Hello guys, Soem time after, I''m trying XEN again, now using Fedora Core 4 on Dell Power Edge 2850 with ALL updates and XEN installed via RPM. The kernel freeze while booting with messages: ... Checking ''hlt'' instruction.... OK. ExtINT not setup in hardware but reported by MP table ENABLING IO-APIC IRQs Brought up 1 CPUs migration_cost=0 cheking if image is initramfs... it is Freeing initrd memory: 4274k freed Grant table initialized NET: Registred protocol family 16 PCI: Using configuration type 1 And "freeze" here.

I''ve searched and tried a lot of things (until now, without sucess): .......................................................................... "Try putting ''usb-handoff'' on the *linux* command line. If that doesnt work, try ''nousb''." "I also had to boot with ''noirqbalance'' in the kernel command line." "Adding "noreboot" to the kernel comandline (in the line with the xen hypervisor, not the dom0 line) might also help." "Booting xen with "ignorebiostables" seems to solve the problem." ..........................................................................

Neat toys installed :) There''s a few things there that could be the culprit, I''ve never encountered your error, but never xenned a system that had DRAC installed. Does the DRAC function after getting Xen Linux to finally boot? Not entirely sure, but seems to me whatever is not working now was the culprit. If everything is working after ignorebiostables was added, this tells me the drac or raid bios was (probably) the issue, i''d venture to further speculate and narrow it down to the drac. Can you post back with more data on what''s working now and what is not, or if all devices are working after adding ignorebiostables to boot paramaters?

Did a little research for you, found some references to the same thing (example is debian but its the same problem) http://lists.debian.org/debian-amd64/2006/06/msg00166.html Looks like you may have an architecture mis-match between your kernel, modules, or modprobe itself. One is 64, one is 32 .. and one may be 64 or 32 (word size). Anyway, they all need to match. So I''d check to be sure the initrd is up to date, and double check that you installed the correct version of Xen wrt your OS. I think at this point you''d save time by just wiping and starting over :) Hope this helps. Best, -Tim On Wed, 2006-10-18 at 16:57 -0300, Tiago Cruz wrote:> Hello guys...

RE: [Xen-users] Kernel Freeze - Xen 3.0.3 - Solved! (README)
Hello guys!!! :-)
For the list''s historic: If you have got a Dell PowerEgde 2850, or
another MegaRAID controller based system running on LVM and have had a
problem like this before, please have a glimpse on it.
By the list''s guys help, we have faced two problems (thanks for Tim,
Badiane, Brian, ...)
- The xen-3.0.3 packages for Fedora Core 5 is only for a i386, and not
for the x64 one so that you need to compile it yourself (Note: I''ve
tested packages of Fedora on my virtual machine - but in a i386 and
without a RAID it works very well!)
- The MegaRAID is not supported by the of xen 3.0.3''s default kernel.
So, we have to compile it for a x64 adding support for the MegaRAID on
kernel as well as for the initrd file (just on kernel it did not work
for me):
The steps are as follow:
1-) Install all the dependencies (they might not be all listed in the
README file)
gcc python-devel.x86_64 zlib-devel.x86_64 ncurses-devel.x86_64
libgcrypt-devel.x86_64 openssl-devel.x86_64 strace patch
2-) Compile the kernel (I''m not sure how I did this exactly :( )
# wget
http://bits.xensource.com/oss-xen/release/3.0.3-0/src.tgz/xen-3.0.3_0-src.tgz
# cd xen-3.0.3_0-src
# make KERNELS="linux-2.6-xen0 linux-2.6-xenU"
# make linux-2.6-xen-config CONFIGMODE=menuconfig
Edit the .config file (again I''m not sure of which kernel I had to
edit,
so, I''ve edited either :)
[root@xen xen-3.0.3_0-src]# grep MEGARAID linux-2.6.16.29-xen/.config
CONFIG_MEGARAID_NEWGEN=y
CONFIG_MEGARAID_MM=y
CONFIG_MEGARAID_MAILBOX=y
CONFIG_MEGARAID_LEGACY=y
CONFIG_MEGARAID_SAS=y
[root@xen xen-3.0.3_0-src]# grep MEGARAID linux-2.6.16.29-xen0/.config
CONFIG_MEGARAID_NEWGEN=y
CONFIG_MEGARAID_MM=y
CONFIG_MEGARAID_MAILBOX=y
CONFIG_MEGARAID_LEGACY=y
CONFIG_MEGARAID_SAS=y
# make kernels
# make install
Then make sure that your new kernel has been edited in the GRUB file. Then boot
the system.
Even doing that it still did not work well but a least the following
ERROR stopped to come out. (yeahhh weĺl get there folks :)
"request_module: runaway loop modprobe binfmt-464c"
Then as life is not always easy this ERROR came back!!! :(
"VFS: Cannot open root device "VolGroup00/LogVol00" on
unknown-block(0,0)"
Even having the ext2/3, reiserfs and megaraid built-in on my kernel!
3-) Make your new initrd as following.
# cd /boot
# mkinitrd -v -f --with=megaraid_mbox --with=megaraid_mm initrd-2.6.16.29-xen
2.6.16.29-xen
Right!! Put it in your GRUB then do your test and good luck! :-)
=================================================================================title

Even doing that it still did not work well but a least the following
ERROR stopped to come out. (yeahhh weĺl get there folks :)
"request_module: runaway loop modprobe binfmt-464c"
Then as life is not always easy this ERROR came back!!! :(
"VFS: Cannot open root device "VolGroup00/LogVol00" on
unknown-block(0,0)"
Even having the ext2/3, reiserfs and megaraid built-in on my kernel!
3-) Make your new initrd as following.
# cd /boot
# mkinitrd -v -f --with=megaraid_mbox --with=megaraid_mm
initrd-2.6.16.29-xen 2.6.16.29-xen
Right!! Put it in your GRUB then do your test and good luck! :-)
