Re: [Xen-users] How to change the default kernel of Guest_OS
 
By the way, *DO NOT* use "rpm -U" for kernels, because any error can screw up your ability to reboot successfully. Always use "rpm -i" for kernels.

If you're using pygrub, you need to edit /boot/grub/grub.conf in the DomU.
  
 Hello Everyone,
  
Domain-0 OS:Centos5[final] Guest OS: Centos5[Centos5[final]
  
The virtualization [para] set up was working fine until I have done a kernel upgrade from 2.6.18-8 to 2.6.18-8.1.8 at the guest OS level. 
 My dom-0 is still working fine with the updated kernel. I used the same update package and -Uvh at my guest OS level and I changed the default 
kernel-2.6.18-8.1.8.el5xen to kernel-2.6.18-8.1.8.el5 in Guest's grub.conf [Before the Kernel update, I had only one (xen)Kernel at Guest_OS]
  then
  
xm reboot cenos5v [Didn't came up]
  
then tried 
  # xm create /etc/xen/cenos5v 
 Using config file "/etc/xen/cenos5v". 
Going to boot CentOS (2.6.18-8.1.8.el5)   kernel: /vmlinuz-2.6.18-8.1.8.el5 
  initrd: /initrd-2.6.18-8.1.8.el5.img Error: (22, 'Invalid argument') 
  Querry:
  
How do I change my guest's default bootable kernel back to xen-kernel.
  Please help me out and your suggestion would be appreciated.
 
  Thank you All
