How does the VMM assign system resources= for each VM? For example, in a multi-core environment, how can I enable th= e VMM to run, say, on a two-core intel's processor while I am able to force= a VM to execute only on a specific core upon initializing the Guest OS ? t= hat is to say, how I can assure the VM to believe that there is only one ph= ysical core running on this machine? What should I do? Is it possible to assign a core when VMM starts a new VM = after the VMM is booted ? Thanks a lot! --_000_373C28B006B97A4BA77CD51D8F89698356C517BEexchpd01_ Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable

Hi, list,

A= VMM provides a VMCS for each VM. How does the VMM assign system resources = for each VM? For example, in a multi-core environment, how can I enable the= VMM to run, say, on a two-core intel’s processor while I am able to force a VM to execute only on a specific core= upon initializing the Guest OS ? that is to say, how I can assure the VM t= o believe that there is only one physical core running on this machine?

W= hat should I do? Is it possible to assign a core when VMM starts a new VM a= fter the VMM is booted ?

   Thanks a lot!
