Hi, I'm having a problem with libvirt.

Since a few days, when I try to create a virtual machine I get the following error and I could not solve it

" Imposible completar la instalación: 'internal error: Cannot find suitable CPU model for given data' "

I tried deleting the / var / cache / libvirt / qemu / capabilities / directory, and restarting libvirt but it did not work.

I have other virtual machines on the physical server and they work fine, but I can not create new ones.

How can i fix this

Thank you
