Re: [Xen-users] Xen - Windows - Sandy Bridge

[Grégory Maingret <gmaingret@xxxxxxxxx>]

Thanks for the link, I've learned several things.

About my problem, following the XenCommonProblem link, I tried xm dmesg | grep -i hvm and yahooo I have VMX enabled :), but have not VT-d.

==Now, when I run xm start win7.home.local, I get
Error: _refreshShutdown
Usage: xm start <DomainName>

Start a Xend managed domain
  -p, --paused                   Do not unpause domain after starting it    
  -c, --console_autoconnect      Connect to the console after the domain    
                                 is created
  --vncviewer                    Connect to display via VNC after the       
                                 domain is created
  --vncviewer-autopass           Pass VNC password to viewer via stdin and  
                                 -autopass

It seems to be the "most stable" error I had...
I've seen patch for qemu or python on the web but I don't know how to use them (with lines beginning by + then by -)

If someone know the answer (except 42), I'd be glad to pay him/her a beer (the next time he come to Cannes).
