[libvirt-users] Hello world help needed
I am trying to work my way up the learning curve through
a forest of conflicting and mostly non-working examples
and help pages spread about the internet.
I have had no trouble getting a basic vm to build
and to then start it up. But I have utterly failed
to gain access to the machine.
The only host I have available that can run it is a
remote server. I have not got the networking side
working yet, but I can live with that for the moment
because I have thus far not been able to get access
to a simple console on the vm.
Here is the machine:
<domain type='kvm' id='2'>
<name>ubuntu</name>
<uuid>8904d893-87dc-dc1f-0219-486745a370f6</uuid>

I dumped the original and added the pty stuff from an example, but
when I create it and connect to the console:
# virsh -c qemu:///system create ubuntu2.xml --console
Domain ubuntu created from ubuntu2.xml
Connected to domain ubuntu
Escape character is ^]
nothing appears and nothing I type echoes.
At least I can escape though...
I seem to have no trouble creating them, but it sure would
be nice to be able to access them.
Oh, and btw. Every time I create a VM with the ubuntu
ubuntu-vm-builder kvm hardy --mem 256 --iso /path/to/ubuntu-8.10-server-i386.iso
ubuntu-vm-builder kvm lucid --mem 256 --iso ubuntu-10.04-server-amd64.iso
It leaves a loopback disk behind that never goes away. I've
had to reboot the server once already and upped loop_max to 32
so I would be able to work longer before doing so again.
