[Xen-users] HVM creation problem

[Dumeen abeywickrema <dumeen@xxxxxxxxxxx>]

Hi,  
 I'm kinda new to XEN stuff, and I've been trying to create a fully virtualized guest on CentOS 5.3 for almost 3 months and no luck yet. I approached this process through several methods, one with virt-install and creating config file manually.
Following is what happens when I try to create a guest, and I have included qemu-dm and last part of  xend.log logs below too.   Please assist me with creating a fully virtualized guest.
(I have enabled the hardware virtualization from system bios)

Thank you,
-D

  When I use virt-install the domain creation hangs at :
  ..........................
         Starting install...
         Creating storage file...                                 | 5.0 GB     00:00
         Creating domain...                                        |    0 B     00:00
...........................

At this point 'xm list' displays :
..............................
 Name                                      ID Mem(MiB) VCPUs State   Time(s)
Domain-0                                   0     2946     2 r-----   2681.3
myvm                                         5      51 9     1 r-----     46.9
................................

If I try "xm console myvm" it doesnt do anything but hangs the whole screen,
vncviewer doesnt work either it says :
