I want to obtain the CPU state(context) and devices state for a VM ,I tried using libvirt library in python but it din't work ...Is there any way to obtain the CPU state of a VM.. Please help !!

does virt-v2v also restores the memory and cpu state ?

2014-02-28 11:41:16 -0500 answered a question Is it possible to migrate a VM between heterogeneous hypervisors?

what i did is , i created a virtual machine on xen using virt-manager, installed ubuntu 12.04 on it then installed grub on it,installed some packages and created some dummy files, and then turned off the virtual machine, then using NFS i shared the .img i.e the storage with another machine with kvm installed on it, then deployed a virtual machine with same configurations on the kvm machine and just used the shared .img file as storage while creating the VM and it worked !!!! .

Note: when i started the virtual machine for the first time using virt-manager on KVM machine , it promted to try ubuntu or install it, but when i rebooted it, it booted the OS with previously installed settings (i.e along with the user accounts, packages and dummy files that i created when the VM ran on Xen)

so what is the need of using tools like virt-v2v for conversion if we can directly use the storage ?

2014-02-01 04:03:12 -0500 asked a question What exactly happens when I migrate a virtual machine on a Xen hypervisor?

I am curious to know what all things happens when a virtual machine is migrated from one Xen host to another host using the following command:

host1: xm migrate --live fedoraVM host2

If anyone knows any source of information regarding detailed processes that take place while migrating a VM between XEN hypervisor or KVM hypervisors please do let me know.

As far as i know vm migration is the functionality provided by hypervisors, so what exactly is the role played by openstack in the process of live migration? Does it just provide a secure way for transferring the information from one hypervisor to another or just a UI?
