Hello Friends,
Would you please tell me how to reset a VCPU programmatically ? That is ,
force it reload like during cold reboot.
Thanks,
Alex Binun
Eric, I aplogize for making your work complicated.
Should I send questions to libvirt-us...@redhat.com instead ? I would ask more
questions.

Dear Friends,
Thanks for your assistance!
We would like to ask you a question about the KVM internals.
Our module includes a timer which (once in every second) fetches the IDT value
of every online VCPU in the system using the kvm_x86_ops->get_idt ; the code
looks like:
struct kvm_vc
id.html)
and send kill to this ID from the command line, the corresponding VM shuts off!
Which magic does the manual method in order to succeed ?
Thanks in advance,
the Israeli team

I am trying to observe the memory/disk/network accesses done by a VM. The
resulting log can be used to decide whether a VM initiates a malicious action
(because , say, it runs a malicious software).

--- use qemu & kvm compiled from the Git sources referred to by you.
Your opinion ?
Thanks in advance,

Hello Stefan,
The qemu used by me is the one installed using apt-get install qemu. The
executable is in /usr/bin. The KVM driver is the one supplied with Ubuntu 13.04.
The version of qemu is 1.4.0 (after running qemu --version I get the message
--- QEMU emulator version 1.4.0 (Debian 1.4.0+
