Hi, It is not really an optimization based only on console connection. In my opinion this should be a decision factor when determining which VM to migrate from an overloaded host. If it is a desktop and no console connection, then it is better candidate than a desktop with console connection or a server with or without console connection. Basically this logic would just want to minimize the pain caused by the short lag when a VM is live migrated.
Can I assume that a Desktop is only used when a console is connected? ----- Original Message ----- > From: "Itamar Heim" <[email protected]> > To: "Laszlo Hornyak" <[email protected]> > Cc: "Yair Zaslavsky" <[email protected]>, "engine-devel" > <[email protected]> > Sent: Thursday, April 11, 2013 1:10:04 PM > Subject: Re: [Engine-devel] watchdog > > On 04/11/2013 01:57 PM, Laszlo Hornyak wrote: > > No what I meant is that > > if the VM is a server { > > not having a console connection to it does not mean that it is not used. > > } > > > > Therefore desktops on the same host with no console connection, they may be > > better candidates for migration.
