RHEL Clones (Centos, Scientific, CERN) network installation on XenServer 6.2
when I tried to install I had the same problem. using the procedure in xenserver (cli)
xe vm-list
get uuid of your vm
xe vm-param-set uuid=uuid_of_your_virtual_machine platform:viridian=false
I could continue the installation.
We had this problem as well. You need to use text mode, or disable/downshift the graphical install during the netboot. On your kernel options pass nohz=off highres=off See: https://bugzilla.redhat.com/show_bug.cgi?id=632811
