Re: [Xen-users] invalid kernel

["Mehmet Can ÖNAL" <mconalxen@xxxxxxxxx>]

first of all thanx for your answer.

xm info | grep xen_caps command gives me an output

xen_caps                             : xen-3.0-x86_32 hvm-3.0-x86_32

i have downloaded the kernel i tried to boot as domU from rhel site (rhn.redhat.com) as kernel-xen-2xxxx that its description says that this kernel enables vm operations. does that mean it's dom0 kernel?

would you mind explaining your answer a bit more that i'm so new to these concept

thanx a lot

Hello Mehmet,

i have installed xen 3.1 on rhel5 on IBM 3650 (32 bit). i tried to install rhel5 also as domU but i get an error while creating domU that

Error: (2, ';Invalid kernel', 'xc_dom_compat_check: guest type xen-3.0-x86_32p not supported by xen kernel, sorry\n')

is there something missing about my configuration or as the error says my guest kernel is not supported by xen 3.1? And does anybody know which rhel5 kernel should i use and where can i find it?

it looks like you're trying to boot a kernel that is not working with xen. I guess it's not a HVM domU, so my second guess is, that the kernel you try to boot does not support PAE.
you can check what kind of guest os you can boot with:

xm info |grep xen_caps

So, to resolve your problem, you either have to run your domU as a HVM machine, then you can use the rhel5 stock kernel (I think) or you have to get/build a PAE kernel.
