Thread-topic: Can't boot HVM Win2k8 R2 x64 DVD ISO (Viridian?)

Hi all,


I’m stuck with a peculiar problem.  I have CentOS 5.5 and Xen.  I have numerous Windows 2003 guests and never had this problem.  An application requires SQL server 2008 which is requiring Windows Server 2008.  I downloaded the 2.8 Gig install DVD ISO.  I create a new guest and connect the ISO as hdc.  The system starts and says “Starting Windows” but hangs and no logo image appears.


I burned the same ISO to a disc and it worked fine in a physical machine.  I then changed my new Guest to boot a 2K3 image and that worked fine, as well as a CentOS ISO worked fine.  Back to the 2k8 ISO it hangs still at Starting Windows.


Luckily I find a ton of reference material on this via google.




posts like this seem to depict and describe the problem exactly.  I’ve found numerous others. 


I also found others where the author stated he just tried changing the system memory to random values and had success.  I’ve tried everything from 8 gigs down to 512, 8 CPU’s, down to 1 CPU and all the same results.


They are all referencing the xe command to set params in Citrix XenServer particularly this parameter “viridian=false”.


Most people seem to have good results by setting this, but I cannot find an equivalent mention for non-Citrix XenServer like my CentOS5.   


I have tried editing my /etc/xen/guest config file and adding viridian=0 at the bottom, but still hangs.


Looking here for help.   Here is my config.
