The mystery gets more interesting... I now have a CentOS 7.3 Dell R710 server doing the exact same thing of rebooting immediately after the Xen kernel load. Just to note this is a second system and not just the first system with an update. I hope I'm not introducing something odd. They only "interesting" thing I have done for historical reasons is to change the following

By default, /var/lib/xenstored is mounted tmpfs in centos 5 but this doesn't appear to be true for Xen4CentOS. This can cause performance issues as mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=446089 I'm not sure if this should be part of xencommons, but if not, adding a tmpfs mount should probably be documented on the quick start wiki page. Thanks, Sarah

Not sure about CentOS 6, but this was covered previously (at least for 7...not sure how much they differ)...not that I can find the message now, but here's what I recall/pieced together from bash history that works on CentOS 7: If the microcode you want is in the microcode_ctl package: mkdir -p /etc/microcode_ctl/ucode_with_caveats/ touch /etc/microcode_ctl/ucode_with_caveats/force yum

I think this may have been asked before, but what would it take to get debuginfo packages built for the Xen4CentOS kernels? If it's just a patch for kernel.spec file that nobody has gotten around to, what is the best starting place for making that patch? Thanks, Sarah

I experienced a bug that is likely the same as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1350373 . Commit b7dd0e350e0bd4c0fddcc9b8958342700b00b168 , which is supposed to fix it, doesn't appear in this kernel and doesn't apply cleanly either. Is there any point in trying to backport the patch? The backtrace is as follows: [ 32.304666] ------------[ cut here ]------------ [

It looks like no XSA-142 patch, which is "libxl fails to honour readonly flag on disks with qemu-xen" has been applied to Xen4CentOS. I assume this was on purpose? If not, I can have someone try adding the original patch from http://xenbits.xen.org/xsa/advisory-142.html and some variant of the commit from ef6cb76026628e26e3d1ae53c50ccde1c3c78b1b

I've seen this issue on about 15 different servers now. Anybody else seeing this? Screenshot: http://imgur.com/cBcwr8l I also have a video of the boot process if that will be helpful. -- Shaun Reitan -------------- next part -------------- An HTML attachment was scrubbed...

Hi, is there any guide for CPU microcode updates on CentOS6, Xen 4.10, kernel 4.9 ? Thanks Karel
