Re: [Xen-users] Brolen virtual machines after updates host system

["Galileon Galilei" <galileon@xxxxxxxxx>]

did you update the guest kernels as well? coz if you did, then they will need the new /lib/modules...

 

you can also update the host and leave the guest kernels alone...that way nothing has to be done for them

Do you have two kernels on your Xen-server, one for dom0 and one for domU? If you use your dom0 kernel also for your domU's, then ofcourse you need to copy the correct kernel modules to the virtual-servers' filesystems. If you have a seperate kernel for your domU's, and that one does not change, you don't need to update the virtual-servers in any way after doing updates on the dom0 kernel.

system


I upgraded the dom0 Kernel. And yes, it is modified (by openSuSE) for XEN.

My poblem is, that I need to have to modfiy the virtual guests ( i.e.
copy the correct kernel modules into their filesystems).
My question is, if there is any way to get around this (as we're plan to
use various instaces of XEN guests without touching them at every update)?

Thanks
