Sorry for my ignorance but....I''ve installed a debian lenny dom0 with a xen kernel, then I''ve configured two domX. I''ve noticed that there isn''t a kernel installed for these ones. I run aptitude to update packages, I''ve updatede the dom0 kernel but....the others? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi Mauro, normaly you''re installing kernel''s directly in dom0 and pass the values for kernel + initrd image over xen config parameters in DOM0 on of my xen configs look like this: # # Configuration file for the Xen instance ADlb01, created on # Tue Sep 9 15:31:15 2008. # # # Kernel + memory size # kernel = ''/boot/vmlinuz-2.6.26-1-xen-amd64'' ramdisk = ''/boot/initrd.img-2.6.26-1-xen-amd64'' extra = ''console=hvc0'' memory = ''2048'' vcpus = ''8'' # # Disk device(s). # root = ''/dev/sda1 ro'' disk = [ ''phy:system/ADlb01-disk,sda1,w'', ''phy:system/ADlb01-swap,sda2,w'' ] # # Hostname # name = ''ADlb01'' # # Networking # vif = [ ''bridge=xenbr0'' ] # # Behaviour # on_poweroff = ''destroy'' on_reboot = ''restart'' on_crash = ''restart'' In DomU your installing |only the "linux-modules-2.6.26-1-xen-amd64"-Package. This one is for 64Bit systems, there should also a 686 image around. If your installing a DOMU from scratch you could also use the xen-create-image scripts which is quite handy at some cases. | Mauro wrote:> Sorry for my ignorance but....I''ve installed a debian lenny dom0 with > a xen kernel, then I''ve configured two domX. > I''ve noticed that there isn''t a kernel installed for these ones. > I run aptitude to update packages, I''ve updatede the dom0 kernel > but....the others? > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I have to upgrade only the linux-modules in domX? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi Mauro, yes that''s true for example my /boot direktory in domU looks like this blubba:/boot# ls -al /boot/ insgesamt 1260 drwxr-xr-x 2 root root 4096 6. Apr 20:25 . drwxr-xr-x 23 root root 4096 6.

Mär 22:20 System.map-2.6.26-1-xen-amd64 If only installed the linux-modules for the configured kernel in the xen config in dom0 blubba:/boot# aptitude search linux-modules* p linux-modules-2.6-xen-amd64 - Linux 2.6 modules on AMD64 v linux-modules-2.6.26-1-amd64 - v linux-modules-2.6.26-1-openvz-amd64 - v linux-modules-2.6.26-1-vserver-amd64 - i linux-modules-2.6.26-1-xen-amd64 - Linux 2.6.26 modules on AMD64 p linux-modules-xen-amd64 - Linux modules on AMD64 Hope that helps.

Mär 22:20 System.map-2.6.26-1-xen-amd64Do you really mean DomU? The kernels are read from Dom0. If you want to read it from DomU you need pvgrub or pygrub. I usually copy the kernel/initrd for DomUs into some other dir (f.e. /boot/domU-kernels - don''t forget to change your xen-DomU.cfg) or switch to pvgrub. If you use the same kernel/initrd-file for Dom0 and DomU, then you have to update (at least your modules) in DomU, too.

Hi Fabian, yes I mean DomU, as you said > The kernels are read from Dom0. so there is no need to install the kernel package in domU the linux-modules package is enought. To configure Dom0 and DomU kernel I did the following steps and they worked for me. in Dom0 I installed linux-image-2.6.26-2-xen-amd64 package then I put this 2 values in xen-domU.config file for example: kernel = ''/boot/vmlinuz-2.6.26-2-xen-amd64'' ramdisk = ''/boot/initrd.img-2.6.26-2-xen-amd64'' next i installed the linux-modules package in domU. Thats all.
