Enabling serial console

With OpenSolaris b126 or later, svcadm enable milestone/xvm will use the current console settings in Solaris. On older releases, see the instructions below.

By default, the hypervisor will not use a serial console itself. To enable it (allowing debugging information and access), you will need to modify /boot/grub/menu.lst as follows. If your serial console is on ttya in Solaris (check eeprom if you're not sure), then add an entry similar to the following:

    title Solaris xVM with serial console
    kernel$ /boot/$ISADIR/xen.gz console=com1 com1=auto
    module$ /platform/i86xpv/kernel/$ISADIR/unix /platform/i86xpv/kernel/$ISADIR/unix
    module$ /platform/i86pc/$ISADIR/boot_archive

If the console is on ttyb in Solaris, then use com2 appropriately.

See 6593895 install does not set Xen console settings.
