It looks like that fixed it. I must have been using the x86 version
all along, thinking the amd64 was only for AMD chips, and I have an
Intel.
That's a common mistake, amd64 is an official name for that
architecture because it was AMD who introduced that architecture, but
nowadays x86_64 is used. It's the same as i386 and x86, the original
32-bit architecture was introduced by Intel.
I tried to change the CPU settings to those you recommended, and it
didn't like it. When I use 'virsh edit" for the host, make the cpu
changes, then try to save, I receive:
error: XML document failed to validate against schema: Unable to
validate doc against /usr/share/libvirt/schemas/domain.rng
Extra element cpu in interleave
Element domain failed to validate content
Failed. Try again? [y,n,i,f,?]:
Oh, right, that was my fault, I didn't realize that you probably have
older version of libvirt, try to use this configuration:
<cpu mode='host-passthrough'>
<topology sockets='1' cores='2' threads='1'/>
</cpu>
There is no "check" attribute for "cpu" element in older libvirts.
