How to kickstart a guest with Centos 6.6 & Xen 4.4
by Elliot Fox 03 Aug '15

03 Aug '15

Hello, I posted a question over at xenproject.org but it was recommended that I send out a message here for help. My post there: http://www.xenproject.org/help/questions-and-answers/vanilla-pv-centos-gues… The TL;DR is: Everything I've found to kickstart a new vanilla rhel/centos guest points to specifying a kernel & and initrd- for RHEL/Centos 5. But where is the xen initrd for Centos 6? The Xen4Quickstart instructions are awesome, but after install you are left with a kernel and an initramfs & no initrd for a centos 6 guest in xen. So is there a better way to kickstart a fresh/vanilla VM post Xen4Quickstart instructions? Shall I build an initrd from the initramfs (and how) or is there another way? Apologies if this is discussed elsewhere, but if it is I have yet to find it and I've been looking around for some time. Thank you!

Timezone issues with migrations between host kernel 3.10 and 3.18
by Nathan March 30 Jul '15

30 Jul '15

Hi All, I'm seeing clock issues with live migrations on the latest kernel packages, migrating a VM from 3.10.68-11 to 3.18.17-13 results in the VM clock being off by 7 hours (I'm PST, so appears to be a timezone issue). This is also between xen versions, but rolling the target back to 3.10 resolved so don't believe the recent XSA's are related. Anyone else seen behavior like this or have any ideas on how to resolve? - Nathan

Re: [CentOS-virt] Where are the Centos 7.1 1503 KVM repos please?

Thanks for all the replies. Looking at the specs for the processor it does not seem to have the vmx features in /proc/cpuinfo: http://www.notebookcheck.net/Intel-Core-2-Duo-T6400-Notebook-Processor.3510… and the output from grep -E ‘vmx|svm’ /proc/cpuinfo is empty. /lib/modules/3.10.0-229.7.2.el7.x86_64/kernel/arch/x86/kvm [keith.roberts@acer-centos kvm]$ ls kvm-amd.ko kvm-intel.ko kvm.ko [keith.roberts@acer-centos kvm]$ [keith.roberts@acer-centos kvm]$ modprobe kvm-intel modprobe: ERROR: could not insert 'kvm_intel': Operation not permitted [keith.roberts@acer-centos kvm]$ lsmod | sort ... iwlwifi 112501 1 iwldvm jbd2 102940 1 ext4 kvm 461126 0 libahci 32009 1 ahci [keith.roberts@acer-centos kvm]$ modprobe kvm-amd modprobe: ERROR: could not insert 'kvm_amd': Operation not permitted [keith.roberts@acer-centos kvm]$ modprobe kvm-intel modprobe: ERROR: could not insert 'kvm_intel': Operation not permitted Is it still possible to create some KVM type virtual machines with this laptop, to be ported to the VM host server machine later, or do I need another laptop with the required CPU flags?

Hi Marcos. The processor is an intel centrino in an acer aspire 5735 laptop. I’ll take another look at this problem later, and post the exact error message asap.

I tried modprobe kvm and that loaded that kernel module. I got an error trying to load the kvm_intel module though. Kind Regards, Keith
