[Xen-users] WARNING:root:Unknown image directive recordfail

[Christian Mayorga <cmayorga@xxxxxxxxx>]

Dear All,

I am running a clean installation of xen 4.1 in ubuntu 12.04. I was able to run Xen Dom 0 succesfully but once I tryed to configure a VM I encounter problems. I am doing a VM installation on LVM. I had been able to install the OS in the VM partition but once I am tryng to start the VM start the problems. I am new in Xen I am not sure how to follow. I think the problem is on the booting of the VM as there were know issues with pygrub and grub which I was able to solve. Once I do @server02:/$ sudo /usr/bin/pygrub /dev/VolGroup00/VM01 I am getting the booting screen from grub but after it crashes and give the following output.


@server02:/$ sudo /usr/bin/pygrub /dev/VolGroup00/VM01
Using <class 'grub.GrubConf.

Grub2ConfigFile'> to parse /grub/grub.cfg

Below you will find all the details of the installation. Please feel free to ask any question or data to further troubleshoot and solve this problem.

Thanks,
Christian

Start the VM and connect to console (-c):

@server02:/$sudo xm create /etc/xen/VM01.cfg -c

In the installation process I choose to create Full LVM partition plus grub installation

Install the Ubuntu as VM

Set up the initial guest configuration and update it: /etc/xen/ubuntu.cfg

The important things are:
- Sector size   ->  512
- Start of the partition slice   ->  2048

Now fire up an calculator and multiply these number to get the correct offset:
512 * 2048 = 1048576

With this value you can already mount the partition.

christian@server02:/etc/xen$ sudo mount -o offset=1048576 /dev/VolGroup00/VM01 /xen

- Open the grub.cfg file (/grub/grub.cfg) in your favorite editor.
- Change msdos infos to a normal grub entry
- replace hd0,msdos1 -> hd0,0

Trying to create VM
