Re: [Xen-devel] [Xen-users] xen on centos6.5 issue with /proc/xen

What does /etc/grub.conf look like?

Because the old kernel was custom, you might need to manually edit it to look similar to the entry in the instructions.

Hi 

   I followed this document to install Xen 

http://wiki.centos.org/QaWiki/Xen4

Xen package got installed :

rpm -qa |grep xen

xen-libs-4.2.4-33.el6.centos.alt.x86_64

xen-runtime-4.2.4-33.el6.centos.alt.x86_64

libvirt-daemon-driver-xen-0.10.2.8-7.el6.centos.alt.x86_64

centos-release-xen-6-2.el6.centos.x86_64

xen-licenses-4.2.4-33.el6.centos.alt.x86_64

xen-hypervisor-4.2.4-33.el6.centos.alt.x86_64

xen-4.2.4-33.el6.centos.alt.x86_64

and i rebooted to xen kernel (only had one entry in grub,before xen installation)

but after rebooting to new kernel its not showing anythig related to xen

xl info returns 

xl info

libxl: error: libxl.c:91:libxl_ctx_alloc: Is xenstore daemon running?

failed to stat /var/run/xenstored.pid: No such file or directory

cannot init xl context

there is not even  " /proc/xen "

What can be the issue.

Previous kernel was not standard kernel,it is a modified kernel from our service provider

Any idea why new kernel is not showing any xen bits

Thanks,
