Thanks for replying. Good info so far.
After I start the VM, I’m going to need to see the boot console, and I’ll need to ssh into it with a hostname or IP. What are some required steps for those needs?
This VM is going to need to access a few associated networks. I can see that the “—networks”
option is part of the interface for configuring this. What are some things I’ll have to do for this?

I actually find I do almost all my VM management inside the virsh command.
If the VM appears to exist inside virsh but is in a shut off state then you should try to start it.
VNC can also be SSH port forwarded (which I have done before).
Not sure if this will help but this is the command I use to create VMs:
--disk /data/example,size=80 \
--graphics vnc,password=**********,listen=0.0.0.0,port=15916 \
--cdrom /var/kvm/ubuntu-14.04.1-server-amd64-autoinstall.iso \
--network network=default \
I also edit the XML file sometimes. Notice I have the autoinstall iso. Basically I went through and created a ks.cfg file after extracting the ISO file to a directory. Then I ran a command like this:
mkisofs -D -r -V "auto install" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table
-o /var/kvm/ubuntu-14.04.1-server-amd64-autoinstall.iso /root/serveriso

I'm a beginner to libvirt and creating VMs, for that matter. I have a set of specifications for VMs I need to create and log into, but I have to create them on an Ubuntu box that I only have ssh access to. I won't have desktop GUI access,
although I do have dynamic port forwarding, so I can access a browser GUI from my desktop.
Reading through the libvirt info, I see numerous mentions about using VNC to do additional work, but I won't be able to use VNC (not allowed within our firewall).
I could use some advice on how to move forward with this. I've started at
https://help.ubuntu.com/lts/serverguide/libvirt.html for initial information.
I managed to create a disk image for my first VM, and I believe I created the first VM using an ISO (based on CentOS, I believe), but I'll probably have to rebuild that, because I think I have to configure networks on the VM, which I didn't do on initial creation.
I was confused by the initial results from "virt-install", because it seemed to hang after a second or two (I posted this SO question about this:
http://stackoverflow.com/questions/31302871/trouble-using-virt-install-on-ubuntu-to-create-vm-just-hangs-after-displaying ). The reply from this makes it seem like it was trying to present a GUI for next steps, but I of course never saw that. The VM appears
to exist, but in a "shut off" state.
