Re: [libvirt-users] libvirt beginner needs to create and start VMs entirely on command line
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:
virt-install \
--name example \
--vcpus=4 \
--disk /data/example,size=80 \
--ram 2048 \
--graphics vnc,password=**********,listen=0.0.0.0,port=15916 \
--accelerate \
--cdrom /var/kvm/ubuntu-14.04.1-server-amd64-autoinstall.iso \
--os-type=linux \
--noautoconsole \
--network network=default \
--boot cdrom,fd,hd,network,menu=off
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...
). 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.
