Hello, all. Hope all is well Is it possible to install kernel and support files from 6u7 into a base 6u5 image to achieve full broadwell support in 6u5? We are "locked", clearly not fully since willing to up jump kernels, on 6u5. Thanks for any and all help

Hi I wonder, if live migration (back and forth) is possible on mixed Haswell (Xeon V3) and Broadwell (Xeon V4) installations. The only notable difference between the two is apparently a working TSX implementation on V4, which got disabled on V3 due to bugs. The rest (VMCS-shadowing, posted interrupts) should not apply to our environment, as we do not run nested-vmx nor device-passthrough on ou...

It may or may not function correctly. That setup would NOT be supported for RHEL (for example). Yo...

"Locked", meaning you're running a ~3 old OS with no security or bugfix updates? thats not good. All centos 6 systems are the same base version 2.6.32 kernel, with fixes...

Thanks much for the the reply! Some sec updates/bug fixes have been applied thru the run of 6u5 and after, but yes, still firmly in 6u5 land. Guess will have to test. Broadwell cpus do run in the OS, but "6u5" is stated as not supporting 26XXv4 chipsets. regards On Wed, Jun 15, 2016 at 4:56 PM, John R Pierce <pierce at hogranch.com> wrote: > On 6/15/2016 2:48 PM, jsl6uy js16uy wrote: > >> Hello, all.

...on another machine), but the VM itself never starts. In one case, the VM host remained somewhat functional and killing kvm/qemu/libvirtd didn't reduce the CPU load. The main difference between the setups is that the older laptop had a Sandy bridge(? Thinkpad W530) and the new laptop is a Broadwell (Thinkpad P70). I've tried to loading vhost_net without much luck. I have, of course, enabled nesting on the actual hardware: cat /sys/module/kvm_intel/parameters/nested Y Any tips on how to debug? I'm in quite a pickle with this, so any and all help is much appreciated. -- Digi...
