[Xen-users] Kernel 2.2.18 to 2.2.25 as HVM on xen 3.0.3 freeze every 28s or less

[patrice-xen@xxxxxxxxxx]

Hi,

For various bad reasons I must run a kernel 2.2.X and I tried to get it 
running on Xen 3.0.3.
The virtual machine freeze every 28s (or less) for 1-3 secs which makes it 
unusable as demonstrated by:
# while true; do date; sleep 1; done

<missing>

or
# ping my-xen

Any idea what could be wrong ?

I tried default or bvt schedulers (some people reported better overhaul 
behavior for hvm with bvt), I tried with or without any graphical interface 
(sdl). It does not boot at all with 2 vcpus so could not try that.
Any idea ?
