Yes. It creates a Linux machine, and Condor works just fine on Linux.
You will need to set up bridged networking in order for it to work
well, and have a DNS entry for it. You can use GCB if you have your
VM instance set up as a NAT network connection.

Both Linux and Windows.

It will run two jobs at once. 

The new VM-awareness code we're adding to Condor will allow startds in
a VM to know what the startd on the host is doing, and to incorporate that
into the policy expressions inside the VM.

We're also going to change the name of the Condor VM (like vm2@xxxxxxxxx),
since it's clear that having to things that are "VMs" in Condor is confusing.
We're probably going to call it a "cslot" instead of "vm"
