slow "KVM Host" in EL6 ?

[Dmitry Makovey]

Hi everybody,

we have some weird problem with EL6 box which serves as a KVM host for 3 VMs 
currently. It shares the same interface with all 3 VMs (same network). All 
works, except from time to time machine behaves very slow in console (ok, SSH 
connection) and it happens only from time to time. 

We've got vnstat running on that box. There is no sign of network overload so 
far. Average load never crosses 1 (actually it's in 0.2 neighbourhood) so 
we're really at loss.

Did anybody experience something similar? Any suggestions on where to look?
