Hi Dave, As a part of efforts to get some debug information about the hanging issues with Intel vt-d in the developing xvm bits, I tried to boot xvm onnv_89 on the NHM-EP sample box in my lab. After brand new installation of Nevada build 89, I tried to boot xvm by selecting the xvm item from grub menu. XVM domain 0 boot failed with the following displayed: SunOS Release 5.11 version snv_89 64bit Copyright 1983-2008 Sun Microsystem, Inc. All rights reserved Use is subject to license terms (Can''t load TOD module) Press any key to reboot After pressing space key, the system rebooted. Is this a known issue and there exists any workaround? Thanks, -allen
