like it's currently working on the precise
desktop image, so we may need to make some tweaks. It does work on the
alternate image, however. This is also just me using a CD ISO and
telling libvirt it's a USB disk, so maybe desktop will work with an
actual USB disk. In any case, both of these things can be handled by
customizing the VM XML passed to the current code. If we need more
options for them, I can work on integrating those.
