[Xen-users] Troubleshooting Xen 4.0 + 2.6.32.16 pv_ops install
Hi, I have several servers Supermicro - running Xen 3.4.1 @ debian 5.0 x64 running without any issues for more than year. Now I bought new server with exactly same config and installed Ubuntu 10.04 x64 - Xen 4.0.1-rc4 - 2.6.32.16 pv_ops - base Ubuntu 10.04 install boot without issues - Xen 4.0.1-rc4 compiled and installed withou any problems - 2.6.32.16 pv_ops dom0 kernel with custom config. That config has Boris verified as working here in mailing list. Also me mysel booted this kernel config correctly in vmware machine with mirror sw configuration. I tried to boot dom0 kernels: - from older machines 2.6.18.8 - Debian 2.6.32 backports with same result - reboot after Xen 4.0.1 Boot process: Xen 4.0.1 part boots OK afterward processing dom0 kernel get machine to hard reset. I dont see anything on screen. The machine is remote - i have supermicro KVM console connection. There is option for serial console output. Please can you point me how to troubleshoot this ?

Re: [Xen-users] Troubleshooting Xen 4.0 + 2.6.32.16 pv_ops install
Little progress.
I took .config from Ubuntu 10.04 server headers and compiled jeremy
git kernel with it.
Obviously its almost full kernel config enabled.
I tried to boot xen with it - I can see the output - but it ends with panic.
Please see enclosed screenshot.
Grub entry looks like this:
menuentry "Xen 4.0.1-rc4-pre / Ubuntu 10.4 kernel 2.6.32.16 pvops" {
insmod ext2
set root=''(hd0,1)''
multiboot (hd0,1)/xen-4.0.1-rc4-pre.gz dom0_mem=1024M dummy=dummy
com1=115200,8n1 console=com1,tty,vga com1=115200,8n1
module (hd0,1)/vmlinuz-2.6.32.16 dummy=dummy root=/dev/sda1 ro nopat
console=tty0 console=ttyS0,115200n8
}
But still cant get serial output, but at least I can see error on the
screen outpu.
Any idea?

Re: [Xen-users] Troubleshooting Xen 4.0 + 2.6.32.16 pv_ops install
I gave up on Ubuntu 10.04 and tried Debian 5.0 x64.
Still using 4.0.1-rc4 and jeremy git kernel 2.6.32.16
Things little changed:
1) I can succesfully boot xenified 2.6.18.8 dom0 kernel!
2) 2.6.32.16 pv_ops kernel boot stops at point
"Write protecting the kernel read-only data: 7224k"
Than machinge reboots
Grub entry:
title Xen 4.0, Linux kernel 2.6.32.16
root (hd0,0)
kernel /xen-4.0.gz dom0_mem=1024M loglvl=all guest_loglvl=all
module /vmlinuz-2.6.32.16 root=/dev/sda2 ro nomodeset
title Xen 4.0, Linux kernel 2.6.18.8

kernel /xen-4.0.gz dom0_mem=1024M loglvl=all guest_loglvl=all
module /vmlinuz-2.6.18.8-xen0 root=/dev/sda2 ro nomodeset
Kernel config included.

Re: [Xen-users] Troubleshooting Xen 4.0 + 2.6.32.16 pv_ops install
OK so here is my result: Mainboad Supemicro X8DTT-F http://www.supermicro.com/products/motherboard/QPI/5500/X8DTT-F.cfm CPU Xeon X5650 Debian 5.0 x64 Xen 4.0.1-rc4 x64 Kernels: 1) xenified 2.6.18.8 dom0 --- OK 2) xen + pv_ops 2.6.31.13 dom0 --- OK 3) xen + pv_ops 2.6.32.16 dom0 --- stops booting at "Write protecting the kernel read-only data: 7224k" 4) pv_ops 2.6.32.16 same kernel as 3) --- baremetal boots OK 5) xen + pv_ops 2.6.32.16 dom0 in VMware VM on different machine --- OK 6) xen + 2.6.34 dom0 from brand new OpenSUSE 11.3 --- OK 7) 2.6.33.x pv_ops - compile errors My motherborad has lastest BIOS, several tests done with different BIOS and kernel configs. So my conclusion is that there is something wrong in combination Xen 4.0.1-rc4 + 2.6.32.16 pv_ops + X8DTT-F Since 2.6.32 pv_ops kernel should be "long term support" I would like to use this one, but currently its not working for me. If anybody has idea how to troubleshoot / make it working - please give me.

Maybe Matching Threads
- 2.6.32.16 - pv_ops kernel compile error
- 2.6.31 xenified kernel - not ready for production
- Blktap-control under 2.6.32.16-1.2.108.xendom0.fc13.x86_64
- Serial logs for 2.6.31 (commit 12e8537b6b29807cb9e13d728b2e5bab40424df7) under Xen Unstable on top of Ubuntu 9.04 Server
- XEN 4.0.1 + pv_ops Kernel + CentOS 5.5 x86_64, is there an easier way.
