Re: [libvirt-users] libvirt beginner needs to create and start VMs entirely on command line

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? *From:* Jeff Tchang [mailto:jeff.tchang@gmail.com] *Sent:* Thursday, July 09, 2015 11:21 AM *To:* KARR, DAVID *Cc:* libvirt-users(a)redhat.com *Subject:* 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 On Thu, Jul 9, 2015 at 10:57 AM, KARR, DAVID <dk068x(a)att.com&gt; wrote: 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. _______________________________________________ libvirt-users mailing list libvirt-users(a)redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users _______________________________________________ libvirt-users mailing list libvirt-users(a)redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
