  • Thread-topic: [Xen-users] Building and Installing Xen 4.3 in Fedora11

Everything has done successfully but when I boot the kernel with xen  it will 
restart the system  after loading some xen modules without giving any error 
what could be the problem. Also i found some issue with manual grub entry at 
the end of the whole process. where we specify the boot partition 
root=/dev/mapper/VolGroup01/vg_fedora11 ro 
I don't find the vg_fedora11 on the given path.
Is it compulsory to have logical volumes like VolGroup01 to boot xen?? 

The path to your root device looks wrong to me.  On my systems /dev/mapper 
contains devices <vgname>-<lvname>, these are also available as 
/dev/<vgname>/<lvname>.  What you have above seems to be a combination of the 
two, although it could be Fedora generates the device names according to 
different rules than my system.  Perhaps what you need is 
/dev/vg_fedora11/roolv which I think are the default names from the FC11 
install.  If you get a shell during the boot you should be able to poke around 
under /dev to find the appropriate name.  Volume Group and Logical Volume names 
are arbitrary with no forced convention on naming.

If the system restarts too quickly to read the console you'll probably need to 
capture the output via a serial console.  You could also try the noreboot xen 
parameter (http://wiki.xensource.com/xenwiki/XenBooting).
