How are you booting the xen domU's, with pygrub, pvgrub, or with external kernel? Smells like either the mkinitrd failed to run at all, or ran in such a way that it didn't put some required xen block device into the ramdisk.
For that matter--what hypervisor host are you using for the SL6 xen domU's--is it an SL6 guest on an SL5 hypervisor? I thought SL6 didn't
support being a xen host anymore. Steve Timm On Tue, 14 Jun 2011, Stephan Wiesand wrote:

It seemed all of my 5 Xen DomUs running SL6 failed to boot upon rebooting. It looks like all of these systems failed at roughly where switchroot is called. Interestingly, I could recover from this by shutting down the DomU, mounting then chrooting the DomUs filesystem and issuing: # rpm -ivh --force kernel-2.6.32-131.2.1.el6.x86_64.rpm Not sure how widespread this issue is, but I had a 100% failure rate on Xen DomUs. The one bare metal system I updated did so with no errors.no problems here on the two Xen domUs we're currently running. But then, we're still updating kernels with "rpm -i" rather than yum. Just a data point. Regards, Stephan
