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

Hello Friends,

virtualization environments and implements a prototype on the top of KVM.

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+
ition file and create a VM manually (through virsh)
--- use qemu & kvm compiled from the Git sources referred to by you.
Your opinion ?
Thanks in advance,
Alex

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).

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 ?

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:
