Thanks for your comments.

At ParaVM GuestOS, it uses real mITC as vITC(=mITC).

Hi, Kevin
Thank you for your comments.
I agree your points.
I will change it as your comments.
Anyway, I should change the name of function(vcpu_get_next_timer),
because the meaning is changed.:-)

Hi, Yamahata-san,
Thank you for your comments.
In IA64, ITM/ITC model is used.(for example *1)
This IA64 model is different from x86 timer model.
So It needs to send a correct ITM/ITC interrupt to Guest OS by using VIRQ_ITC.
This VIRQ_ITC signal timing is controlled by the Guest OS itself.
So
Hi, Tristan.
I have no idea without changing the linux scheduler code.
I also want to know the idea to solve your problem.
If the linux stops over 10 seconds, it appears.
On Xen, that problem is common in x86/VTx, IA64/noVTI and VTI.
Thanks,

More exactly safe_halt() is paravirtualized using

Xen/IA64 doesn't support HYPERVISOR_set_timer_op(), but it
would be quite easy to add its support.
