Hi,
could you please run the following command on the non responsive host and
post the output here?
virsh domcapabilities
Also, could you please go to the Webadmin UI and check the warning signs on
the host list and host detail to see, what flags is the host missing? You
can also check the CPU Type on the host's detail page + all available cpus
in the info icon next to it.
Regards,
Lucia
