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.<br> <br> 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).<br> <br> I could use some advice on how to move forward with this. I've started at <a href="https://help.ubuntu.com/lts/serverguide/libvirt.html" target="_blank"> https://help.ubuntu.com/lts/serverguide/libvirt.html</a> for initial information.<br> <br> 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: <a href="http://stackoverflow.com/questions/31302871/trouble-using-virt-install-on-ubuntu-to-create-vm-just-hangs-after-displaying" target="_blank"> http://stackoverflow.com/questions/31302871/trouble-using-virt-install-on-ubuntu-to-create-vm-just-hangs-after-displaying</a> ). 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.<br> <br> _______________________________________________<br> libvirt-users mailing list<br> <a href="mailto:libvirt-users@redhat.com">libvirt-users@redhat.com</a><br> <a href="https://www.redhat.com/mailman/listinfo/libvirt-users" target="_blank">https://www.redhat.com/mailman/listinfo/libvirt-users</a><o:p></o:p></p> </blockquote> </div> <p class="MsoNormal"><o:p> </o:p></p> </div> </div> </div> </body> </html>
