I suppose the good thing is that it happened on a VM guest that is not critical, so I don't have to experiment with the host that has four important guests running on it. >>> >>> Any ideas? >>> >>> Emmett >> I saw this problem on one machine I upgraded from 6.3 to 6.4 recently. >> When I boot it in verbose mode I see the following messages: >> >> dracut: /proc/misc: No entry for device-mapper found >> dracut: Failure to communicate with kernel device-mapper driver >> >> which led me to the following bug report: >> >> http://bugs.centos.org/view.php?id=6304 >> >> Just today kernel 2.6.32-358.2.1 became available.

Try this command where the kernel is installed and not booting (when booted into a kernel that works): lsinitrd /boot/initramfs-2.6.32-358.2.1.el6.x86_64.img | grep dm-mod (if you have one of the other 358 kernels installed, use that version instead of2.6.32-358.2.1.el6.x86_64 ) -------------- next part -------------- A non-text attachment was scrubbed...
