ran routine updates on the lernel this morning and got this: WARNING: No module xenblk found for kernel 2.6.18-400.1.1.el5, continuing anyway The only references I can find are a year or so old. Anyone able to comment? or refer me? Have not rebooted. uname -a Linux bulkley.bvserver.ca 2.6.18-400.el5xen #1 SMP Thu Dec 4 13:29:23 EST 2014 x86_64 x86_64 x86_64 GNU/Linux Thanks, Dave -- "As long as politics is the shadow cast on society by big business, the attenuation of the shadow will not change the substance." -- John Dewey

But i guess the warning is from the normal, not xen enabled kernel. Does /boot/vmlinuz-2.6.18-400.1.1.el5xen exists? And is kernel-xen installed and the default kernel in the grub- config? regards Ulf

In CentOS 5 you must install kernel-xen for Xen dom0 or pv domu support.> uname -a > Linux bulkley.bvserver.ca 2.6.18-400.el5xen #1 SMP Thu Dec 4 13:29:23 > EST 2014 x86_64 x86_64 x86_64 GNU/LinuxThis is kernel-xen, note the "el5xen" in the name as opposed to "el5" in the one you installed above.

Also paste the output of this command from the affected domain: rpm -q kernel kernel-xen Peter

I converted a xen vm to kvm and got that error for the above reason. Bill
