similar to: how to update ucode with xen

it is working thx a lot... but it has included the GenuineIntel.bin only in actually used kernel... do I need to reinstall microcode_ctl every time I update the kernel? And second question, I quess I still need the ucode = scan as xen parameter right? Am 2018-09-19 20:08, schrieb Kevin Stange: > On 9/19/18 1:55 AM, Christoph wrote: >> >> Hi >> >> can someone say me

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

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

Package: xen-hypervisor-4.5-amd64 Version: 4.5.0-1 Severity: normal Dear Maintainer, according to the documentation the option ucode=scan should tell XEN to look for a microcode update in an uncompressed initrd. While I don?t use the Debian kernel the tools to generate the initrd are part of Debian. The command ?cpio -i < /boot/initrd.img-4.0.2-Dom0? creates the directory structure

Hi folks, Firstly; apologies in advance for what is a head wrecker of keeping on top of the speculative mitigations and also if this is a duplicate email; my first copy didn't seem to make it into the archive. Also a disclaimer that I may have misunderstood elements of the below but please bear with me. I write this hoping to find out a bit more about the state of the relevant kernel

Current versions of what? Microcode? Well, that's the only thing Intel provides for CPUs, so that's all it can be. > What these means for people who

Dear All, An update just brought on my CenOS 6 boxes updated microcode.dat files: /lib/firmware/microcode.dat Does anybody know off hand what (how critical) is that, as, if it is related to most famous these days trouble with CPU hardware, I will need to reboot relevant boxes to have new microcode loaded. But if it is not that critical, it can wait till next reboot. Thanks a lot and

From: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Hi all, This series adds a new microcode driver for Xen. The Xen hypervisor can deal with all the low-level details of doing a microcode update (Intel vs AMD, doing all the physical CPUs present on the system, current and future, etc), so all the driver has to do is make a hypercall to upload the microcode into Xen. This only

/etc/init.d/microcode_ctl start /etc/init.d/microcode_ctl: microcode device /dev/cpu/microcode doesn't exist? This is on a clean install from the 4.1 x86 ISO. This is the 2nd box that is reporting this error.
