[libvirt] bug, libvirt, internal error

[CESAR DAVID VASQUEZ ROMERO]

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' "

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

Traceback (most recent call last):

    if ret is None:raise libvirtError('virDomainCreateLinux() failed',
conn=self)
libvirtError: 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
