Hello everyone.

I have a problem using VCPU and memory on HVM Guest OS.

I've seen this bug, http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=776,
and I have the same symptoms :

xen0dmze3:~# xm li
Name                                      ID Mem(MiB) VCPUs State   Time(s)

xen0dmze3:~# grep vcpu /etc/xen/gobelin.cfg
# Should be at least 2KB per MB of domain memory, plus a few MB per vcpu.
vcpus=4

gobelin                            8     3     -   --p       0.0 any cpu

I'm on a double QuadCore (meaning 8 PCPU).

On the Guest OS :

I have installed the SMP Kernel, and still don't know what to do :(

The usual logs can be found here : http://dedibox.tib0.com/~tibo/

Thanks for any help !
