I've just managed to install the libvirt-bin:amd64 package on the
same machine, on the wheezy-i386 distribution. The output of 'virsh
capabilities' is now reported correctly, and my VMs that required
SandyBridge are now booting.<br>
<br>
Have you any further suggestions?<br>
<br>

<pre wrap="">Hi
On a range of Dell servers containing Intel 64bit processors, 'virsh
capabilities' reports the cpu differently on Debian Wheezy-amd64 and
Wheezy-i386. The results given by the Wheezy-i386 version seem very
wrong (since n270 is an Atom processor). Apart from architecture, the
package versions of libvirt-bin are identical: 1.2.1-1~bpo70+1.
/usr/share/libvirt/cpu_map.xml files are identical. Is this a known
issue? Details for one server are:

Check if all 32 CPUs have *exactly* the same flags, I remember an
issue when we reported a wrong cpu because the probing code was
scheduled on one of them which had one flag missing. If package and
cpu_map.xml are the same, this is the only thing I can think of.
Simple 'grep ^flags /proc/cpuinfo | sort -u' should do. If only one
line is printed out than I don't know where the problem might be...
