KVM Installation Issue - CentOS7 - Dracut error

Post by srinivas_pithani » 2018/06/08 17:32:36

hi there, I am trouble creating KVM VMs on my Dell Poweredge System .

i am using following command
virt-install --virt-type=kvm --name vm02 --ram 2048 --vcpus=2 --disk path=/var/lib/libvirt/images/centos_vm02.qcow2,bus=virtio,size=10 --os-variant=centos7.0 --network bridge=virbr0 --console pty,target_type=serial --location '/root/kvm/centos7/CentOS-7-x86_64-DVD-1804.iso.1' --extra-args 'console=ttyS0,115200n8 serial ks=/root/kvm/ks7.cfg' --nographics

I have no clue on why this error is coming . FYI , if I tried using of the image from http link , it seemed to work , but I have to struggle with command line selection , I dont want to do that way . The checksum of the iso I am using matches and unfortunately I dont want to use VNC as I want this to be automated for faster installations over my farm.

I am directed with this error :

Use -c instead of --location for .iso images.

ks=/root/kvm/ks7.cfg'
SELINUX might prevent access in some cases (when virt-install is not started by a user).

This doesnt help as I get the following error
wrote: ERROR --extra-args only work if specified with --location. See the man page for examples of using --location with CDROM media
I tried removing the extra-args , but doesn't take it further.

When I use the following location for image, the installation proceeds and take me to a text version of GUI installation & I can proceed from there - this is not what I would like to have .

It doesnt take my ks file , thats a different issue , prb not related to this , will check myself.

virt-install --virt-type=kvm --name vm02 --ram 2048 --vcpus=2 --disk path=/var/lib/libvirt/images/centos_vm02.img.qcow2,bus=virtio,size=10 --os-variant=centos7.0 --network bridge=virbr0 --console pty,target_type=serial --location 'http://mirror.i3d.net/pub/centos/7/os/x86_64/' --extra-args 'console=ttyS0,115200n8 serial ks=/root/kvm/ks7.cfg' --nographics

How do you think the virtual machine can access /root/kvm/ks7.cfg?

I want to say that I can install the machine without any kickstart kindof standard install , but the key problem is on why I am being taken into dracut shell .

Have you defined "/dev/root" anywhere ?

If it works if you only remove ks=/root/kvm/ks7.cfg from your virt-install line then I'd say that's pretty conclusive evidence that that is the problem. But that path will be interpreted from INSIDE the VM so will be looking at the VM's /root not the one on your host.
