Xen devel - Jan 2010 - debian lenny 3.2.1 doesn''t boot, livexen boots just fine

Hi. I have series x3500 ibm server running xen 3.0.3 from etch. When trying to
use xen 3.2.1 from lenny, xen hangs without any messages just after grub2
starts booting the xen image.

When I tried livexen cd with xen 3.2.1 from lenny, it works just fine. The
only difference is probably that livexen uses grub legacy, while I have to use
grub2, because my root is on raid+lvm.

Also, current configuration doesn''t see all of the 6GB of ram, only the
first
3GB, even with pae xen installed, that''s why I''m trying to get
newer xen up.
However It might be problem with grub but I have no idea how to find out. 

I''d like to try to find out if I really can''t get newer xen
running before
I''ll have to try using kvm or something like that.

Could anyone point me in some useful direction?

thanks
Martin Kraus

Check out this (old) thread:
http://lists.xensource.com/archives/html/xen-users/2007-08/msg00028.html
This isn''t for grub2, and may not be related, but I had a similar
problem
with Fedora (still existed in Fedora 8, I believe it still exists in RHEL
5.3).  For me, the problem was only for xenified kernels.  Others had the
same issue with other distributions.  The recommended patch at that URL is
also listed or otherwise mentioned in the Fedora and RedHat bug tracking
systems.  I don''t know if grub has a bug tracking system or if the bug
has
ever been reported for it.  Assuming not, then perhaps it made its way into
grub2 as well.  That said, I don''t know if it would be possible to
manually
make the changes from that patch or not (because I don''t know if that
piece
of source still exists in grub 2), but figured I would mention it in case it
could help.  Calling this a grub bug, IMHO, isn''t necessarily accurate
even
though grub CAN fix it (seems to be related to the BIOS in use, and could be
a BIOS bug), but that isn''t to say that it definitely isn''t [a
grub bug]
either.

Hi!

 I have a tip for you:

1- Get the ISO of the Debian Lenny 5.0 amd64 from http://debian.org;
2- Install your Debian into your own partition scheme (LVM over RAID);
3- Reboot into your new fresh Debian Lenny; upgrade it;
4- * GRUB1 is still the default in Lenny, verify it;
5- Install the Xen with the command: "aptitude install
xen-linux-system-2.6.26-2-xen-amd64";
6- Reboot into you new dom0.

Cheers!
Thiago

BTW, install your dom0 root partition within a 5G lvm logical volume,
leaving free blocks for you domUs within your big VG.

For example LVM on top of RAID1 (two mirrored discs of 500G)  for Xen:

Disc SDA:
/dev/sda1 type MD with 256M
/dev/sda2 type MD with 500G

Disc SDB:
/dev/sdb1 type MD with 256M
/dev/sdb2 type MD with 500G

Raid Volumes:
/dev/md0 with sda1 and sdb2 type bootable raid1 on /boot
/dev/md1 with sda2 and sdb2 type LVM

LVM Volumes:
/dev/md1 as a physical lvm volume
vgcreate HyperVG01 /dev/md1
lvcreate -L 1G -n xenhost01-swap HyperVG01
lvcreate -L 5G -n xenhost01-root HyperVG01

 Of course, you probably will make this raid and LVM volumes during the
Debian installation...

 Doing this, you will have 495G of free space within HyperVG01 VG volume for
you domUs and a simple partition scheme at your discs.

 You /boot partition will me mirrored too! So you can install GRUB in your
/dev/sdb and make the system bootable when sda fail.

 I hope this big picture can help you!

Thiago

Hello,

The syntax is not the same in GRUB2 example :
"old" grub.cfg style :

menuentry "Debian GNU/Linux, with Linux xen" {
	insmod ext2
	set root=(hd0,1)
	search --no-floppy --fs-uuid --set 116c3b30-4586-4f25-b7c1-c0d5c5a5b003
	kernel	/xen.gz	dom0_mem=1536M
	module 	//vmlinuz-xen root=UUID=bc847804-e4d5-49d0-b6ff-998886cbf9b2 ro
noquiet
	module	//initrd-xen
}


"New" grub.cfg style :

menuentry "Debian GNU/Linux, with Linux xen 3.4.3-rc2" {
        insmod ext2
        set root=(hd0,1)
        search --no-floppy --fs-uuid --set
116c3b30-4586-4f25-b7c1-c0d5c5a5b003
        multiboot       /xen-3.4.gz /xen-3.4.gz noreboot dom0_mem=3072M
cpufreq=xen cpuidle
        module  /vmlinuz-2.6.31.4-xen /vmlinuz-2.6.31.4-xen
root=/dev/md0 ro  noquiet
        module  /initrd.img-2.6.31.4-xen  /initrd.img-2.6.31.4-xen
}

You have to use "multiboot" ... and module the new (?) syntax.

For "standard" kernels the syntax has not changed :

menuentry "Debian GNU/Linux, avec Linux 2.6.32" {
	insmod ext2
	set root=(hd0,1)
	search --no-floppy --fs-uuid --set 116c3b30-4586-4f25-b7c1-c0d5c5a5b003
	linux	//vmlinuz-2.6.32 root=UUID=bc847804-e4d5-49d0-b6ff-998886cbf9b2
ro  noquiet
	initrd	//initrd.img-2.6.32
}

Thanks for the effort but how does this solve the problem that xen
doesn''t
start? I''m already running virtual hosts on that machine and I
can''t rip
all of this apart just to get stuck with unbootable system again. 

What I need is to find out what the problem is and then start ripping stuff
apart. I''ve tried to compile xen myself, versions 3.2, 3.3, 3.4, hg
tip, all
get stuck at some time during xen boot. Until I''ve tried the live cd, I
thought that it''s some incompatibility with my hardware but since the
live cd is
debian lenny on iso and it works fine, I have to look for the part that causes
xen to freeze.

Since there is only bios, grub and xen running in turn before the machine
gets stuck I''d say that the problem is in one of these systems.

I''ll try to find out something about grub and then I''m going
after kvm before
I decide to scratch the whole machine.

but thanks for the effort

Hi Martin,

I am having the same problem ... ever since I installed grub2 I can not
get xen to boot. I was told it is possible but yet to see someone
writing it down how. Tried the "new" syntax, put dummy=dummy as first
cmd line argument, even compiled the root=/... in the kernel nothing works.

I just get Panic on CPU 0 ... and stuck dump.

I can not use lenny.... the e1000e driver is broken and unfortuntely I
have that chip on my board... (similar issue with 2.6.18 !!!)

There is absolutely something with grub2 and xen combination (not hardware).

I tried even uninstall grub2 and install grub-legacy but grub2 simply
stays in MBR.

tried with the legacy thing after installing
>grub setup (hd0) just hang ... next boot still have the grub2 screen
... really

Tried all sort of combination from the grub menu (grub2) nothing makes
xen boot up

Someone on this list suggested to try to capture all the boot up until
crash, with serial console, which I am planning to do as soon as I get a
serial cable (usb2serial)...

If you get this work please please post it !!! I will report if I make
any headway.

This happend to me with xen 3.4

that is weird. are you sure you installed grub-legacy correctly? removed grub2
packages and used grub-install to update mbr and update-grub to update
menu.lst?

I have complete output from bios to kernel to getty on serial console, but I
get stuck without any messages from xen. All I get is the grub message booting
xen image .... and that''s it.

I strongly feel that it is problem with grub2 which bothers me, because grub
legacy can''t boot from lvm and I''m using lvm everywhere
therefor I''d like to
use grub2. So far, I''m not having any problems anywhere except with
this
single server. I planned to build a few virtual servers, but since the problem
seem to be with machines that have more than 4GB ram, I''ll look into
kvm, if
it solves my problems.

But I''d love to solve this. There are bound to be people running the
same
setup and if it works for them than there is a way to do it:)

Well you can update the driver! Grab the latest from intel''s site..

Yeah, grub developers changed stuff for grub2 that broke things.

Remember you cannot use  USB serial adapter on the Xen server!! 
but you can use it on a laptop/desktop where you capture the boot messages.

Many people have gotten grub2+Xen to work for them.

Thanks for the tip ... I tried all those no change :

here what I have currently in gurb.cfg both recommendation is use the
file name twice and use dummy=dummy
......
menuentry "Test Xen 3.4.2 xen w/linux 2.6.31.6-xen" {
        insmod raid
        insmod mdraid
        insmod ext2
        set root=(md1)
        multiboot /boot/xen-3.4.2.gz /boot/xen-3.4.2.gz dummy=dummy
dom0_mem=512M
module /boot/vmlinuz-2.6.31.6-xen-2 /boot/vmlinuz-2.6.31.6-xen-2
dummy=dummy root=/dev/md1 ro
module /boot/initrd.img-2.6.31.6-xen-2 /boot/initrd.img-2.6.31.6-xen-2
}
menuentry "Test Xen 3.4.2 xen w/linux 2.6.18.8" {
        insmod raid
        insmod mdraid
        insmod ext2
        set root=(md1)
        multiboot /boot/xen-3.4.2.gz /boot/xen-3.4.2.gz dummy=dummy
dom0_mem=512M
module /boot/vmlinuz-2.6.18.8 /boot/vmlinuz-2.6.18.8 dummy=dummy
root=/dev/md1 ro
module /boot/initrd.img-2.6.18.8 /boot/initrd.img-2.6.18.8
}
........

I am trying both the newest patched kernel and the stuck kernel coming
with 3.4.2 source ... both compile without error (I pretty sure I got
the config right for xen). Actually I can boot the 2.6.31.6-xen-2 on
bare metal (strangely not the 2.6.18.8 !!)

But got the same error ... so I strongly believe that the xen-3.4.2.gz
part crashes already with grub2 ..

I tried several other combination from grub> prompt pretty much the same
 CPU 0 panic and the numbers after (sometime sligthly different dump )

I realized that my self. A simple USB-serial cables are not good enough,
since I need a null-modem cable or a null-modem adapter btw the
usb-serial and the serial port... that is why it is taking me a little
time to get the cable... the stuff cisco (or sun) provides is just
straight through serial cable which connect to their "console" port
(which obviously has the crossing internally)

I read that ... makes sense but do not yet have the
cable..

I did follow that but could not boot XEN anyways.

No, you don''t use both of them.

The problem is that grub2 destroys the *first* parameter, 
so if you add the filename twice, that already is the extra 
first parameter, so no need for dummy anymore.

Or then don''t add the filename, but use dummy.
You just need *one* extra parameter there, as the first parameter.

See the working example from here:
http://old.nabble.com/Strange-interaction-from-grub2-and-XEN-td26464067.html

We really need to see the full console output to say what''s wrong.

Ok.. Hmm.. weird crash. Try removing "sync_console console_to_ring"
from the xen options.

Does that make a difference?

No, it''ll be a 32-bit-specific issue though. I would recommend just
running
a 64-bit build of Xen, if the CPU supports 64-bit mode. It''ll be
something
to do with GRUB2 dumping the dom0 kernel and initrd higher in memory than
GRUB1, past the end of where 32-bit Xen is set up to be able to access.
Probably not a hard fix, although I have no GRUB2 installation to test with.

I''ve had this problem for a year now. The only xen version running is
3.0.3,
newer versions crash with this error message. I''ve seen few posts about
this
but no replies.

It might be related to grub2. I''ve tried grub2 from debian sid today
and even
xen 3.0.3 stopped working, I had to downgrade back to stable grub2 debian
version.

Sounds something interesting ... to try...
Could you give some pointers as to how to compile the hypervisor as
64-bit???

I currently have a 32-bit setup but the hardware (CPU/MB/RAMetc) is
64-bit capable and I could just run 32-bit domUs I wanted to run more
than a bare dom0 on the hardware for continutity ....  but I am kind of
free to try ANYTHING .... but I need to run stuff in Debian/32-bit ...

So can you tell me how to compile a 64-bit xen.gz on my current Debian
32-bit PAE setup??? (the host needs to be up for certain other things
although 24/7 is not an issue...)

And if this is helpful to figure this out I am willing to spend some
time to experiment ... to trying to make 32 bit built xen.gz  run with grub2

Let me know...

Gabor

Assuming you know how to download and build and install 32-bit Xen, what you
may be able to do is: cd xen; XEN_TARGET_ARCH=x86_64 make install

It depends if your 32-bit gcc can cross-compile to 64-bit target.

Hi Keir,

Appreciate your help ....

I assume you mean export XEN_TARGET_ARCH=x86_64 and then make install
... it seems to generate the same 32bit xen

Tried this but something is not really working installed the mulitlib
package as well.

> It depends if your 32-bit gcc can cross-compile to 64-bit target.
Something is not right on my system (or I lack the skill to figure out
cross-compiling):-)

Well, I went with an easier way.... installed Debian 64 bit hypervisor
from testing and that solved the problem ....

So the bug is only shows up with 32bit hypervisor....not with 64....
this is why some people could use GRUB2 (most people I guess goes 64bit
these days...).

Pasi, maybe the above is a good bit for your Wiki pages... would have
saved me almost 2 weeks tinkering (I tried all kinds of things before
asking the question here on the list).

Since this is my very first XEN project, I yet to create a domU :-)

Let me know if the consol output would be any help ... but I guess that
just shows normal boot..

If it pushes people to the 64-bit hypervisor then all the better. That is
what gets the lion''s share of the testing, and should have better
performance too. But I will help someone get 32-bit Xen working with GRUB2
if they are really stuck and are capable of applying, building and testing
my patches.

I already added a note of this to the wiki pages.

I think it''s worth fixing, many distros will start using GRUB2 sooner
or later..
Hopefully someone can test the patches.
