xen discuss - May 2008 - Multibooting OpenSolaris 2008/05 , SNV87, Linuxes on the same box ?

I have SNV87 installed on bare metal and multibooting wth several Linux
instances on
the same box. I''ve just placed Linux Grubs into their own disk
partitions (/boot or /root)
and modified /boot/grub/menu.lst on SNV87 instance correspondently.
I suspect that attempt to install OpenSolaris 2008/05 on same box will cause MBR
to be
overwritten by new loader. I would be glad to be wrong about that.

Yes, just like Solaris 10 and OpenSolaris BXX (All of them) it''ll 
clobber everything, it likes doing it.  Sun''s partitioner is still 
retarded and Caiman''s even worse, so yeah :-)

Expect it to break things, just reinstall from OpenSolaris B87.

please read the release note
snv87 and 100805 can not be multi-boot together, docs seems to indicate 
U can only choose  one.
200805 does Multi-boot with window, linux

I believe it''s actually to do with how Solaris2 partitions work.  You 
can only have one primary Solaris2 partition per disk that will boot, if 
he has multiple disks with one primary Solaris2 partition per disk, he 
should be able to make it work.

James,
I can afford one more SATA Drive :-)
I am not sure  that :-
1.  OpenSolaris 2008/05 Grub would understand 
additional entry referencing SNV78 instance on drive 0.
Currently there are 2 SATA drives installed ( disks 0,1).
2. When i''ll atach one more it''s going to be disk 2 and
OpenSolaris 2008/05
installer must recognize all 3 drives and understand that primary partition for
install
may be created only on disk 2.
Thanks.

(Open)Solaris grub has been modified for UFS support, and it does  
autoconfiguration, but you should try to see if using root (hdx,x)  
works, displaying type xy (Solaris UFS) if successful.  Explicitly  
telling each entry where to boot the kernel from will make it work,  
but as I''ve said you can''t boot multiple Solaris installs from
a
single disk, therefore three systems, three disks, and some grub entry  
modification and addition is needed.  If you like I''ll try with VMware
tonight and reply to this displaying my progress.  I have two sata  
disks, one pendrive, and one external usb disk, but I cannot use my  
secondary sata disk as this is my file archive, therefore I must test  
using virtualization.
