All, Platform : Toshiba Tecra M5 OS: OpenSolaris 2009.06 I setup the configuration using http://www.opensolaris.org/os/community/xen/docs/2008_11_dom0/ In addition (prior to creating the alternate be), I extracted the acpi.tar (known issues for Toshiba Tecra M5) On reboot (using xvm), I get v3.1.4-xvm ....... SunOS Release 5.11 Version snv_111b 64 -bit Copyright.... Use is subject .... <hang> Q) how do I enable further debug messages to see where the hang is ? - is there a grub flag ? Any suggestions if I followed the steps incorrectly ----------------------- sundeep@sundeep:~$ cat /rpool/boot/grub/menu.lst splashimage /boot/grub/splash.xpm.gz background 215ECA timeout 30 default 3 #---------- ADDED BY BOOTADM - DO NOT EDIT ---------- title OpenSolaris 2009.06 findroot (pool_rpool,1,a) bootfs rpool/ROOT/opensolaris splashimage /boot/solaris.xpm foreground d25f00 background 115d93 kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS,console=graphics module$ /platform/i86pc/$ISADIR/boot_archive #---------------------END BOOTADM-------------------- title Windows rootnoverify (hd0,0) chainloader +1 # Unknown partition of type 15 found on /dev/rdsk/c7d0p0 partition: 3 # It maps to the GRUB device: (hd0,2) . title opensolaris-1 findroot (pool_rpool,1,a) bootfs rpool/ROOT/opensolaris-1 splashimage /boot/solaris.xpm foreground d25f00 background 115d93 kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS,console=graphics module$ /platform/i86pc/$ISADIR/boot_archive #============ End of LIBBE entry ============title xvm findroot (pool_rpool,1,a) bootfs rpool/ROOT/xvm kernel$ /boot/$ISADIR/xen.gz module$ /platform/i86xpv/kernel/$ISADIR/unix /platform/i86xpv/kernel/$ISADIR/unix -B $ZFS-BOOTFS,console=text module$ /platform/i86pc/$ISADIR/boot_archive #============ End of LIBBE entry ============ thanks sundeep
