Tomasz,

The screenshots seem to indicate a paravirt mmu problem.

Try to patch the x86.c file from kvm kernel module with:

diff --git a/arch/x86/kvm/x86.c b/arch/x86/kvm/x86.c

-       case KVM_CAP_PV_MMU:
-               r = !tdp_enabled;
+       case KVM_CAP_PV_MMU:    /* obsolete */
+               r = 0;


You'll probaby have to do it manually (this disables pvmmu).

With this, some guests fail to start with kernel panic; some have soft lockups all the time. Some don't start at all.

And generally, everything is "dead slow".
