[drbd-mc] Cannot clear VNC password + feature requests

[Caspar Smit]

Hi Rasto,

First of all, thanks for all the improvements in the latest version.

1) When I create a VM and change the VNC password to 'something' it is not
possible to clear this password later on.
It is only possible to change the password in something else but the
password field is already empty when editing so I cannot apply to clear it.

2) Any ETA on the TODO list item (my feature requests from a couple of
months ago) about the console window which stays active after shutdown of a
VM?

>> -When I shutdown a VM from the VNC console, the console stays 'active'
>> even if the VM has shut down, it would be nice if the console is
>> closed when the VM has shutdown.

>I've put that on my TODO list.

3) It would be nice if LCMC supported specifying the amount of cores per
socket.

I have a system with a quad-core CPU and i noticed that when adding 4
cpu's to a Windows 7 VM, Windows 7 only sees 2 processors.

Here's why:

The vcpu switch defaults to giving the vm <no. op cpus> physical
processors (4 CPU sockets in other words).

So to windows this is like having a motherboard with 4 CPU sockets
with 4 CPU's (each with 1 core).

Since all windows desktop versions (including Windows 7) have a limit
of supporting up to 2 physical processors, is the reason why Windows 7
only sees two processors.

But Windows 7 is perfectly able to see a single cpu with 4 cores or 2
CPU's with 2 cores each for instance.

There is a <cpu> switch in the domain XML format documentation where you
can specify this:

In case no restrictions need to be put on CPU model and its features, a
simpler cpu element can be used. Since 0.7.6

  ...
  <cpu>
    <topology sockets='1' cores='2' threads='1'/>
  </cpu>
  ...


So in order to get a quad core windows 7 VM it is needed to specify:

  <cpu>
    <topology sockets='1' cores='4' threads='1'/>
  </cpu>

Let me know what you think of this feature.

Kind regards,
Caspar Smit
