xen discuss - Dec 2007 - How to enable 64bit solaris guest on top of solaris dom0

I can enabling 32bit solaris guest on top of solaris dom0, but I don''t
know how to enable 64bit solaris guest on top of solaris dom0. what
configuration I need to modify?

If you have a 64bit capable processor, it will start up a 64bit Dom0 by 
default. You will then be able to install 64bit Paravirtualized domains 
or 32 bit Full virtualized domains. If you have a 32 bit processor you 
can only run 32bit guests.

There is work to get 64bit Fully virtualized guests working

I'm running on 64bit capable processor, so how I can install 64bit
Paravirtualized domains or 64bit Fully virtualized guests on it?


Thanks!

As this is a Solaris dom0 then it should have booted 64bit by default
(check with isalist and look for amd64). If so you will only be able to
run 64bitParavirtualized domains (so if you run virt-install it will
install a 64bit domain). You cannot currently run 64bit fully
virtualized guest

Solaris doesn''t install as 32-bit or 64-bit - it is a boot time
decision.
Even if you are running in 32-bit mode when you install a domU (or a dom0,
for that matter), the resulting domain will be capable of booting into
either 32-bit or 64-bit mode.

PV domains will boot into whichever mode dom0 is running.  This is a
limitation imposed by the Xen 3.0.4 hypervisor.

If your dom0 is booted into 32-bit mode, HVM domains must also be booted as
32-bit.

If your dom0 is booted into 64-bit mode, you can boot HVM domains as either
32-bit or 64-bit.  By default, Solaris will boot into 32-bit mode in an HVM
environment due to the way Xen reports CPU capabilities to GRUB.  If you
want to boot a 64-bit HVM domain, you will have to edit your menu.lst file.
Simply replace each ''$ISALIST'' with ''amd64'',
and you should be all set.

Nils

Nils,
Thank you very much for your feedback.
Boris.

Nils,
Do you mean I can boot up a 64-bit HVM Solaris by editing the menu.lst? I
installed a Solaris 10 U4 HVM and it''s installed as 32-bit by default.
Seems in menu.lst, there is no $ISALIST. I attached my menu.lst file. Could you
help to have a look and tell me any hints to boot into 64-bit mode?
Thanks a lot.

There's a bug in the current release where 64-bit support
is not correctly detected in Solaris on HVM. This is fixed in
the 3.1.2 bits.

You should able able to modify the menu.lst entry
by adding the amd64 entries in and boot a 64-bit
Solaris HVM domain.

Solaris determines host capabilities for 64-bit mode on boot.
But I should make it clear that it choses different kernels when it  
determines which one to use, specifying the direct path to the AMD64  
kernel would force it to boot the 64-bit kernel.

I believe the desired files are located in /platform/i86pc/amd64 just  
update the menu.lst with the exact path to the kernel and boot_archive.

James,
There is no "amd64" folder under my /plaftorm/i86pc/.

bash-3.00# ls /platform/i86pc/

BTW, what's Solaris version should I install as HVM? Is there any issue w/
specific Solaris version?

What is an expected Nevada Build for 3.1.2 bits ?

So I''ve been told, B80 or so.

Sorry about giving you the wrong path, I'm not on a Solaris box right  
now, what's in /platform, /platform/i86pc/boot and /platform/i86pc/ 
kernel (Are they directories?) the actual kernel should be called  
'unix' and you could run file on it to see what it was built against,  
but that's with Solaris 10, I haven't poked around with the kernel on  
Nevada, it might be contained completely in the boot_archive, doubt it  
though.  You should be able to specify kernel /path/to/unix directly.

As for Solaris 10, I'd go with the most current, being U4 08/07, but  
have U3 handy if things quirk.

Solaris 10 U4 HVM install works for sure.
Through my experience , Solaris  10 U3 HVM install would fail.
SNV (build < 68)  HVM install issues:-
http://bderzhavets.blogspot.com/2007/09/xen-3.html 
Per Nirmal Agarval :- bug is fixed starting with SNV build 68
 
 
This message posted from opensolaris.org

I am using Solaris 10 U4 08/07. Yes, there is a folder named
"/platform/i86pc/kernel". And there are two "unix", one
under "/platform/i86pc/kernel", another under
"/platform/i86pc/kernel/amd64". I think the first "unix" is
for 32-bit, the one under "amd64" folder is for 64-bit. So I tried to
boot the 64-bit kernel by adding "/platform/i86pc/kernel/amd64/unix"
to grub. But after Guest load kernel, it will panic and prompt "panic:
cannot open /platform/i86pc/kernel/amd64/unix".
When I boot from "/platform/i86pc/kernel/unix", Guest can boot into
32-bit mode successfullly.

Simple tests are ran to determine the correct kernel to boot, and in
this instance, the BIOS is telling the bootstrapper that it's only
capable of 32-bit mode, so it won't work with the 64-bit kernel as you
have reported. Could you tell me what kind of processor you have, the
BIOS revision/vendor, and the motherboard. On this mailinglist, others
have noted that HVM mode is not capable of booting into 64-bit mode in
some instances, this looks like the case.

I'm using a Quad-Core Intel(r) Xeon(r) 5300 Series machine. And I can boot
up 64-bit Windows HVM on it.

I just booted by S10u4 hvm domain in 64-bit... I edited the
grub menu.lst adding a 64-bit entry which said..

title 64-bit Solaris HVM
kernel /platform/i86pc/multiboot  /platform/i86pc/kernel/amd64/unix
module /platform/i86pc/boot_archive

However, I am running pre-release 3.1.2 based bits. So
if this doesn't work for you, it would be a bug in the
current bits.

I can't reproduce the issue, since I'm using an AMD Opteron, Sun  
Ultra-20 M2 (High-end config)  Tell me if it's fixed when B79 it out.   
Internally they're at ON B79, community is still B77, but you can BFU.

Hi,
   Anyone know where I can find the official released change list for
different release of Nevada so I can learn which new feature has been
added and which existed bug has been fixed? 




Thanks!
Frank

Hi,
   Anyone know how to run PV Guest on solaris dom0?  Using
"virt_install" or using "xm create xxxx.py"?  or both method
are OK?




Thanks!
Frank

For features, have a look at:
http://www.opensolaris.org/os/community/on/flag-days/

For bugfixes, you need the putback logs, see:
http://www.opensolaris.org/os/community/on/onnv_putback_logs/
or look at the relevant bugid.

Both will work. virt-install is generally recommended.

Where can I find the kernel for PV Guest? I want to boot PV with a
python file but there is no suitable kernel for PV Guest.

With a Solaris dom0 we use ''pygrub'' to read the kernel (and
boot
archive) from the root filesystem of the guest. For non-Solaris dom0,
where pygrub apparently doesn''t work, you have to extract the kernel
and boot archive from the filesystem image (CD, disk, etc.).

What dom0 are you using?  Depending on what dom0 and
version of Xen, the answer is different for the py
format.

In general, the Xen aware "unix" lives at
   /platform/i86xpv/kernel/[amd64]/unix

For a solaris dom0, and for modern Linuxes,  e.g. FC8,
the following should be sufficient for a py file since
we added support for auto-detecting the solaris kernel.

name = "solaris"
vcpus = 1
memory = "512"
root = "/dev/dsk/c0d0s0"
disk = [''file:/tank/guests/solaris/disk.img,0,w'']
vif = ['''']


If you have an older linux dom0, or want to boot a
cap-eye install kernel, you can use the following.

# pygrub path different between linux and Solaris dom0s
name = "solaris"
vcpus = 1
memory = "512"
bootloader = "/usr/lib/xen/bin/pygrub"
kernel = "/platform/i86xpv/kernel/amd64/unix"
ramdisk = "/platform/i86pc/amd64/boot_archive"
extra = "/platform/i86xpv/kernel/amd64/unix -k"
root = "/dev/dsk/c0d0s0"
disk = [''file:/tank/guests/solaris/disk.img,0,w'']
vif = ['''']



Thanks,

Thanks for your reply, Mark. I am running on a Solaris Dom0 and I can
boot up Solaris PV Guest with a py file as you mentioned.
