[Xen-users] Kernel DomU 2.6.36.1 dont boot PVonHVM
Hi all, I try to use kernel 2.6.36.1 in HVM but building the drivers xen-blkfront, xenfs, platform-pci. I used Xen 4.0.2-rc1-pre and a DomU is a ubuntu 10.04 and I try with ubuntu 10.10. In boot I receive error "Cannot find a root partition /dev/xvda2" and a prompt (initramfs) appear. In dmesg (initramfs) appear: blkfront: xvda: barriers enabled (tag) xvda: xvda1 vbd vbd-51712: 16 xlvbd_add at /local/domain/0/backend/vbd/470/51712 I try to create n initramfs, with any modules and the DomU dont boot. I forgot something? Can someone help me?

Re: [Xen-users] Kernel DomU 2.6.36.1 dont boot PVonHVM
Hi! All my Ubuntu 10.04 servers are using the Linux 2.6.36 compiled by me. Basically you should do: aptitude install build-essential libncurses5-dev wget -c http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.36.1.tar.bz2 tar xf linux-2.6.36.1.tar.bz2 cd linux-2.6.36.1 make defconfig make menuconfig Enable Xen within the menuconfig... make make deb-pkg dpkg -i ../linux-image*.deb depmod 2.6.36.1 update-initramfs -c -k 2.6.36.1 update-grub reboot PS.: You must use the GRUB1 if your dom0 is a XenServer or some old version of Xen... Hope to help! Cheers!

Re: [Xen-users] Kernel DomU 2.6.36.1 dont boot PVonHVM
Hi Martinx, thanks for you help. How you create DomU.cfg ? Especially disks? My DomU.cfg, in disks: disk=[ ''tap2:tapdisk:aio:/PATH/ubuntu10-04/hda.img,hda,w'' , ''tap2:tapdisk:aio:/PATH/ubuntu10-04/xvda.img,xvda,w'' ] In hda.img I have a /boot and in xvda.img I have swap and root (xvda1 is swap and xvda2 is / ).

Hi Boris, My root partition is /dev/xvda2, in kernel not PVonHVM my root partition is /dev/sda2 and a swap is /dev/sda1. Looks like this kernel not found the second partition (the root partition). This kernel "jump" the swap partition?? Thanks for you help.

Re: [Xen-users] Kernel DomU 2.6.36.1 dont boot PVonHVM
Hi Boris,
I try mount my root partition in /dev/xvda1 and I receive a new error:
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or directory
Target filesystem doesn''t have /sbin/init
No init found. Try passing init= bootarg
(initramfs)
I used a raw disk in my Xen, and this disks have a partition table create
when I installed a HVM VM.
This machine boot with my old kernel 2.6.32 with a pvdrivers (used this
patch: http://blog.alex.org.uk/tag/xen/ ).
I created a VM with this parameters for disk:
''tap2:tapdisk:aio:/PATH/ubuntu10.04/hda,hda,w'' ,
''tap2:tapdisk:aio:/PATH/ubuntu10.04/xvda,xvda,w'',
This is a xml dump (virsh dumpxml VM):
<disk type=''file'' device=''disk''>
<driver name=''tap''
type=''tapdisk''/>
<source file=''aio:/PATH/ubuntu10.04/hda''/>
<target dev=''hda'' bus=''ide''/>
</disk>
<disk type=''file'' device=''disk''>
<driver name=''tap''
type=''tapdisk''/>
<source file=''aio:/PATH/ubuntu10.04/xvda''/>
<target dev=''xvda'' bus=''xen''/>
</disk>
In hda I have my /boot, and xvda I have my / (root partition).
Anyone have any idea?
Cheers,
Roberto Scudeller

Re:[Xen-devel] Re: [Xen-users] Kernel DomU 2.6.36.1 dont boot PVonHVM
Recently, I just use the pvdriver patch of Alex for ubuntu 10.04 2.6.32, but in
my opinion, that patch is not generic for all kinks of kernel version, so, if
you want to use pvdriver on the target kernel version, you should compile it
& debug it on the target kernel version platform, this is a final solution.
so now, I'm studying the debug method on xen use gdbsx.
good luck.

Hi all again,
I try other kernel and the problem continues.
My DomU.cfg:
name='ubuntu10.04'
memory=512
vcpus=2
disk=[ 'tap2:tapdisk:aio:/PATH/ubuntu10.04/hda,hda,w',
'tap2:tapdisk:aio:/PATH/ubuntu10.04/xvda,xvda,w', ]
boot='c'
on_reboot='restart'
on_shutdown='destroy'
on_crash='destroy'
With the old kernel, 2.6.32.24, with pvdrivers (used this
patch:http://blog.alex.org.uk/tag/xen/ ) this VM boot OK.
I try kernels 2.6.36.1 and 2.6.37-rc4, and the problem continues:
blkfront: xvda: barriers enabled (tag)
xvda: xvda1
vbd vbd-51712: 16 xlvbd_add at /local/domain/0/backend/vbd/470/51712
Build the new kernel does not seem to be able to view all disk partitions in
xvda disk (I have / on xvda1 and swap on xvda2) with raw disks (sparse). I try
vhd disks and problem continues. These disks contains the partition table. The
xen-blkfronthave a problem with the disks right?
Could someone give me some more help?

Hi Boris,
I try mount my root partition in /dev/xvda1 and I receive a new error:
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or directory
Target filesystem doesn't have /sbin/init
No init found. Try passing init= bootarg
(initramfs)
I used a raw disk in my Xen, and this disks have a partition table create when I
installed a HVM VM.
This machine boot with my old kernel 2.6.32 with a pvdrivers (used this
patch:http://blog.alex.org.uk/tag/xen/ ).
I created a VM with this parameters for disk:
'tap2:tapdisk:aio:/PATH/ubuntu10.04/hda,hda,w' ,
'tap2:tapdisk:aio:/PATH/ubuntu10.04/xvda,xvda,w',
This is a xml dump (virsh dumpxml VM):
<disk type='file' device='disk'>
<driver name='tap' type='tapdisk'/>
<source file='aio:/PATH/ubuntu10.04/hda'/>
<target dev='hda' bus='ide'/>
</disk>
<disk type='file' device='disk'>
<driver name='tap' type='tapdisk'/>
<source file='aio:/PATH/ubuntu10.04/xvda'/>
<target dev='xvda' bus='xen'/>
</disk>
In hda I have my /boot, and xvda I have my / (root partition).
Anyone have any idea?
Cheers,

I would try repartitioning with "/" on /dev/xvda1

Hi Boris,
My root partition is /dev/xvda2, in kernel not PVonHVM my root partition is
/dev/sda2 and a swap is /dev/sda1.
Looks like this kernel not found the second partition (the root partition).
This kernel "jump" the swap partition??
Thanks for you help.
Cheers,
Roberto

Looks like your root partition is /dev/xvda1
Boris.

Hi all,
I try to use kernel 2.6.36.1 in HVM but building the drivers xen-blkfront,
xenfs, platform-pci. I used Xen 4.0.2-rc1-pre and a DomU is a ubuntu 10.04 and I
try with ubuntu 10.10.
In boot I receive error "Cannot find a root partition /dev/xvda2" and
a prompt (initramfs) appear.
In dmesg (initramfs) appear:
blkfront: xvda: barriers enabled (tag)
xvda: xvda1
vbd vbd-51712: 16 xlvbd_add at /local/domain/0/backend/vbd/470/51712
I try to create n initramfs, with any modules and the DomU dont boot.
I forgot something? Can someone help me?
Thanks for any help.
