This issue has been posted before, but no clear solution, i am sending again. 2.6.32 pvops dom0 booted with xen 4.0. However the xend can not start. I believe that is something related to the *evtchn*. I compile the CONFIG_XEN_DEV_EVTCHN=y in kernel, so i donot need to load it. When the dom0 booted, I can see there is a entry for evtchn in /dev/xen along with gntdev. But when xend starts, the evtchn in /dev/xen disappeared. and xend is not properly started. The error log in /var/log/xen/xend.log is the following: [2010-06-18 10:51:35 4685] INFO (SrvDaemon:332) Xend Daemon started [2010-06-18 10:51:35 4685] INFO (SrvDaemon:336) Xend changeset: unavailable. [2010-06-18 10:51:35 4685] ERROR (SrvDaemon:349) Exception starting xend ((111, ''Connection refused'')) I am using a centos 5, which has an old udev. I tried to modified the udev rules in /etc/udev/rules.d/xen-backend. rules and changed evtchn to xen-evtchn. No luck. Any ideas?

We added a patch that would change the name to ''xen/evtchn'' instead of ''evtchn''. (git commit 376d908f52427591cef4acd172db9c3ef28676ec) I am not really sure what corresponding change in userspace goes with it.. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
