I've installed Cockpit and cockpit-machines to manage KVM virtual machines. I tried installing Lubuntu through cockpit but it fails with an error:

ERROR unsupported configuration: CPU mode 'custom' for x86_64 kvm domain on x86_64 host is not supported by hypervisor

I want to find the configuration file for the Guest VM because I suspect that the config file has some wrong default parameters. I can't seem to find the config file. Anyone know where it might be located?


This is just a front end to libvirt, so you can use the ordinary libvirt command line tools to manage the same virtual machines. For instance virsh dumpxml <name>, or by running virt-manager to use a desktop app to manage them.
