I tried to install the OVM 3.1.1 Server with Ops Center. I've uploaded the ISO image, updated the default profile and then I ran the plan. The installation stops at:
Xen: setup ISA identity maps
about to get started...
(XEN) traps.c:2458:d0 Domain attempted WRMSR 00000000c0010004 from 0x00008db490092100 to 0x000000000000abcd.
then nothing happens anymore.
If I use the ISO to install it without OPS Center everything works fine.
