CentOS - Jul 2019 - Creating KVM-based VM with virt-manager and virt-install on C7

Hi folks,

for learning purposes I create KVM-based VM with the virt-manager. Later 
I get rid of the VM and repeat the "process" again. When recreating
the
VM I always enter the same values into the wizard in virt-manager (i.e. 
I want to speicfy a given MAC).

I'd like to "automate" this procedure, all of what I do in
virt-manager
for creating the new VM, I' d like to do it with a bash script using 
virt-install.

I' wndering if it is possible to "record" the values when I enter
them
into virt-manager and extract those values for usage with virt-install? 
It's not clear to me when I enter a field in the wizard what is the 
corresponding parameter in virt-install.

Regards,

Meikel

Hi,

I think your looking for:

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/virtualization_deployment_and_administration_guide/sect-domain_commands-creating_a_virtual_machine_xml_dump_configuration_file

After you have built the a VM in virt-manager say, with ith this XML
file you can recreate the same VM, modify if needed and create other
VMs etc.

Regards

Phil
