similar to: Install of kernel-ml does not allow for usable /proc/xen

Here is something interesting... I went through the BIOS options and found that one R710 that *is* functioning only differed in that "Logical Processor"/Hyperthreading was *enabled* while the one that is *not* functioning had HT *disabled*. Enabled Logical Processor and the system starts without issue! I've rebooted 3 times now without issue. Dell R710 BIOS version 6.4.0 2x Intel(R)

Apologies: I installed the newer -26 kernel and had not rebooted into it. The grub2 menu item should have been "CentOS Linux (4.9.20-25.el7.x86_64) 7 (Core)". I am currently restarting that remote affected system (unmodified grub2 entry first).

Dave, Take a look at this kernel as it is the one I think we are going to release (or a slightly newer 4.9.2x from kernel.org LTS). This version has some newer settings that are more redhat/fedora/centos base kernel like WRT what is a module and what is built into the kernel, etc. https://people.centos.org/hughesjr/4.9.x/ Thanks, Johnny Hughes On 04/14/2017 05:16 AM, Anderson, Dave wrote: >

List moderator: feel free to delete my previous large message with attachments that's in the moderation queue...it's now obsolete anyway. I have found a fix/workaround for my reboot issues with Xen 4.6.3-12 + Kernel 4.9.13: Once I finally got serial output all the way through the boot process (xen+dom0) I discovered the stack trace: [Firmware Bug]: CPU7: APIC id mismatch. Firmware: 0

So, strangely, I have two _identical_ dualproc xeon mobos (same bios/ipmi versions, they even share an enclosure, one is right side, other is left), each with different cpu/memory: Using 4.9.13 with vcpu limited to 4, early in the boot process, the one that _was_ booting before setting the xen vcpu args says: "[ 7.060720] smpboot: Max logical packages: 2", and the other one says

Per request by toracat in: http://centos.org/modules/newbb/viewtopic.php?topic_id=13455&forum=37 comment #16, I would like to be able to add vnc alternative server setup info (vnc-lts-config and x11vnc) to http://wiki.centos.org/HowTos/VNC-Server, please. pjwelsh -------------- next part -------------- An HTML attachment was scrubbed...

There was a note that the non-Xen kernel at the same kernel version did indeed boot: "CentOS-6 4.9.20-26 kernel exhibits the same constant kernel-start-then-reboot issue when booting under the "CentOS Linux, with Xen hypervisor" grub2 menu option. However, it *does* properly boot under the "CentOS Linux (4.9.20-25.el7.x86_64) 7 (Core)" grub2 menu option!" Trying to

HI, We've started to see several issues with the Xen releases. Going back to basics I've used this guide https://wiki.centos.org/HowTos/Xen/Xen4QuickStart Once the install process is complete the grub.conf looks like this: default=0 timeout=5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title CentOS (3.18.21-17.el6.x86_64) root (hd0,0) kernel /boot/xen.gz

PJ, I didn't have virsh installed (libvirt-client).? After having installed it, it still didn't see the process: virsh autostart testvm error: failed to connect to the hypervisor error: no valid connection error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directory Then, after having installed libvirt, it gives essentially the same error.

We need a way to do two things to /usr/bin/grub-bootxen.sh in Xen4CentOS. 1. Automate running it if xen (the package) and the xen kernel are installed. But only if the user WANTS to run it. 2. Allow users to automatically modify the variables passed into the xen.gz line (that is, more or less memory, add console settings, etc.) If you look at the current script,

So far, I?ve only found information regarding blocking access for particular users. I want it the other way round, i. e. the whole maching usually not having access and allowing access to only a particular user. Allowing access

As a follow up I was able to test fresh install on Dell R710 and a Dell R620 with success on CentOS 7.3 without issue on the new kernel. My new plan will be to just move this C6 to one of the C7 I just created.

As libvirt from Xen is 1.3.0 and libvirt from CentOS 7.3 is now 2.0.0, libvirt from Xen has to be rebuild to upgrade the new libvirt 2.0.0 See my previous post : https://lists.centos.org/pipermail/centos-virt/2016-November/005255.html I've done it for my own repo : https://copr.fedorainfracloud.org/coprs/jmliger/virt7-upstream/ Regards, Jean-Marc Le 30/12/2016 ? 17:56, Francis The

Jiri Denemark has already proposed to help rebuild libvirt for CentOS-Xen but I don't know if he got all that is need to do so ? Maybe I could help also, but I would have to learn the Centos build system first.
