Hello,
 I encountered a ~6.0 load avg in idling guest, HN reports 0,0,0, cpuusage
stats both from guest and from HN suggest that host is idling, but loadavg
says 6.3,6.0,6.2 .
 Temporary workaround: after 'vzctl chkpnt guest' and 'vzctl restore guest',
guest started reporting correct values.
 Guest is running only postgres database, both HN and guest are amd64
running on intel.

I've got dev machine with the same problem:
eyck@etchdev386:~/40m-ovz/work$ w
 11:55:58 up 3 days,  2:41,  1 user,  load average: 129.00, 129.00, 128.96
on HN:
codev64:/etc/vz/conf# w
 11:56:20 up 3 days,  2:43,  7 users,  load average: 0.00, 0.00, 0.00

the guest in question is really idling.
 One thing that those two machines have in common, is that I played with
adding/removing cpus from the guest (oh, and they are both amd64, although
one guest is amd64 and another is i386).
