Re: New with Libvirt and having problems.

      Ah I never gave KVM or virtualization a try in Gentoo.  None
        of my servers have X though using X11 forwarding still works.
         In CentOS the package is xorg-x11-xauth 
        , looks like it may be x11-apps/xauth in Gentoo.
    
    No X anywhere in my environment <smile>.  Somehow I normally
    manage!

    
      Does "virsh iface-list" show tap5?
    
    Actually that command errors out:

    
    virsh # iface-list

      error: Failed to list active interfaces

      error: this function is not supported by the connection driver:
      virConnectNumOfInterfaces

    
      For the disk, this is what I have for my virtio disks...
      

            <disk type='file' device='disk'>
              <driver name='qemu' type='qcow2'/>
              <source
          file='/vmstore/images/domain0001.qcow2'/>
              <target dev='vdb' bus='virtio'/>
              <address type='pci' domain='0x0000' bus='0x00'
          slot='0x06' function='0x0'/>
            </disk>
      
    
    My XML had the type wrong, setting it to raw.

    
    Alas, I still see the invoked KVM being passed:  

    
     -drive
      file=/kvms/test1.img,if=none,id=drive-virtio-disk0,boot=on,format=qcow2
    

    The "if=none" is the problem, it needs to be "if=virtio".  KVM is
    also still being passed the "-S" flag as its first parameter, so the
    CPUs are not starting.  

    
      Also maybe add something like this to your virt-install
        line...
      

      "--disk path=test1.img,device=disk,bus=virtio" 

      
    At this point, I'm just editing the XML, its easier.  Once I get one
    working, I can tweak for the others.  Virt-install at least got me
    started.
